There was an error reading the rules from the server. The format of the server rules was not recognized

wchrisb 16

****NOTE:** I originally posted this in the standard MS Community Forums. They redirected to TechNet that redirected me here.**

I have recently been upgraded by my email provider (GoDaddy) to a new email server which requires using MS Exchange. In making that change, my rules began to have problems. I recreated all "receive" emails on the server via Outlook.com in both email accounts affected by the move to Exchange. Once created, I deleted the same rules I had created locally (client only). The system worked great for about a week. Then, earlier this week, I began getting the message "There was an error reading the rules from the server. The format of the server rules was not recognized" on one of my email accounts. I have been unable to get this to stop since. I completely disabled the rules no the one account to see if that would do anything and it did not. It should be noted that the rules are running on the server. They have disappeared locally and I get the error message anytime I log into my local version of Outlook or try to manage the rules from my desktop.

Is there a way to resolve this issue?

This worked for me.

Export the rules out to local file.

Delete all the rules.

Restart outlook.

Open Rules again, if you see (client-only) rules again delete them all.

Create any simple rule and save it.

Restart Outlook

Open Rules, this time you will be asked to choose which rules you want to use "client" or "server" choose client.

Import the saved rules from step 1.

Hope this helps.

Hello!

I'm facing the same issue here, but I don't understand how you could export the rules to a local file if the rules were all gone from the desktop app, and only visible and functional on the web.

Could someone explain those first steps, please?

Thank you!

Very helpful,

I found that once you get down to a single corrupt rule you can carry on with 5. and it will still work

Saw this and didn't feel like it would work. Backing up rules resulted in a file 130bytes in size. Did this against my gut feeling and now just have no rules at all. Here is a morning of recreating them all ...

The @Amit Dodake solution worked except for step 1. I was not able to export the rules from computer A as there were some client side rules related to computer B that were marked as being in error as well as having a corrupt rule from the server present (which is what started my whole problem) that could not be deleted. Fortunatly I hade an exported rules file from several months ago (before the corruption) that I could use in place of step 1 even though some of the rules in that backup needed to be updated.

Could someone please explain what is meant by a simple rule in step 5?

This has happened to me many times over the past few years, and depending on whether the "simple rule" is considered to be a client or a server rule, sometimes it doesn't work. But I can never remember which one.

Update

When I created a messages received from person, move it to Inbox rule, I wasn't prompted where to save when I restarted and opened rules.

PERFECT!
I did get the error after exporting, and deleting rules. I closed open and picked server, error continued. Removed all rules, and this time picked client. Removed all the rules, found a broken rule, fixed it. Don't forget to hit apply after each delete process.
Error was cleared and imported my rules again.
badda bing badda boom!

None of other solutions worked :(

Went to outlook.com and logged in to the mailbox
Deleted newest created rule
All worked ok :)

Good luck

The following worked for me:

Export the rules to a local file

Close Outlook

Run outlook.exe /cleanrules (This command will open Outlook and clean the rules) Thanks @Eric Yin-MSFT !

Import the saved rules from step 1

Hope this helps.

This worked for me when the steps above didn't work for me. In between step 2 and 3 I restarted my computer as well. Though I'm not sure that was necessary.

Worked for me when other methods didn't!

Be aware, if you have multiple or additional mailboxes in your Outlook profile, running the /cleanrules command line switch deletes the rules from all connected mailboxes. I then had to re-create the rules in both my primary mailbox, and all connected mailboxes.

Be warned that this command has a far reaching impact if you have additional mailboxes linked to your Outlook profile.

Even though you cannot access rules from linked mailboxes in the Outlook client, "/cleanrules" will remove all rules from all mailboxes. I assume you do need full access to these mailboxes.

For me, this meant several mailboxes that integrate into CRM systems were left without forwarding rules. Not good.

blowing out the rules worked for me but I didn't realize it would wipe out the rules on the server. Wasn't worried as the rules were mostly just moving emails to folders.

I wonder on which step have you been in order to "upgrade your email provider to a new email server which requires using Exchange"? Can you see your mailbox in EAC now?
What you do mean about "recreated all "receive" emails on the server via Outlook.com in both email accounts affected by the move to Exchange"? Could you explain how you did it and what is the final situaltion?

You can try running outlook.exe /cleanrules to reset the rule engine and rebuild the rules on server again.(If you have multiple or additional mailboxes in your Outlook profile, running the /cleanrules command line switch deletes the rules from all connected mailboxes. Therefore, it is recommended that you only run this command when your Outlook profile only contains the one, target mailbox.)
Also, which version of Outlook are you using? See if the error exists when using other versions of Outlook.

Login to your account @harsh.com .com

Under settings Gear button on the right top

Search for 'Inbox rules

Delete the rules which have warnings as below --> This rule can't be edited or viewed in Outlook on the web.

This solved the issue for me.

Creation of 4 new rules in online Outlook (Webmail) created a problem for me. I noticed a few rules with the exclamation mark in online Outlook (Webmail). After that I received an error message in Outlook 365 on PC about server rules. I did everything from one of the initial comments here (deleted local rules on PC and imported them from backup). After that, I saw AGAIN two rules in online Outlook (Webmail) with the exclamation mark. Deleted them. Now both PC and online Outlook work. Incredible.
