We have had this recurring issue for a long time now, and despite searching the error all over the place, there seem to be a lot of other IT professionals in the same boat, but no obvious answers. The error is on the Anti-Virus setting on the default compliance policy. 2016345612(Syncml(500): The recipient encountered an unexpected condition which prevented it from fulfilling the request) The compliance policy in question is assigned to all users. This is a very annoying issue as it stops users from being able to access any MSFT apps as it marks the device as non compliant. we are forced to add users to the exclusion list of the policy until the error clears on it's own days/weeks later. If anyone has any ideas on what could be the cause or any possible fixes, it would be greatly appreciated

Ok so we also have this error for some devices for some customers. This customer uses a password and PIN to sign-in. Lot's of them only use their PIN. The password was recently changed (a few days), is correct and every application works with it. I could fix the not compliant issue by locking the device and sign-in with the password instead of the PIN. Then rebooted the device and let the user sign-in with the password aswel instead of the PIN. Started multiple syncs from the Settings > accounts > work/school > Emailadress > Info > Sync. Suddenly, after 10m and many many many refresh of intune device page later the device came compliant =)

Change default windows compliance assignment group to device instead of user

Current situation: So we have an Device Compliance Policy for W10/11 where Firewall is Enabled. (MarkDeviceNotCompliant = 1 Days). We use a Dynamic Security group with a DevicePhysicallds filter: "(device.devicePhysicalIds -any _ -startsWith "[OrderID]:User")". Hostnames are less then 15 characters. We use GlobalProtect VPN, which will not work if the device is in de Not Compliant state and shows us the device does not comply with the Compliance Policy because the Edge account is not signed-in and synchronizing. Strangly all other apps work fine. We see that mostly new or reprovisioned with autopilot devices are getting the error on Firewall: "2016345612(Syncml(500): The recipient encountered an unexpected condition which prevented it from fulfilling the request)" So firstly, we checked the firewall on the devices, which state is Enabled and no errors on the device. Disabled the Firewall multiple times and performed multiple quickscans and Syncs after that. As mentioned as a solution on many forms. Sadly it only fixed it on one device. So we researched a bit more on the internet and came accross multiple actions we could try as follows: Check Edge > logged on + sync > Sync device no result Laptop login > Password Recently changes password? > about 2 weeks (sometimes Lock device+ signin again works) Defender Quick scan + Sync device no result Sync from Settings > / work/school > No result Disable PANGPS (Windows service for GlobalProtect VPN) Check CPU time > 16h > Rebooted machine > Sync device no result Powershell: Start-Process -FilePath "C:\Program Files (x86)\Microsoft Intune Management Extension\Microsoft.Management.Services.IntuneWindowsAgent.exe" -ArgumentList "intunemanagementextension://synccompliance" & Get-ScheduledTask -TaskName “Schedule #3 created by enrollment client” | Start-ScheduledTask Lock/reboot: Lock device and login with password > functional Reboot device + sign-in with password > functional Sync from Settings > / work/school and from company portal The strange thing is, we could fix the issue on two devices where we just had to Lock device and Sign in with Password instead of PIN code and sync the device. After that it came compliant. On another device we could fix the issue by performing a quickscan and a Sync. After we tried every step mentioned above and after that it came compliant. On again another device we could fix the issue, after trying everyting mentioned above, with the mentioned Powershell commands which perform a Sync. On again another device we could fix the issue after signing in with the Local Admin Password configured in Intune. Sync within that account and then sign-in again with the primary user. Further research: [https://learn.microsoft.com/en-us/mem/intune/protect/compliance-policy-create-windows#:~:text=Device%20Security-,Firewall%3A,-Not%20configured%20(]( https://learn.microsoft.com/en-us/mem/intune/protect/compliance-policy-create-windows#:~:text=Device%20Security-,Firewall%3A,-Not%20configured%20() Checked if there is an GPO with a Firewall settings what could override the Intune policies > no GPO active as far as I could find. I also checked the IntuneManagementLogs if I could find something helpfull but sadly it did not pointed me in any direction. So, I really have no clue what the root cause of the issue is here because of the multiple actions that could fix the issue.

we have same issue, if i have only virtual windows 365 machines, if i start to sync over company portal after issue was repaired. when it happened in laptop, after i tried more stuff but it didnt help. what solve that issue was switch off windows hello , after 1 day it works like before.

Had the problem since I started using Intune for my clients. Devices will randomly fall out of compliance and get back compliant. Always the firewall and antivirus with Syncml(500) error. This will happen for domain devices, Azure only devices, pre-provisionned devices, etc... it doesn't follow any logic, it's just random. This is the reason why I will never make a CA policy for compliant devices.

