Thunderbird for Android Community Forum

Functionality and usability issue: I use the Thunderbird for Android app as an adjunct to my desktop installation. Recently I had occasion to reply to an email in Android to one "to" recipient and needed to add two "cc" recipients, but found no way to add the cc recipients without deleting the existing cc recipients and having to input the entire (dynamic) group again, but then was also stymied by that. How best to handle this issue?

Other than that issue, the lack of desktop contacts synching, and the lack of spam filtering, Thunderbird for Android has been a huge help, so thanks to the developers for their dedication and hard work.

My email provider sometimes fails to send mail, so I find the mail that didn't send in the sending box (发件箱; I don't know the name in English), use the "edit as new mail" option in the mail 3-dot menu (there's a pencil icon on the top of the screen, but it has no reaction) and tap send button again. I find that every time I do this, the mail's sender identity is reset to the default identity.

I know my Thunderbird version is not latest and is beta, but I'm hesitant about updating. Is it a bug or designed behavior?

Steps to reproduce: 1. Turn off your device's network. 2. Compose and send a mail with an identity that's not the default. 3. Find the mail in the sending box, and choose "edit as new mail". 4. Hit send button. 5. View mail in sending box, it now uses the default identity.

Just purchased and set up Thunderbird on new Samsung Galaxy S25 phone. Message inbox works but Sent, trash, and no other message box displays. How to correct and set up. Also how do you sync android Thunderbird phone app. w computer Thunderbird program. When I delete an inbox message on phone it is not deleted on computer Thunderbird program and vice versa . Computer is new build running Windows 11. Thanks for assistance. Techs at Verizon were unable to help.

Hello all,

Thank you for Thunderbird mobile!

I get a message not sent error when doing the following on Android smartphone: - click an email address link - create email opens - send completed email

Expected result: Email goes to outbox and is removed after sending

Actual result: - email stays in outbox and error cannot send is displayed - when moving email to Entwürfe and send again the sending succeeds, but email is present twice in sent folder

Please have a look!

Best regards Gerrit
