• I have used the search function to see if someone else has already submitted the same bug report.
• I will describe the problem with as much detail as possible.

App

Thunderbird for Android

App version

8.1

Where did you get the app from?

Google Play

Android version

Android 13, Samsung One UI 5.1

Device model

Samsung Note 10 Lite

Steps to reproduce

Initial symptom after migration from Thunderbird desktop was that none of the Outlook or Yahoo accounts downloaded emails (pop3). No errors reported in the Outlook case but Yahoo reported that OAUTH2 wasn't supported.

An Outlook example: (the migrated settings are outlook.office365.com, SSL/TLS, 995, Oauth 2.0, username, None)

Tap "Settings"
Tap any Outlook account
Tap "Fetching mail"
Tap "Incoming server"
Tap "Next"

A Yahoo example: (the migrated settings are pop.mail.yahoo.com, SSL/TLS, 995, Oauth 2.0, username, None)

Tap "Settings"
Tap any Outlook account
Tap "Fetching mail"
Tap "Incoming server" - the display asks to sign in and adds "We'll redirect you to your email provider to sign in. You will need to grant the app access to your email account"
Tap "Sign in"

Expected behavior

Outlook accounts:
Presumably a dialog to sign in to outlook to approve Thunderbird access, though since it was already asked for and given as part of the migration, maybe just an acknowledgement that it connected ok and emails are downloading?

Yahoo accounts:
Presumably an acknowledgement that it connected ok and emails are downloading?

Actual behavior

For Outlook accounts the display shows:
"Checking incoming server settings failed
Unknown error
Details:
Unhandled authentication method: XOAUTH2 found in the server settings (bug)."

For Yahoo accounts the display shows:
"OAuth sign in failed
Oauth 2.0 is currently not supported with this provider."

It should work if you use IMAP instead.

Thanks Cketti, so I gather it's a bug and a workaround is to use IMAP, but unfortunately I wish/need to use POP.
I tried IMAP a couple of years ago but Thunderbird ran too slow to be useable, so I switched back to POP. I have 39 email accounts. Some of them are also shared with my wife and/or mother and I want to retain independence (e.g. I don't want to lose emails when they delete them in their client).
Do you know if/when the actual but will be looked at please?