I also wanted to note that we started seeing OneDrive not silently login or preform known folder redirection on a few of our accounts. While troubleshooting the problem further I noticed that we are also seeing: 2016345612(Syncml(500): The recipient encountered an unexpected condition which prevented it from fulfilling the request) on specifically my account and a co-workers with reguards to the antivirus and firewall categories. This appears to be happening on freshly enrolled PCs through autopilot and existing PCs in my fleet. We use Microsoft 365 Defender for our Antivirus and firewall solution that are UpToDate. I have not seen the problem occur on others within our school district but that doesn't mean that it isn't happening which is scary because it could give users a false sense that they are signed into Onedrive when they are not. Problems started occurring around mid-July 2023 for us.

Our device names are 15 characters or less. We have removed and redeployed machines, removed and recreated the compliance policy. The issue may resolve for a while, but it always comes back.

Hi,

For our environment we resolve this by letting the user click "Fix now" under the Work or school account settings menu.

After that they can click on "Check access" under the device menu in Company portal.

Keep having this issue intermittently affecting random users using random AAD hybrid joined Windows 10 endpoints.

Machine names are less then 15characters.

Fixed the issue once by running sync from Endpoint and InTune.
All other times need to wait days to weeks for the issue to resolve itself, else delete the endpoint from InTune and AzureAD then do a fresh Azure AD hybrid + InTune join.

Myself and colleagues gave raised tickets with MSFT 365 support who aren't much help, leaving poor 1st line guys struggling when a senior team needs to get involved and gather debug logs to determine the actual cause.

Same here, only a few devices. Firewall is active (Via Intune Policy), AV = Defender (Managed).

We have a culprit, not sure.... will see if it helps:

Our compliance policy was assigned to all users & all devices.

Resetting firewall defaults didn't help.

Checking compliance via Companyportal (last checkin 40 minutes ago) takes forever, reboot doesn't help.

Same issue here: It occurs randomly after users restart their machines. Sometimes, a sync is enough to fix the issue, but other times we have to reboot the machine, sync, check for compliance, and repeat the process multiple times.

We use Windows Defender AV, and our machines’ names are only 11 characters. Last year, this issue was happening very often, but Microsoft fixed it. However, we now observe the same issue occurring since the beginning of March 2024.

Hi Guys, i have had this issue for several users. fix is to turn off the windows firewall and turn it back again. then go to company portal click once on check access and wait 2-3mins until it completes. do not click again and again as it will then take more time. if its taking way too long turn off the conditional access policy that check for compliance. then once company portal check is ok you can turn on the conditional access.

To verify further you can check azure ad portal devices and select the device you are checking on. check if its compliant. Then you can go to intune portal check if it shows compliant. it may be compliant on azure ad and not in intune. give it some time and then it will show compliant on intune as well.

So I have this on multiple instances of both Win11 and Win10 machines for various clients (different intune configs, different methods of setup), I've poked and asked around, mostly from what I can see it's a sync issue. Again cloud loves to take its time with these, and its v. intermittent.

With Stricter compliance policies it appears more frequently than less relaxed policies but I will try and investigate further into this, I don't really have a concrete answer to this other than sync-ing devices.

Usually (on device) i'll run intunemanagementextension://synccompliance in the run diag

This usually clears up after about 10-30ish minutes

We continue to have this issue several times a week. We either wait several days for it to clear on its own or have the user initiate a sync, reboot, etc.

We have opened issues with MS Support only to be passed around to different agents/techs with no solutions offered.
Our compliance platform was integrated to Intune to pull device status,. This became unworkable with this issue occurring so often, so we had to go a different route for that.

It is unfortunate that an issue that is this widespread gets no attention from Microsoft, and support is not helpful.

Yes.. I got this update this week, but still no details around what the fix is so I can say it actually will fix the issue.

I have see other orgs will move to custom compliance policies to do the checks for these items which is more accurate. They write a custom script and json responses to validate the fw/av settings are correct. I haven't done that myself, but I heard it is helping them.

"There are several CSS Engineers that are monitoring this request / issue with our Engineering team. We have a received an update on a corrective action, however, we do not have a date just yet for the completion. We are attempting to ascertain a definitive date from Engineering and then I will advise. As this has slipped before, we do not want to publish a speculative date, so once Engineering provides a definitive date, I will share it with you."

Been hassling with this issue for several years, ever since started using InTune.

I really don't get how big business corporations and governments see this as a viable product with the amount of hassle it is to use.

But as to the syncml(500) issue, once confirmed Windows Security on the endpoint reports no issues I've been able to clear the bug twice now by:
0. Run sync from device endpoint in InTune MDM admin centre

Run sync from device endpoint itself, Start>Settings>Accounts>Work&School>Domain>Info>Scroll to bottom, click Sync

If possible, disable Windows fast startup from Control Panel>Power>Choose what lid does>Untick fast startup if option listed and ticked

Shutdown, wait a minute or 2

Power on, logon

Run sync from Start>Settings>Accounts>Work&School>Domain>Info>Scroll to bottom, click Sync

Install Company Portal app, run sync

Shutdown, wait a minute or 2

Power on, logon

@Nick Eckermann Thank you for your updates on this - We're seeing a similar issue and have referred our Microsoft Support contact to your ticket number. Unfortunately I've not managed to have them get in touch with the engineering team yet... I'm still just getting documentation quoted back at me.

