Hi,

We have experienced a difficult activation for some clients.

The environment is based on an On-prem AD with Azureadsync to AzureAD but not with writeback.

Users gets synced as well but there is no writeback there either.

 

What seems to have happend is that local on-prem computers failed to activate with the M365 E3 license and once synced to AzureAD, there is no way to force the client to get the license key again.

 

The only thing that worked for us was to delete the user profile on the computer --> reboot --> login with the UserPrincipalName.

Now the license key for Enterprise will not go away, even how hard I try to clear it and force the OEM or generic Windows 10 key on to the computer.

 

I saw that you do not have anything to do with the customer anymore but this might help you in the future as it was not documented anywhere what I could see.
