<div>I think is an ACL problem for master user. My master user is named "administrator" (static password files), all other users have ldap backend, and I tried to add this to acl file using vim</div>
<div> </div>
<div>* user=administrator lr</div>
</div>
<div> </div>
<div>But still does not work. I have read several times https://wiki.dovecot.org/Authentication/MasterUsers and still I do not get the ACL thing. That page says " Set <tt>plugin { master_user=%u } </tt> This fully hides that master user login is being used ". I have tried setting master_user=%u inside my plugin section and does not work. Can anyone post a doveconf -n output of a static-file master user + ACL working as intented?<tt> </tt></div>
<div> </div>
<div>Regards</div>

<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>
<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>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>
