dovecot-2.3.11.3_1
Hi group, I have a problem with connecting Outlook 2019 client to my
server (BSD 21.2).
Running Postfix and Dovecot.

Dec 12 16:53:41 poseidon dovecot[36185]: imap-login: Disconnected (auth

Providing the correct email address and password.
Strang thing is that with Thunderbird it all works fine; only Outlook is
refused.

(Since other clients can connect via TLS, this is going to be an Outlook problem). -- I took a deep breath and listened to the old brag of my heart. I am, I am, I am.

The problems were never Dovecot related. They were mostly Outlook not dealing properly with IMAP connections, and refusing to refresh the folder/conents lists. Be aware that simply closing Outlook may not be enough, you may have to open the task manager and kill some background stuff it leaves running. I have migrated most of my clients using Outlook over to "eM Client", it has superior handling for IMAP and integrates with caldav/cardav servers perfectly. In the end it was a better solution than Outlook, for the small handful of Windows users I have to support (most of whom use Thunderbird anyway). - -- Nikolai Lusan <nikolai at lusan.id.au> -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEVfd4GW6z4nsBxdLo4ZaDRV2VL6QFAl/VAZIACgkQ4ZaDRV2V L6Qymg//VHtCGYO7gJSATn6IzXbFUBwAKKEfj5DUgEBtQ6E5+XSgoDb5XC+X9Osf bBxvOY7F6Z6guwy2taGiA2FzHq0iS6+ij5sTiEk3oRVQ9fHd9s8e0BZsdQC8MJZG CEk7VYccNYYfL0374XlUnP0WpmCz1RtuQuQsLgWZITVZEsLWpY1lls7OETo6YzTP xD4FwkkzxFCY7UoyAshwwU/O7UpHX4tlxwLlqFCK9pRIit4mwtUN6QC5OzKz6DG4 1QCG8Xvc1jFW24E4av7mJQAHEf0BHA9kwgR1Hj3CTR/cldFFrzzKYjiXDMUP5wFj LtHFBsFCqBlMi9fxlTwUw+f6H41I1//kEuFEgSboQgjOgVCjwhQb9viHjlydjfMU GqAlhp3UIM1vOxnYQs8xr6fGtHfRLPQ3+wQBYmUlnPqQCgeWHESHkWfF5eYdS0M1 oosgA2G533Ioyo9hh+EaDhILithm0U7Ktb0UyxW3UBbc/9ZvSxqgjsuIzcr6+Sag 9BpMfDjAHvfb82isQUUYKQZCyShoPjTXI0ZIaKxxXKhWTUVPaI3CTbacm26nOuJG Bw2itaFk+WhgUPjWSmxH10SThDb2jzLneMB/TNNEFZqyzupcjwQkJa/VdWi8XUUL ODSjpbYnnUQVyNb7hfier/IUk78nJlKRPJbqppBsvq/nuWzN2J0=Ed4A -----END PGP SIGNATURE-----

Setting up a new account in Outlook, one has to provide an email address instead of a user name. With using BSD usermanager, adding a user named 'ilse at mydomain.com' is converted automatically to user 'ilse'. I am not expecting that Microsoft will solve this issue on short term though. Will stick with Thunderbird (as I already planned) but how nice it would be to make Outlook my backup mail client with IMAP/Dovecot/Postfix... Best, E.
