Hybrid. Can't move the mailbox to EXO

Hello. The creator of the tenant has a mailbox in EXO before setting up the hybrid configuration.


It is exactly the same as on the local server.

Therefore, when moving from local server to EXO, I can't do it. What to do ?

    OK, but its the same user, yes?

    If so, then remove the Exchange License in Azure.
    Then run this:
    Set-User <user> -PermanentlyClearPreviousMailboxInfo


    Warning: This will remove the mailbox in 365 forever!!

    The box is deleted, but now when I send an email from EXO to a local server, to this recipient, I get a bounce back that the recipient is not found.

    I found that because of this local account in Office365, the account in Active Directory is not synchronized in AAD.
