Thunderbird Community Forum

I set up a filter to move messages to the junk folder. If it's not from a .com, .net, or .org domain, move it. Here's how I set it up... If the "from" incoming message doesn't contain "any of the following" ".com" ".org" or ".net" move it to "junk". It moved .com and .org messages to junk anyway. What did I do wrong? There are too many TLDs to create a filter for all of them.

On Sunday, May 7, my Thunderbird program suddenly stopped responding (neither the shortcut nor the program itself will run); clicking on the shortcut icon or attempting to open or run the program itself causes the "loading" or spinning wheel icon to pop up, run for about 10 seconds, then stop.

I've used Thunderbird as an email client for my Sonic email account on my pc for over 8 years without any difficulties until now, and now seem to be locked out of my Thunderbird account. I cannot access it to confirm the version, although I believe it is current, since it appears to update automatically.

My Sonic account continues to function normally, but I keep (save) all incoming and outgoing emails in my Thunderbird system and now am unable to access any of those, and unable to access my Thunderbird account at all..

I've consulted with Sonic over this; Sonic maintains that any difficulty must be on my end connecting to Thunderbird, and suggested that I might have changed the account password. However, I have not changed the password, etc.

Please help asap.

Thanks, immensely.

As of this morning I am no longer able to download or send email via my Spectrum email account. A warning message appears next to the account name reading 'The certificate for mobile.charter.net:993 does not come from a trusted source.' The section from the View Certificate page makes it seem like the certificate should be valid:

Issuer Name

Country BE Organization GlobalSign nv-sa Common Name GlobalSign RSA OV SSL CA 2018 Validity Not Before Tue, 19 May 2026 11:45:30 GMT Not After Fri, 04 Dec 2026 11:45:30 GMT . Spectrum of course says it's an issue with my email client. Adding an exception for mobile.charter.net does work, but that doesn't seem like a good long-term solution. When I attemt to get a certificate for the server, I get a 'No Information Available - Unable to obtain identification status for this site'. I am not using a mail scanner and my only anti-virus is Windows 11 built-in Virus & Threat Protection. Any help or suggestions would be appreciated, thanks.

Hi I am Unable to send e-mails (only receive) after adding a 3rd account to my thunderbird, a microsoft e-mail (the other 2 are gmx and my old work e-mail). This is my private laptop. I tried tons of troubleshootings incl. deleting passwords, triple checking all settings (they are all correct), but I always get a pop up with "Login to server smtp.office365.com with username ... failed" when trying to send an e-mail. When I click on enter new password it just tries to send the e-mail again, which fails, so unable to enter anything.

I accidentally deleted a good number of my emails from my local Pop3 server account. I don't delete my emails from my gmail server so I can just redownload all my emails but cannot remember the prefix needed to do it.

If I recall correctly I go under settings for my email account, then go to server settings and add the prefix to my email shown in the Username field under the Pop Mail Server Section.

Can anyone remind me of the prefix?

It was like restore:[my email] or all:[my email].

I should have made a note of it as I cannot find it anywhere online now.

Today I created a subfolder and moved many precious e-mails there. That move was successful. Thereupon I shut down my Thunderbird and my computer. When I restarted my computer and my Thunderbird the folder which I created was empty. Please let me know how I can recover the e-mails. Thank you.

I have a desktop that is windows 10. I use Mozilla for four email accounts, 3 of my accounts work fine. My problem is with TWC. Emails sent/forward and cant save drafts often fail. When I sign into spectrum webmail, my Mozilla TWC account works again for a while. This started about 2 weeks ago. I'm using version firefox version 151.0.2. I've eliminated Spectrum as being the issue and all my settings are correct. Thoughts?

have 2 filters. want to run 1 on inbox and on spam on the other filter. Cannot enter different folders. When I change one of the filters in the run filter on they other filter changes the value in the run filter on to what I put in the previous filter. How can I have 2 different folders in 2 different filters

I keep getting the following error when trying to download emails from yahoo.mail: Authentication failure while connecting to server pop.mail.yahoo.com Have hundreds of emails sitting in yahoo.mail that I need to load onto my desktop. Any help is appreciated!

French please !

Bonjour,

Lorsque je veux modifier la manière dont Thunderbird est mis à jour, il s'affiche ceci :

"Thunderbird est mis à jour par une autre instance" et il est impossible de le modifier car si on on choisit de le faire, le logiciel thunderbird corrige immédiatement et retourne à la configuration précédente (solutions/choix à cocher, mises à jour automatiques ou manuelles) !

Comment opérer S.V.P. ? Merci à vous. Salutations cordiales. Alain.

Email not working on my desktop. Using Edge 11, Settings show certificate for mobile.charter.net:993 does not come from a trusted source. I can not send or receive email on my desktop. This started this morning. I have not made any changes to my computer, but did do an Edge update. I can check my email on my cellphone if there is a fix.

This just all the sudden started happening for my charter email account, I haven't changed any settings, the font turned red and can't receive the emails. I have mail washer and see the emails, they not from anyone shady. got a couple screen shots. Thanks

The newest version of Thunderbird wiped out the stored files from the previous version by making me create a new identity. I have tried several times to use "import" to retrieve backed up data from the old version, but without success, even after I re-installed an earlier version of Thunderbird. Each time I use the "import" feature I get a message that it failed unexpectedly. I need these old e-mails because they contain receipts for charitable donations that I need because my tax returns are being audited. What can I do?

I have numerous Ionos email addresses. No problem seeing all received emails in Thunderbird app on my Windows PC. But Android app does not show some emails, despite synchronising numerous times. Problem is often with emails not showing in the unified inbox on the Android app. Also a problem with sent emails not showing. Today I looked for an email I had sent four days ago, and it was not in my Android sent folder. Synchronised, still not there. Synchronised again, still not there. Went online to Ionos and opened the sent email. Synchronised Android Thunderbird again and then it appeared. Why can't Anroid Thunderbird see certain emails? Problem seems to be especially bad with emails I have previously opened in Thunderbird on my Windows PC. Doing so seems to make the emails invisible to Android Thunderbird.

My ISP has made a change for "third-party" accesses to its e-mail (which still works fine on its own website e-mail access page). I need to check my Username, Password, SSL, Protocol, Incoming & Outgoing Server Ports. BUT I don't see on my Thunderbird page where to find these: it's my preferred way to do e-mail! Where are they??

Receive popup message: The certificate for mobile.charter.net does not come from a trusted source. In trying to send email, popup message: Sending the email failed. Peer's Certificate issuer is not recognized. The configuration related to mobile.charter.net must be corrected. Then it wants me to Add Security, Get Certificate.

I received a spam message this morning that had a "Disposition-Notification-To" (aka Read Receipt) line that had MY email address on it. I honestly don't know why a spammer would do this - but that's not the issue. I have Read Receipts disabled, but Thunderbird generated an email (to me) and sent it to my mail host. This seems like a bug. Even if the Read Receipt has my email address on it (making it mostly harmless), Thunderbird shouldn't have generated the message. Or am I missing something? Thanks.
