Thunderbird Community Forum

Dear Community I have had an gmail account on thunderbird for years. In/outbox etc details were still on thunderbird but when checking account details in Thunderbird all info was there as normal.... but.. in "View password"..there was no details at all for this gmail account - but were there for other accounts.

Went to the gmail app and tried login...my email and password are correct...login was ok. I deleted the gmail account from thunderbird and tried to to do "New, Email Account." and entered my gmail account details correctly and hit Done when green gmail 'configuration" is "found".

Then I get a google window to sign into my gmail email account - it has correct email address shown.. I enter correct password and get this message.

"400 Thats an error... The server cannot process the request because its malformed. It should not be retried. Thats all we know"

Thunderbird email setup then shows a yellow box that says "wrong configuration... etc"

Checked in gmail settings and imap is ticked - pop is not. Also checked Gmail "Connections to third party apps and services" and Thunderbird was enabled in April 2021.

Does someone have a fix for this?? or... where have I gone wrong?? Cheers M.

I get a message like this every time I start Thunderbird. The topic came up last year but the conclusion was along the lines of "...this problem will be fixed in version 128" but it was never clear whether or not the User followed Mozilla's support replies or what they had to do to clear the email message from Thunderbird. .....Well I'm running version 128.1.1esr and the problem still exists.

My questions:

1. What is Thunderbird trying to do? Compact individual email files? Compae from ct the whole Thunderbird Profiles folder?

2. Is the problem the size of the Profiles folder or the overall size of the hard drive the Profiles folder resides on? What is the Hard/solidstate drive is the maximum?

3. Is the problem related to the amount of Free Space left on the Hard/solidstate drive or is the issue the number of individual files?

4. Is the issue related to the number of Thunderbird files and/or folders OR is it related to the total number of files and/or folders on the hard drive?

5. Is there a limit to the number of sub-folder levels that Thunderbird can navigate?

Thank you.

Tom

Using Tbird 115 (or later) can gmail contacts be the listing used in Tbird and be in synch when changes are made in the gmail contacts list. There appear to be various methods and I seek the best and simplest. Thanks

I had a problem with a new upgrade for TB and was asked by another moderator on this site to update my version of TB (128.1.1esr 64-bit) to v128.2. My version of TB did not recognize the need for an update and so I downloaded and installed TB 128.2. It successfully installed as an upgrade but in a wholly different folder under C:\Program Files\MozillaThunderbird. The previous instance of TB, 128.1.1, was installed in a different location under C:\Program FIles\WindowsApps\Mozilla Thunderbird. Under control panel I see only one instance of TB and that is the new v128.2. Under Windows Settings, Apps and Features, there are two instances of TB.

Both instances appear to be seeing the mail profile so the only thing I want to know is if it is possible and how to remove the old version of TB without losing the mail profiles. Or do I uninstall the new version and roll back? In any event I do not want to lose a mail profile with years of information.

Hello TBird fans,

I wonder when ThunderBird native client for Android (currently named "K-9") will evolve to a point when internal calendar syncing will work properly, eliminating the need to import google calendars into desktop Tbird ? Is it possible to estimate that time now, or it's better to search for alternative solution(s) ?

I will need an Android synced calendar app soon, I would prefer ThunderBird, since I've been using it for at least a decade, and I'm not even satisfied but became enthusiast also. Best email client ever made IMHO. It would be very convenient to use TBird's integrated calendar.

I've searched the forums for "android calendar sync", but didn't find corresponding info, just this archived thread is closest to my question (particularly the 3. question of it) : https://support.mozilla.org/en-US/questions/1436077

I'm not willing to use google calendar, since I don't want unstoppable notifications and ads when my events are due in time.

Thanks, Peter ;-)

Hello,

After upgrading the Thunderbird to the latest version (128.0.1esr (32-bit)), and trying to switch View->Layout->Classic View to Vertical View, and back to the Classic View, messages from last almost 15 months are not visible. Messages prior to 15 months ago are visible, and from that point, just couple of them showing totally unrelated content than nothing; looks like something is corrupted.

After the latest Thunderbird upgrade, one new message arrived and everything looks OK.

Any hint please?

Thanks. Branko

Hey, everybody. Who knows how to highlight in tags not only the text of the message, but also to highlight the entire line as indicated in the screenshot? Tks!

Hello community. My company decided, right before Christmas, to force-migrate all e-mail addresses from the functioning old servers to "Exchange Online", which not only made the web-browser based access more complicated, but also required changes in Thunderbird. While they provided instructions, which I slavishly followed (despite being usually rather hand around the computer), I still cannot send e-mails with my work address - they get timed out. My company IT are notoriously unwilling to help with issues on the private computer and have recommended even beforehand to from now on only use the web-based access to avoid trouble - which is laughable, for me, as I need my e-mails offline as well. So before harassing them more loudly, I wanted to make sure it's a fault on their end not on mine.

