I am trying to migrate via imapsync a Dovecot mail server (host1) to Office 365 (hosts2) (just a test, I love Dovecot).
Imapsync, using dovecot master user, exact command I am using:
imapsync --host1 myhost.mydomain --user1 testuser@mydomain.com*administrator --password1 "XXXXX" --host2 Outlook.Office365.com --user2 testuser@mydomain.com --authuser2 "masteruser2" --password2 "XXXX" --office2
This does not work.
In dovecot logs I get the following error:
Apr 12 09:13:13 buzonus_rhel7 dovecot: imap-login: Login: user=<testuser@mydomain.com>, method=PLAIN, rip=192.168.1.97

This is rather weird. I can access via thunderbird/mutt without problems to Dovecot server with "standard" accounts. If I try imapsync with a "standard" user, with real password, imapsync works. This only fails when I use the master user, can not find INBOX. Maybe a namespace problem using master user?
