Thunderbird Support Forum

Since I updated to the last Thunderbird version, the messages in my inbox are deleted after one month if I don't "star" them. I don't think I changed any settings? Can somebody help me with this?

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks

After the latest update: Every time I send a message and have selected at recipient, the program searches for a cetificate, allthough encryption is swichted off. A box appears for each recipient for about a minute, unless I stop the search (see image). Essentially, the program acts, as if I had selected encryption. This was newer an issue before latest update.

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

I am trying to do a mass mailing in Thunderbird to about 2015 libraries, with another one to come. I followed all the instructions carefully and generated all the messages and they went into my outbox, with a "send later" command. Then this morning I entered the command to empty the outbox. I immediately began getting an error message that I could only send 50 messages an hour. Feeling like the sorcerer's apprentice, I closed thunderbird, whcih stopped the bleeding. Now I have 1350 messages in the outbox which thunderbird did not try to send.

Fixing up this mess is going to be complicated, particularly with respect to the messages it did try and fail to send (about 750 of them.) But I could make some real progress if I could figure out how to send 50 of the unset messages at a time from the outbox. I have the first 50 out of the 1350 selected right now, but I can't figure out how to get them sent. HELP! Thanks in advance.

Good Day,

For the last few weeks, when using Thunderbird on Windows and writing a draft email, when clicking on the button to create a link, the draft email window freezes. This also happens if I use the menu bar Insert -> Links...

All other Thunderbird windows remain functioning, and I can effectively continue working, but the frozen draft window will remain on screen until closed through Task Manager.

This only happens when creating a Link, not inserting other objects, like an Image. This problem also does not happen with Thunderbird on Ubuntu.

I am running version 115.10.1.

Thanks in advance for any tips that could be of help.

Could not find anything in add-ons, settings, or about:config. There is a topic on this site https://support.mozilla.org/en-US/questions/1086884 but I am not able to follow it because there is no add-on or plugin to enable or I cannot find it.

Using Thunderbird on Linux I cannot delete any local folders, when I try to delete them I get more copies of the folders on reopening Thunderbird, after the system says it is "not responding" and I close it down. I have tried several times and now have multiple copies of the local folders I've tried to delete.

I sent an email with multiple BCCs and no CCs or TOs, I put myself as one of the BCCs.

I did not receive it and I do not think anybody else did as well since I asked a few people.

The email is in the sent folder. I tried forwarding the email from my sent folder to myself as CC, and that worked. I also tried fowarding as BCC, and that worked.

So what is going on? Is BCC working? How can I know for certain? Do I need to foward the email as BCCs to all my BCCs to get this to work?

Thanks for your help.

my wfie sends me windows outlook emails with files that read .eml at the end of the attachment linux 115.0.105 and thunderbird latest, it then reads what should thunderbird do with this file? If i click open with (it defaults to kmail view (default)) if i click on the arrow down i get other, if click on other, I get: celluloid, mpv media player, libreoffice, none of which will open the attachment.

For marital happiness, what do i do? I have tried to stay away from k-whatever. Thank you...b³

I am using Thunderbird and have a Lnux Mint 21.2 Cinnamon operating system. Recently I started using Surfshark vpn, which has blocked the port 587, making it impossible to send e-mails. I have tried using ports 465 and 2525 but without sucess, and apparently it is not possible to set up a split tunnel for Thunderbird. Do you know of any way I can get around this problem?

Since the latest version line spacing is cramped and none of the suggested solutions work. I am having to type my emails in word and then paste them into Thunderbird. This is time-consuming and annoying. How do I get readable line spacing?

Support needs to take their head out of the sand! With the latest release of Thunderbird for iOS it does not work when trying to type a message. The default is "preformat" and trying to change it to paragraph or other does not work. Older version works on my MacBook Pro (2011). My MacBook Air, Thunderbird writing message does not work. Glad I did not contribute money! Oh well must be a way to get folks to purchase Office 365, Outlook?

I was subscribed to a large distribution list, but then unsubscribed. But I didn't unsubscribe. So I subscribed again, but was soon unsubscribed again! My email address and password may have been hacked. So I logged into my Comcast ISP and changed my email password. Then I started Thunderbird, and as expected, it asked for my password, and I gave it. My email came up. I tried sending an email and it asked for a sending password. I ignored it, but after a long delay, it refused to send the message. So I tried again, this time giving it my new email password. The sending then worked. I assumed all was now OK.

But, as a final test, I exited Thunderbird, and then restarted. It again came up OK with my emails shown. Then I again tried sending a test message to myself. But it again asked for my sending password! Thinking this might be a scam, I put in a password of "bullshit". Then I received the following popup message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Polite people say HELO first. Please verify that your email address is correct in your account settings and try again.

What!!! It sure seems like someone (at Thunderbird?) is in the loop grabbing my password before encoding it for storage. A similar thing happened in the past, where I think my account was hacked. So, was this a hacking attempt, and if so, was it from Thunderbird software or my Comcast ISP?

I have inadvertently cc'd a person to a confidential email and not there is no recall option with Thunderbird. This is an option available on all other email providers. How do I recall a message sent in error?
