I inherited a tenant of a small company that was bought by our company. Their AD users are all synced to an AD that is now longer available as the previous MSP has offboarded the client and deleted their VMs. furthermore they didn't even have their own cloud sync, the MSP managed Entra through their account and a GDAP agreement.

So moving the the users outside the sync scope obviously won't work for me.

I guess my only option is to somehow nuke the ImmutableID with MSGraph? How does that work? All the information I find points to this was no problem with Set-MsolUser but is a huge pain in Graph? Any pointers to how this is done?
