I will probably be moving from MDaemon to Exchange Online shortly - MDaemon's interface to Outlook is just too slow for remote users. Does anyone have any experiences with the migration that they would care to share?

I have 100 users on MDaemon, some with >4Gb mailboxes, most of them are using IMAP.


I had to migrate one from MDaemon to Exchange 2007,because they had 20 users only, so we just exported each mailbox to a PST.

Setup AD / Exchange and imported PSTs. How many mailboxes do you have on MDaemon ?


Did that in 2013. It was a Royal Pain, because IMAP migration just didn't work and we had to export everyting to PST files. See here for some tips about mail routing, which was also a pain.