Some details: New server is outlook.office365.com, SMTP port 587. Security level is STARTTLS, authentification OAuth2. These are the changed options requested by the company IT. The window popping up when trying to send a message asks me to chose a certificate for athentification and suggests "Adobe Conetent Certificate 10-7". Neither installing this manually, accepting, or changing something under "further options" changes the outcome that the message will be timed out. As my private e-mail also uses port 587, and it still works perfectly normal, this port is not generally blocked by the windows defender or antivirus (I use Kaspersky).

Maybe someone has an idea what it happening here? Or knows if to slve it by installing a particular different certificate?

Aiming to reduce memory used by my email. I have both Sent and Sent Mail folders. My preference would be to eliminate the duplication that takes place with the two. I understand that I can not unsubscribe from Sent Mail. Could Sent content be reduced to the items that are NOT in Sent Mail? Alternatives? My Sent folder contains more older files which I would like to retain but do not want to "try" something that MIGHT eliminate them. I am on a Mac23 with Latest Sonoma. Thunderbird on Gmail.

I tried to send an email and got a message saying "The message could not be sent because connections to Outgoing server (SMTP) pop3.gmail,com failed. The server may be unavailable or is refusing SMTP connections. Please verify your Outgoing server(SMTP) are correct and try again". I checked and they seem right but I cannot even send an email from one account to the other. The same message appears and I don't believe anything has been changed, aside from adding another address, that I know of.

I am trying to consolidate emails using the Thunderbird identity feature. I have a single email account call it acct1@yahoo.com. I have three other email addresses that get forwarded to Yahoo, call them acct2@pobox.com, acct3@pobox.com, and acct4@hostmonster.com. I can send emails to all of these accounts. In Thunderbird yahoo is the default identity and the other three are alternate identities. The outgoing server settings are all identical (see screenshot). I can send emails using the acct1 and acct2 identities, but not the other two. This is puzzling because acct2 and acct3 are both forwarded identically.

The error message I get is not very helpful: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

Since a recent TB update in August, the program now downloads previously-deleted messages from Gmail. TB downloads from the In folder (OKI), but also current messages that I sent to Trash folder (not OK).

Example: 50 new messages appear in the Gmail In folder. I delete 30 messages from the In folder, and they correctly move to the Trash folder, leaving 20 in the In folder.

I next launch TB on my Win10 PC and press F5 to begin the download. Until recently, I would get the remaining 20 messages and ONLY the 20. Now, TB downloads all 50, as if 30 were never deleted.

                                                       NOTE:  I changed no settings at either end.'

If I go into the Trash folder before downloading and delete today's trash, those messages are totally gone and won't download. But this was never necessary a few weeks ago.

If any reader had and fixed this annoying problem, please tell me how you did it.

I'm trying to copy the data from a PC running xubuntu 2022 onto one running Ubuntu 2024.

I'm following the instructions here (https://www.google.com/search?channel=fs&client=ubuntu-sn&q=moving+thunderbird+data+to+a+new+computer) and all seems to work up to and including "On your destination computer" step 7 (Close Thunderbird). Step 7 "From your Thunderbird profile folder in File Browser, go up two levels" - this sends me to "Common". Step 8 Right click inside the folder, then select Paste.

Here's the problem: we're not told what to click on, but I assume it's ".thunderbird", which only contains 11 items although apparently 348 were transferred. Clicking on empty space (I tried that in desperation) doesn't work. I'm probably overlooking something obvious, but I can't see what that might be. Any suggestions gratefully received. In the meantime, I will keep trying and if I somehow get it to work I'll let you folk know.

I have been using Thunderbird for years and am on 102.15.1, which works well. I want to skip the 115 updates and go directly to 128.2 esr. My email accounts are at hotmail.com and charter.net.

If I run the 128.2.0 esr file I downloaded from MajorGeeks, will it update the existing program or install a second version of Thunderbird?

Also, are there any known problems getting email from hotmail or charter/spectrum accounts that would make it a bad idea to do the upgrade?

Thanks for any help with these questions.

Dear all - I can't send email from Hotmail, and haven't been able to for several years now - I use the webapp, but i'd love to get Thunderbird working again...

I tried following the troubleshooting advice several times, including the most recent 2024 post, and still it won't work...

Here are my current settings, I think they're slightly different from the screenshot, but it still doesn't work!

I've checked my firewall and I don't think it's that.

I am using a VPN.

Thanks in advance, JG

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick
