April 2023: Needed changes in account settings when mailbox moved from local DTU mail server to outlook365.com
A simple solution for setup in Thunderbird is removing your current account and using Autodetect, it is easy and works fine, including Oauth setup, but no guide yet, so please see server-names e.t.c in the guide below
The guide in this file also works, just restart Thunderbird when server-name or username is changed

Known Issues
Oauth does not work in older versions of Thunderbird, even if it is shown as an option.
You may need to check the settings and restart Thunderbird several times before it works.
You may need to delete your current DTU account from Thunderbird and update or reinstall the program.
