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)User's image

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

    In several cases like this I have solved by applying the default reset of the firewall one and several times.

    From Control Panel Network Settings - Windows Firewall - Restore default firewall settings

    We are having the same problem, but its not making the device non-compliant? it just brings up an error under the policy and when you click on the actual policy and it says Compliant, non-compliant and other, the said device appears under other?

    We also had an issue with 2 devices. But since we use 3rd-party AV we deleted that and reinstalled it and it was back to a compliant state. Sync device side didnt do anything other then confirm the error.

    We also have started to have this problem. Multiple restarts and checking status from Company Portal app does not help. Security app confirms all services are running with green checkmarks.

    Seems like a problem between Intune system and company portal app. I finally got this to work after 2 1/2 hours with a user. Had to do many restarts and status checking, but eventually the laptop became compliant.

    We just sign up for Intune with in the last month and we were seeing this error as well. I fixed it by duplicating the default firewall policy and renaming the new one.
