Thunderbird for Android Community Forum

How do I make Thunderbird the default app on my Android 14 phone? It is not in default apps or in the settings menu in Thunderbird on in Apps under the Android settings.

Recently started using Thunderbird on Pixel 9a, Android v16. Just installed newest update to OS. Emails do not sync properly. New messages that are in my Gmail do not show up in Thunderbird until I do a manual update. This is true for all folders, but especially trash and spam. For example, messages that appeared in my Gmail trash folder this morning did not show up in Thunderbird trash at 7 pm MST this evening. When I did a manual sync, 10 messages from this morning suddenly showed up in Thunderbird. In Thunderbird settings, Background sync is set for Always. What do I need to do?

I have been moving slowly from other email clients to Thunderbird. I've been using Thunderbird in Windows for a while now, and decided recently to switch on Android from BlueMail to Thunderbird for Android.

In Thunderbird for Windows, I am able to use unified folders for all common folders (Spam, Sent, Trash, etc.). On Thunderbird for Android, however, only the Inbox is presented as a unified folder. I have discovered that this limitation is really problematic for me for two reasons.

First, if I am in the unified Inbox and accidentally delete a message, I have to check several different Trash folders to find the lost message, selecting each account and then that account's Trash. I anticipate responses asking why or how I could delete a message and not know what it was. With the avalanche of incoming mail the days, I often would use swipe to delete on the unified Inbox for items that are clearly not important-- but occasionally, a real message appears on the face to be junk and isn't. This is a real hassle, and forced me to turn off the swipe to delete a message interaction altogether, because it was too easy to lose messages.

Second, I have several different email addresses, and several different email providers, each of whom applies spam and trash rules differently. Two in particular frequently divert legitimate email into Spam, and I had been in the habit of scanning Spam for errant valid messages from these two providers. Being able to do this for all Spam in one location made this process much simpler.

Can anyone tell me:

• whether there is some underlying reason for this different behavior on Android,
• whether there are plans to implement such a change, or
• whether there are alternatives (like BetterBird, which does not have an Android port) that I could use?

I have a visual impairment. Iwould like to use Thunderbird for Android but after installation AND BEFORE CONFIGURING ANY EMAIL ACCOUNT, I need to play with it (specially settings), so I can check whether I can use it or not. Things like font size, theme and colors are crucial. But Thunderbird does not allow this. It requires an email account. It is a bit ridiculous, I don-t even know if I'll be able to use it!!!

Can anyone please help?

Thank you so much.

I still don't get links in my emails I have tried everything in the forum but no luck I actually get the expanded version. This is only the case with the android app

Hi All,

I am installing Thunderbird from official GitHub releases and I am wondering why I am getting info from Obtainium that thunderbird-14.0 is something called "pseudo-release".

Can someone explain me this term regarding GitHub apk files? Is it OK to install it?

Regards, Timo

I installed MThunderbird on my Android phone today, using a QR Code to import settings. Receiving messages works perfectly, while sending messages is a mission impossible. I keep getting the message when sending: "Authentificanion failed". I have the same settings on my computer, and Thunderbird works normally, both sending and receiving messages. I don't know where the problem could be, so please help!

I'm also attaching a screenshot of the outgoing server from the desktop computer, which is also set up on the mobile application.

Hi,

On my desktop, thunderbird does an awesome job cutting spam. While on the mobile its terrible, not just are most spam mails coming thru but some legit emails are getting flagged. Is there some way to make it mimic the desktop.

Thanks in advance

Installed mobile android app. Manual configuration as other methods did not work. Email received and all well but the Sent folder contains only recently sent mail, which then disappears leaving the folder empty.

One piece of advice is to check a folder called " copies .... " like repair on Win 10 but neither exist on the mobile app. Any guidance welcome.

My primary email (which has been used as the login email for many, many accounts) is on an email server which only supports TLS 1.0. I have contacted the sys admin before and was told they are planning to upgrade "some day" but that was over two years ago so I'm not optimistic.

