I have an issue with this setup.
AAD is installed in Forest 1 -> syncs to 365 Tennant
Full Transitive Forest Trust to Forest 2 where there are users with the UPN that needs to sync to 365 Tennant of forest 1
When initially set up for syncing, I was able to add the forest and it synced the users once.
It never updated forest 2 again.
Forest 1 is fine with syncing. Forest 2 does not get password/user updates.
Any suggestions?
Firewalls are completely open between the two forests domain controllers/and AAD server
