Hi folks,
We have on-premises Active Directory with hosted Exchange server. Mailboxes are stored on-premises, Users are managed on-premises and synced to Office 365 via Azure AD Connect. Configuration is NOT hybrid because of Exchange service provider.
I’m migrating mailbox content from on-premises mailboxes to Exchange online using Bittitan tool.
All users synced successfully, except two.
I noticed that these two users’ mailboxes can’t be synced, because they don’t have cloud mailboxes provisioned.
In the Mail settings of these users I can see message:
This user's on-premises mailbox hasn't been migrated to Exchange Online. The Exchange Online mailbox will be available after migration is completed.
Anyone knows how can I make these mailboxes provisioned?
Thanks

Thanks@adam deltinger ,
As this will clear msExchMailboxGuid for all my users I'll need to re-assign licenses for all of them, right?
What could be other consequences of this?

Thanks @adam deltinger that worked for me!
I cleared the msExchMailboxGuid for both of mailboxes in ADSI , waited for sync and voila.
Mailbox was provisioned straight away for one account, and for another I had to reapply the Exchange online license.
It works now and Bittitan successfully synced messages for these mailboxes.
Thanks!

@adam deltinger Do you know the circumstances under which msExchMailboxGuid can become populated?
