Given following scenario: - You have the transfercode of a domain - You are already using this domain for several mailboxes using IMAP
I want to migrate all these to office365. But, here is the caviat: Office365 requires me to link my domain before doing the migration.
But, if I do that, then my IP's, MX-records,... are resetted, so my mails won't work anymore?
Or how would one go to migrate the mailboxes in a scenario like that?
I'm aware of imappsync and the build in migration tool of office365, but those all have the same problem (both mailboxes need to exist, but I can only link 1 domain to 1 system)?
Thanks
