I have a very odd issue with a customer of ours.
He had to rebuild his laptop using Outlook 2016 Professional plus. Now he has 2 email accounts. One for his ISP and one for us.
As far as I can see, the settings are correct, I checked with teamviewer. He can also get and send mail.
In the maillog the user can be seen authenticating, everything goes well without issues.
But then suddenly this happens:
Only when "disconnected" appears, regularly he gets a auth failed. And for this reason DA BFM put's him in the block. If I get him out of the block, he can receive and send mail, and then a minute later or so suddenly this disconnect appears again with auth failed.
I already tried:
./build update
./build dovecot
./build todovecot
./build dovecot_conf
To be sure that is not the reason. As far as I can see, this is the only user having this issue.
He does use a backup of an outlook datafile and we had some issues synching because at first he removed a mail submap from his Outlook which caused some troubles.
If necessary we could delete and re-create this account as it's imap. But maybe somebody knows what's going on, why auth is ok and when disconnecting the auth failed happens.