~~I was wondering if you had any updates from MS recently? It sounds like the fix just keeps getting delayed over and over again.~~

*Edit - I see you posted a week ago that you'd had another noncommittal response from them. No surprises there! Fingers crossed they finally get it sorted soon.

We recently onboarded our devices to Intune. We had no previous MDM so all these devices were never managed by anything before. After using the default the Firewall Windows default policy as our base policy, we started to get this error in our compliance report. I took the provided policy, duplicated it and renamed the duplicate. This fixed our issue.

We have the same problem, Intune support unhelpful and will not recognize it as Intune problem. Windows team blames Intune. Intune support refers to this thread as it would be official answer... They told to do windows 10 updates and our devices are Windows 11 and the character limit which is not documented to my understanding and is happening to devices less than the recommended character limit. Same error for Firewall and Antivirus. Would be great to get actual technical help.

I thought we could rely part of our security on Conditional Access requiring compliance.

but with 5-10 false positives each month its not reliable

FIRST i thought it only happend on Hybid joined computers or computers from acquired companies "joined EntraID as is" but we see it frequetly on "pure" Autopilot reshly picked up computers

Great with the workaround - thanks!

Another report of this for multiple devices. Device Names under 15 characters, Defender as standard AV and fully patched and up to date with Fresh Synch completed locally from device.

Nick Eckermann may be onto something as we have seen this occurring more on pre-provisioned devices where they have been built but the use reenrollment step may be completed several days later or used sporadically after deployment.

Either way MS needs to acknowledge and patch this there so many people reporting this you think there own firewall product and AV could talk to their own systems correctly!

Microsoft was having issues this week attempting to deploy a fix for the issue that has been around. It accidentally caused issues with devices that should have fallen the error state grace period to be marked non-compliant immediately depending on if a user was on the device or not when it ran a compliance scan. It was supposed to be mitigated late yesterday after to resolve the new issue. Time will tell if it solved the overall problem with the syncml500 errors.

I'm running into this too specifically with the Firewall.

101 devices but 5 of them aren't happy with 2016345612(Syncml(500): The recipient encountered an unexpected condition which prevented it from fulfilling the request)

Hybrid Joined with Auto Enrolment.

Confirmed the device name is under 15 characters.

Confirmed the firewall is on

Tried resetting the firewall to defaults.

Triggered syncs from Intune and from the client-side (Accounts->Work or School->Info->Sync)

Used the Company Portal 'Check Compliance'

Triggered syncs via

Trigger a compliance check via local process on PC (use remote shell or execute locally)

Start-Process -FilePath "C:\Program Files (x86)\Microsoft Intune Management Extension\Microsoft.Management.Services.IntuneWindowsAgent.exe" -ArgumentList "intunemanagementextension://synccompliance"

Trigger a sync via local scheduled task on PC (use remote shell or execute locally)

Get-ScheduledTask -TaskName “Schedule #3 created by enrollment client” | Start-ScheduledTask

Nothing is helping - to the extent I had to simply exclude them from the policy which is ridiculous... does anyone have any other bright ideas?

Hello, Check if your user has at least one Intune license and that he can sync successfully.

In my case, I had users who do not have a license, neither intune nor Office, nor anything.

And I was able to go through users who have Co-manag SCCM licenses (flag). then my workstations became compliant.

Pretty sad that this is still an issue years later.
Sadly, MS devs seem at times to conveniently ignore these ongoing issues without offering much support.

Started to seeing this again since last week, created a copy of our existing compliance policy, changed the assignment from devices to users and it fixed the problem, temporarily.

Next day the device appears to randomly complain about compliance with syncml 500 error again, sometimes AV, firewall or defender updates or all of them.

However, with the new policy, a manual check-in from the device does remediate it again, whereas devices with the original policy, stubbornly never went back to green, no matter what we've tried.

Definitely a reporting bug in Intune, thinking of creating a custom compliance policy and ditching the template generated one.

Hello, I have deposited the following remediation script in Intune. The commands can also be easily executed in Powershell.

Get-ScheduledTask | ? {$_.TaskName -eq 'Schedule #3 created by enrollment client'} | Start-ScheduledTask

Start-Process -FilePath "C:\Program Files (x86)\Microsoft Intune Management Extension\Microsoft.Management.Services.IntuneWindowsAgent.exe" -ArgumentList "intunemanagementextension://syncapp"

Start-Process -FilePath "C:\Program Files (x86)\Microsoft Intune Management Extension\Microsoft.Management.Services.IntuneWindowsAgent.exe" -ArgumentList "intunemanagementextension://synccompliance"

Started having this issue with some Entra-joined Windows 11 devices, really disappointing this issue has been unresolved for so long. Not even a useful error message...

