I have a user that has 2 Office 365 mailboxes. Is there an easy way to migrate the contents of one mailbox to the other, rather an export and import.

 

Also could we transfer full ownership of the old mailbox to the new account, thus saving on having to migrate mailboxes?

Do the export/import, it's not that complicated when there's only a single user involved. You cannot have two mailboxes attached to the same user account, nor there are any built-in tools to "migrate" mailboxes in such scenarios.

@Vasil Michev. Thanks. I was trying to avoid exporting a 25Gb mailbox and import it.
