Hello @DEMdev
Hello community
Thanks for your feedback. I had included those settings already.
I managed to get a step closer through trial and error, not sure if I like the result.
If I also sync the following keys / files, O365 credentials remain:
[IncludeRegistryTrees]
HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.aad.brokerplugin_cw5n1h2txyewy
HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\PolicyCache\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\Repository\Families\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\SystemAppData\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy

HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppModel\Repository\Packages\Microsoft.AAD.BrokerPlugin_1000.18362.449.0_neutral_neutral_cw5n1h2txyewy
[IncludeFolderTrees]
<LocalAppData>\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
It was also working when I included the common KEY: HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion
The test users email address belongs to an unlinked tenant (because this is only a lab environment) and I do have the feeling, that this behaviour might be related to the AD User logged on not being synced to AAD. I guess the in other posts provided information in regards to O365 would suffice when SSO is in place.
The registry key behind HKCU\Software\Classes\Local Settings seems to me, that it is not meant to be synced across different machines, also as I remember, the ID of the Microsoft.AAD.BrokerPlugin changes between OS releases, which would have to be considered between OS rollouts (maybe through conditions).
If anyone has a deeper understanding of the recorded behaviour or what is stored under HKCU\Software\Classes\Local Settings, I'd be interessted to know more.
Thanks
