Scenario:
- Migrating user cross forest using Active Directory Migration Tool
- AAD connect is in place in OLD AD forest
- Will add new forest in AAD sync scope
Once users is moved to new forest, how do we Match AD user to his existing O365 mailbox profile?
Thanks

HI @Marvin Oco
After migration of users objects into New Forest, Keep those users into one specific OU and change the attribute by PowerShell. You need to change the Immutable ID of each office365 user.
