I had to recently change my password on my shaw email account. Now thunderbird won't download my emails. I changed the password in the account settings to match the shaw email account password but I keep getting an error message: "Host contacted, sending login information..." and then after a long delay the error message reads "Login to server pop.shaw.ca with username ... failed". Any idea what I'm doing wrong by simply changing the password? I think this happened before and some wonderful human on this forum told me I had to put something before the password or click/unclick a particular box, but I can't find that old answer to my previous question. Thanks in advance for any help someone can offer!

A few days ago I sent emails and did not see the usual "Saving to Sent (IMAP)". Instead it said something like saving to Sent folder. That's fine, but the emails didn't appear in my Thunderbird Sent folders. I downloaded Thunderbird to see if my version was obsolete. Still no emails in Sent folder. The internet said I could delete my Sent folder, and Thunderbird would re-establish Sent folder. It did not. I can still see my old emails in my Local Thunderbird sent mail, so I deleted about 100 old emails in case the folder was too full. Still, the new emails I was sending did not appear. I checked with a few recipient people and they told me the email go to them. I have tried all the "solutions" I can find. What else can I do to see copies of my outgoing emails.?

I want to configure an automatic response to emails that have been forwarded to me from a particular address. I have created a template for the response and it is saved in the Templates folder. I then attempted to create a Filter Rule to send the response. I believe there should be a Reply with Template option in the Perform these action pull-down, but there isn't. I've attached a screen shot to illustrate this.

I'm using Thunderbird 154.0 and Windows 11. Is there a new way of achieving my objective?

I tested out the incoming and outgoing security server and they both are successful at SSL/TLS but I still cannot send email. Is there anything else I should check?

What are the memory limits for Thunderbird. Currently, I get this message when I try to save and email "Unable to save your message to local folders. Possibly out of local file storage space." Please see attached screenshot.

I am not out of storage space.

Any suggestions?

Thank you.

I never had this problem before. People who get my messages, including the copies automatically sent back to me, have ?? ?? instead of the tabs or  ?? spaces I used in the messages. Messages sent to me from other people come in without the ?? marks. Example of my test message copied back to me: ?? ?? ?? ?? ?? ?? 26 Aug 26

To All: Disregard any "?? " in this message; I'm having some trouble with my email program.

How can I fix this problem?

Mail.com (and all its vanity domains like usa.com, europe.com, myself.com, etc.) & many such domains no longer work in Thunderbird. They used to

After your upgrade I was unable to send messages. The incoming I was able to fix but the outgoing I could not fix. I have included the email message sent to me and I have included a picture of the outgoing STMP,

My email works well most of the time. About three or four times a day now I get a message "The current command did not succeed. The mail server for account <account name> responded: System Error (Failure)." Nothing seems obviously wrong that I can see, maybe some of my recipients aren't getting the emails I send? The account in question is at gmail. I've been using it, and Thunderbird, for many years without seeing this error. It seems to have popped up in the last month or two and is now happening a few times a day. I'm running Windows 11 Pro 25H2 build 26200.9168, Thunderbird 153.0.3 Build ID 20260810194242. I have plenty of disk space (1.15TB free) and restarting my system hasn't helped. Is there a way to turn on more logging to get more information about these errors?

You upgraded my program just shortly and now I cannot send email. Everything worked fine before the upgrade but now I can only receive emails. Please help and tell me what to do.

How can I see my emails , they haven’t come through since 13/08/2024 and I really need it. It’s a recovery email address that I need desperately. Other thunderbird accounts are ok.

It still sends emails fine

Today all my yahoo & aol accounts were locked (About 10) . I had to release all 10 of them before Thunderbird can receive emails on accounts that are not locked (other than hotmail , gmail etc). I am reasonably sure this is not a yahoo / aol issue (though I know they are owned by same company Verizon Media )

Because I have seen this problem in the past with other email domains . If hotmail or gmail is locked then I cannot receive any yahoo emails until I release all locks on hotmail or gmail etc accounts

I read somewhere it may be auth issue such as OAuth2 but all my my settings are correct to OAuth2

After updating to 153.0.1esr(aarch64). the SEND button has disappeared. There's no way to send an email. (I can receive emails.) I am a Mac mini M2 Pro. OS 26.4.1

I cannot find a link to download a previous release of Thuderbird, which was working fine until this update.
