O365 mailbox is not provisioning
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
- I would set this attribute to null via adsi edit on those two users, then do a sync again! The licenses are already assigned right? They need to be in order to create an online mailbox

- If the users are properly licensed for exchange it’s probably due to the msexchmailboxGuid attribute!

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?
