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
