Thunderbird for Android Community Forum

My alumni email account is hosted on Microsoft 360. My email address is xxx@alumni.caltech.edu, but the actual login user name is xxx@alumni.caltech.onmicrosoft.com. When I try to log in with Thunderbird for Android the user name is automatically set to my email address rather than the username specified in the incoming server settings. This field cannot be changed and it prevents me from logging in. Please help, and thank you for all of your fine work.

I've tried to use K9 mail and Thunderbird for Android, and with both have had issues sending an email or replying to one and having my email dropped without any notice. I've found that this happens all the time when I send to my own Gmail account. I can send from Tbird for Android to another of my own domains on Hostgator. I can send from my desktop version of Thunderbird to my android version, and to Gmail. Even if I import the desktop configuration to Android, I can't send from it to Gmail, and no notice of failure comes back. Any ideas?

I have installed Thunderbird on a Galaxy Tab S9. Great excitement. It receives POP3 emails OK but refuses to accept the SMTP server. The settings are OK and work on PC. They also work on Gmail on the same machine. Any suggestions? The server in question is Zen Internet, mailhost.zen.co.uk

Thunderbird android fails to login to outlook account with automatic configuration, which also seems to be the Microsoft recommended. On android 13.

Steps: Add account > enter your_mail@outlook.com > automatic configuration > [Accept] in the webview of microsoft asking to authorise TB