I've gotten Thunderbird desktop to work with the account by downgrading the minimum TLS level. Recently, I've started using Thunderbird mobile on my phone (as the latest Gmail app update stopped working with my email account -- no doubt for the same reason) and it was working fine but I just bought a new phone and transferred my apps to it. I set Thunderbird mobile up exactly the same way as I did on my old phone, but it is refusing to sign in, citing a protocol problem (so I'm suspecting the stupid TLS 1.0 issue). I don't understand why this worked on my old phone but not on the new one -- the old one is on an earlier version of Android -- could that be it? (Both versions of Thunderbird mobile say they are version 11.1).

So, what can I do about this? There doesn't seem to be any way to downgrade the TLS version on the mobile software. Spending the next two months going through every account I've opened on the internet and changing the associated email account probably isn't as fun as it sounds and I'm inclined to not try finding out. Persuading my email provider to move into the 21st century is probably easier said than done. If I can't change Thunderbird mobile to fix this, does anyone know of another Android email app which would work? Not being able to access my emails on my cell phone would be a significant issue for me.

One of the recent updates mentioned something about changing the colors for read vs unread emails. Now the contrast between the two states is barely perceptible, whereas before it was fairly clear (at least when using the dark theme; I have checked both themes on the current version and they both suffer). Is there a better forum to provide this feedback?

When composing a new message in Thunderbird, I must either type the full recipient address or manually select a contact; unlike other email clients, it does not suggest addresses from previous correspondence. This omission is both time-consuming and frustrating. Any ideas how to fix it?

Hi,

It seems that the last upgrade has broken something with sending emails. With my desktop version, I have no trouble sending and receiving emails. I am using version 142.0 (64-bit) of Thunderbird, and the desktop computer is Windows 10.

I have 2 issues sending emails.

First issue, my Pixel 9 Pro XL does not send emails anymore. It was working fine until recently. The email is stalled in the outbox. I tried reloading the outgoing server settings, I get an error message; see attached error message. My Android receives emails fine, but will not send them. My phone syncs well with my desktop. However, the outbox doesn't sync, so I can't send the stalled emails from the desktop when I'm back in my office.

Second issue is my POS program (Windward Software System 5) stopped sending out emails as well. I worked with the tech department at the software company, and they said it isn't an issue with them, nothing has changed with them, no upgrades or changes on their end. Some of our older machines here, that haven't received the recent upgrade with Thunderbird, are still sending emails fine. Just a couple of computers are having this trouble of not sending emails from out POS software, it's the ones that have received the Thunderbird upgrade. For the outgoing settings, we are using the default port 465, and the connection security is SSL/TLS. Authentication method: is a normal password. I am hoping you have an answer for me. Please don't share the attachment with the community forums. Everything else will be fine.

Thank you,

Hello there I have Thunderbird for Android, version 10.1, and in every folder, all mail, both read and unread, have almost the same appearance. It's not easy to tell which ones in the list are read and which are unread. Is there any setting to turn the unread messages in the folder look highlighted, or more bold, or something different anyway than the rest? Because this way it's very inconvenient, which makes me considering turning back to Outlook. Thanks in advance

I have Thunderbird on my windows desktop and it is excellent. I can not use Thunderbird on my iphone but I have been told it is available for Android phones. If I get a new Samsung phone will I be able to have contacts, calendar and email on it as I have on my windows desktop? I do not use Outlook on desktop or iphone. Thanks for any help! Greg

I'm looking for an Android email client that only shows the headers and optionally shows/download the body of the email and any attachments. The reason is that this way I can save space on my phone while maintaining the convenience of a mail client. I read that K9-Mail, now integrated with Thunderbird, has this selectable feature. Is this true? If so, I'll proceed with installing Thunderbird.

Dramatic change in version 11.0: It's hard to distinguish read vs unread using system theme with android 15 dark mode. It's almost as difficult to distinguish selected vs not selected. This was fine until the last update.

Thanks
