Microsoft 365 Apps admin center devices are not checking in.
None of our devices have checked in since August 2nd. I see no obvious blocks in our FWs or AV systems.
I have checked a couple devices. None of them have a TenantAssociationKey. Some devices have LastCheckInResult as 500 and one has 401.

MicrosoftAre you positive that the devices are meeting the requirements as listed here: https://learn.microsoft.com/en-us/deployoffice/admincenter/inventory#requirements-for-using-inventory as well as that users are signing in with an AzureAD account from your tenant and have launched the Microsoft 365 Apps at least once?
Sorry to drag up and old thread manoth_msft​.
I have the exact same issue if you could potentially offer help...!
Recently enabled cloud update. Have about 8 or so VMs (using device based licensing) that will not report in or show up in the inventory.
On my VMs that do check in (also using device based) I can see many more keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\C2RSvcMgr
Including LastCheckInResult at 200.
This is missing (along with other keys) on my non-reporting VMs.
Also these VM's do not have a TenantAssociationKey, can I manually add it?
Many thanks