Ok so we also have this error for some devices for some customers.
This customer uses a password and PIN to sign-in. Lot's of them only use their PIN.
The password was recently changed (a few days), is correct and every application works with it.

I could fix the not compliant issue by locking the device and sign-in with the password instead of the PIN. Then rebooted the device and let the user sign-in with the password aswel instead of the PIN.

Started multiple syncs from the Settings > accounts > work/school > Emailadress > Info > Sync.

Suddenly, after 10m and many many many refresh of intune device page later the device came compliant =)

That's allready the case in our case :) Got that checked right away.
The group assignments are groups which contain devices. That is not the issue unfortunately.

Well, it resolved the errors in my case on the spot.

We had the compliance policy assigned to All Users.

We'll try to All Devices instead and watch it for a while.

Current situation:
- So we have an Device Compliance Policy for W10/11 where Firewall is Enabled. (MarkDeviceNotCompliant = 1 Days). We use a Dynamic Security group with a DevicePhysicallds filter: "(device.devicePhysicalIds -any _ -startsWith "[OrderID]:User")". Hostnames are less then 15 characters.
- We use GlobalProtect VPN, which will not work if the device is in de Not Compliant state and shows us the device does not comply with the Compliance Policy because the Edge account is not signed-in and synchronizing. Strangly all other apps work fine. We see that mostly new or reprovisioned with autopilot devices are getting the error on Firewall:
"2016345612(Syncml(500): The recipient encountered an unexpected condition which prevented it from fulfilling the request)"

So firstly, we checked the firewall on the devices, which state is Enabled and no errors on the device.
Disabled the Firewall multiple times and performed multiple quickscans and Syncs after that. As mentioned as a solution on many forms. Sadly it only fixed it on one device.

So we researched a bit more on the internet and came accross multiple actions we could try as follows:
- Check Edge > logged on + sync > Sync device no result
- Laptop login > Password
- Recently changes password? > about 2 weeks (sometimes Lock device+ signin again works)
- Defender Quick scan + Sync device no result
- Sync from Settings > / work/school > No result
- Disable PANGPS (Windows service for GlobalProtect VPN)
- Check CPU time > 16h > Rebooted machine > Sync device no result
- Powershell:
Start-Process -FilePath "C:\Program Files (x86)\Microsoft Intune Management Extension\Microsoft.Management.Services.IntuneWindowsAgent.exe" -ArgumentList "intunemanagementextension://synccompliance"

&

Get-ScheduledTask -TaskName “Schedule #3 created by enrollment client” | Start-ScheduledTask

Lock/reboot:
- Lock device and login with password > functional
- Reboot device + sign-in with password > functional
- Sync from Settings > / work/school and from company portal
The strange thing is, we could fix the issue on two devices where we just had to Lock device and Sign in with Password instead of PIN code and sync the device. After that it came compliant.

On another device we could fix the issue by performing a quickscan and a Sync. After we tried every step mentioned above and after that it came compliant.

On again another device we could fix the issue, after trying everyting mentioned above, with the mentioned Powershell commands which perform a Sync.

On again another device we could fix the issue after signing in with the Local Admin Password configured in Intune. Sync within that account and then sign-in again with the primary user.

Further research:
[https://learn.microsoft.com/en-us/mem/intune/protect/compliance-policy-create-windows#:~:text=Device%20Security-,Firewall%3A,-Not%20configured%20(](https://learn.microsoft.com/en-us/mem/intune/protect/compliance-policy-create-windows#:~:text=Device%20Security-,Firewall%3A,-Not%20configured%20()
Checked if there is an GPO with a Firewall settings what could override the Intune policies > no GPO active as far as I could find.

I also checked the IntuneManagementLogs if I could find something helpfull but sadly it did not pointed me in any direction.

So, I really have no clue what the root cause of the issue is here because of the multiple actions that could fix the issue.

Laurens,

We dealing with the same issue.

Can you check the value in ExpectedValue when you do a registry search in local machine for ./Vendor/MSFT/DeviceStatus/Firewall/Status

Our problem computers dont have any value and the working computers have Expectedvalue 0.

Still dont know why the value is empty for some computers.

Had the problem since I started using Intune for my clients. Devices will randomly fall out of compliance and get back compliant. Always the firewall and antivirus with Syncml(500) error. This will happen for domain devices, Azure only devices, pre-provisionned devices, etc... it doesn't follow any logic, it's just random. This is the reason why I will never make a CA policy for compliant devices.
