Import from Outlook or Exchange Server (emails and calendar)

[eXTric]

You can easily migrate inboxes using Imapsync

Can I migrate emails from a cPanel account to MiAB?

I am not aware of a mailbox limit when i hosted the tool myself. https://imapsync.lamiral.info/INSTALL.d/INSTALL.Debian.txt I believe there is only a limit when when you use the online service. https://imapsync.lamiral.info/X/
