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.

Apparently intune thinks (defender firewall) real time or cloud protection setting is not enabled while in reality it is. As I mentioned before, retire the machine from intune, delete from azure, than try to reset windows on the machine, let it re enrol to both azure and intune and chances are the issue will be gone. No more compliance errors. Resetting machine apparently does not resolve the issue, that's just a workaround on win11 machines. MS need to fix that. Let me know if the above procedure helped. Thanks

The exact same issue and error will randomly affect our machines. No third-party AV, OneDrive first starts complaining about device compliance, InTune reports AV is out of compliance due to this error. Computer names are less than 15 characters.

Looks like there are multiple people in this thread having the same problem.
Please open support cases so we can get more traction on this issue, and they can start to get it resolved.

Rename the device up to 15 characters only, it will resolve the issue.

We have been having the same issue since we started using Intune. It hits different computers on different days, and it clears after hours/days/resyncs.
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.

We dont have any hybrid devices, only AAD.

We've just seen this appear in our environment. The Senior VP got an email that she forwarded onto my team for action. Not a good look MS.

Anti-Virus is ESET Protect.

We need this addressed PDQ!

We are experiencing the same issue. Our devices are AzureAD Joined, we do several app installations when the devices is joined. The issue only happens with Windows 11. The machine becomes very slow and AV stops working after reboot. It appears the Microsoft Defender AV (Endpoint security) is trying to restart. EDR show as if it is updating.

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.

We also have a few users affected by this issue (until now all hybrid joined):
2016345612(Syncml(500): The recipient encountered an unexpected condition which prevented it from fulfilling the request)

It's always the Windows Firewall. Never AV (we use windows defender):

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.

@Chad Coker Changes are supposed to be coming but they missed the 2404 deployment. Waiting to see when they might be implemented and if they do in fact fix these issues. Update from Microsoft below. You can reference our case so you might be in the loop better on the rollout.

@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.

Thanks again,
Joe

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.

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!

This isn't a suitable solution. We're seeing this on newly imaged machines (don't ask, save that for another thread) that are joining AAD and enrolling into Intune for the first time. Doing nothing to the devices themselves & just waiting it out seems to sort it out.

We have the same behavior... totally new computers that was bought week ago.

We can only wait now, but some devices resolve itself and some devices broke itself... this is absolutely random behavior...

Interesting... I had call with MS and this is one of expected state...

https://learn.microsoft.com/en-us/mem/intune/protect/compliance-policy-create-windows

If the device immediately syncs after a reboot, or immediately syncs waking from sleep, then this setting may report as an Error. This scenario might not affect the overall device compliance status. To re-evaluate the compliance status, manually sync the device.

I checked it in our environment and it is true, all devices that have problems with error status of compliance policy are compliant because they have also second compliant policy.

It means that it isn't really the problem. Support told that it is an issue in windows and that Intune team managed this problem by configuring this error as compliant state...

It is possible that once the problem will be resolved in windows, then error state in MS Intune will be changed back as not compliant. But this is only my opinion.

However, it is resolved for me, because the unknown state is explained and described on MS websites.

Don't let M$ get of that easy. Like @Efstratios Stratis mentioned it does not work. It also does not explain why some of us also get the syncml500 error on the antivirus component which isn't fixed by a sync.
