I have a situation where I need to migrate e-mails from Outlook 2011 (Mac) to Apple Mail. Having looked at all options, I have resorted to the, perhaps, most difficult way: Create folders on the IMAP server, copy e-mails into them from Outlook, connect Apple Mail and do the reverse. However, I have hit a wall.
I am running Dovecot 2.1.2 on FreeBSD, with mdbox storage.
In my first attempt, I have 1792 messages in the "Sent Items" folder for Outlook. I have tried (3 times) to copy the messages to the IMAP/Sent Items folder, but the process dies at some point. When that happens, Outlook pops a screen saying "IMAP session state is inconsistent, please relogin". ..

Well, this isn't good. The mdbox was empty when you first started copying the mails? This is a normal local FreeBSD filesystem (not NFS or something else weird)?
What happens if you now run:
doveadm force-resync -u wash@kictanet.or.ke INBOX
Does it show any errors? If not, and if you try to copy the mails again, does it still fail?
It's interesting if you can reproduce this. I wonder if it's because of FreeBSD or if it's related to single instance storage.
