<html><head></head><body><div style="font-family: Verdana;font-size: 12.0px;"><div>I am trying to migrate via imapsync a Dovecot mail server (host1) to Office 365 (hosts2) (just a test, I love Dovecot).</div>
<div> </div>
<div>Imapsync, using dovecot master user, exact command I am using:</div>

<div>
<div>imapsync --host1 myhost.mydomain --user1 testuser@mydomain.com*administrator --password1 "XXXXX" --host2 Outlook.Office365.com --user2 testuser@mydomain.com --authuser2 "masteruser2" --password2 "XXXX" --office2</div>
<div> </div>
<div>This does not work.</div>

<div>In dovecot logs I get the following error:</div>

<div>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?</div>
