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

    We have the same issue, no third party AV, laptops updated re-synched multiple times.

    It happens to Win11 laptops only!

    I have recently found that the following commands, in order, fix this issue fairly reliably (syncml issue on either Firewall or AV compliance)

    • Connect to MgGraph with Intune scopes

    Connect-MgGraph -scope DeviceManagementManagedDevices.PrivilegedOperations.All, DeviceManagementManagedDevices.ReadWrite.All,DeviceManagementManagedDevices.Read.All

    $device = Get-MgDeviceManagementManagedDevice -Filter "contains(deviceName,'<DEVICENAME>')"

    Sync-MgDeviceManagementManagedDevice -ManagedDeviceId $device.id

    • 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

    I can confirm we are a Defender shop and seeing this as well, specifically for the Firewall setting within Device Compliance. It seems to resolve itself after a few hours, but OP mentions, it locks users out.

    Hello all,

    unfortunately, we have the same issue and all our computer names are up to 10 characters long. So this (renaming) will not be the solution for everybody.
