I-Thunderbird Community Forum

I have version 153.02esr. Since two days ago I cannot reply or forward messages. It pulls up the appropriate page but there is no box to send, the space is just blank in the upper left hand corner.

I changed my password for Greenby/Plusnet today. Now Thunderbird is unable to connect to them. The password is correct as I can enter website directly. No problems before change. Grateful for help.

Should I reinstall?

For whatever reason after the lastest Thunderbird update Windstream is refusing the connection to Thunderbird email client. I have gone through all of the delete .msf files for all of the inboxes tried adjusting server settings to no avail on anything.

I succeeded in the Thunderbird transfer method described in these forums when bunging it on an old Win10 laptop. When I come to try the same on a new Win11 PC however, setting up an existing email address simply fails. I get as far, in the Set Up Your Existing Email Address page as "Configuration found at email provider" but can proceed no further as I get the message "Unable to log in at server. Probably wrong configuration, username or password" The setup on my old PC is gone now, it finally gave up the ghost, I have email on the old Win10 laptop but that's far from ideal. Additional facts: it's an ntlworld email address; there's a possibility the password may be redundant (so many of these to be found when a PC is on its last legs) How do I get it onto this Win11 PC?

I have a large number of filters, and an important email was processed to move message into a folder. but the filter had no rule that would apply to the message. all the filter criteria were based on the sender, but that email did not have that sender. the filter log shows the filter being applied anyway. I suspect the filter database is corrupted. How can I fix that? i noticed my version is slightly out of date, and I will update it, but I dont expect that would fix a corrupted filter database .

Hi everyone!

I'm trying to log into my email account on the domain example.com via SMTP. The email account is with yandex.ru. When I try to authenticate, it says the SMTP password is incorrect. I decided to try through Outlook, and it worked. What could be the issue?

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.

Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [SYS/PERM] Your account is not enabled for POP access. Please visit your Gmail settings page and enable your account for POP access.

Sending of a message failed because the Outgoing server (SMTP) send@xtra.co.nz failed. The server may be unavailable or is refusing SMTP connections.' This has happened irregularly over the last 2 months or so, even with a complete shutdown of all devices, power off and restarts. This is occurring in New Zealand. I have tried the suggestions from the web a few times, they have not helped

Last week I deleted about 600 emails from the inbox, leaving about 500. I shut down the computer for 5 days then rebooted. TB seemed to start up ok. I deleted the remaining 500 emails. Emptied the trash folder. Tried to pull new emails to the inbox. I usually receive 100 - 200 emails per day but could not receive any this time.

I updated my Mac to Tahoe 25.5.2 recently. After the update my e-mail – Thunderbird- would no longer work. I was able to connect Thunderbird to the my university gmail account and can now read my e-mail, but I am unable to send e-mail from Thunderbird and I get a request for a password. When I enter my University password, I get the same message back. I only have one University password. What password is it asking for? The help lien at the university if not of any help. The segment below from University material point ou that I do need a second password. Where do I get it from?

2. If you are a UMN Google (Gmail) user sending from a desktop client like Thunderbird, you must use the authenticated relay smtp.gmail.com and sign in with an active Google account plus a Google Desktop/Mobile client password (your regular UMN password may not work for this).

I ran TB in troubleshooting mode and the problem was still there. I deleted the account and created it again but it did not help. I killed TB and restarted, no joy. I rebooted Windows (build 26200.8875), no help. I have a working hotmail account so I compared the Account Settings and Server Settings, they are identical. Both accounts can contact the Mail Server and I get the Certificate ok. I could add the hotmail email account to my Mail app on iPhone and iPad and that worked fine, so seems like a Windows Thunderbird issue. I tried changing the password of the account to the real password but then restarting TB I got an error message: "login.microsoftonline.com needs you to confirm access again to keep syncing with your account. Username: <foo>@hotmail.com". I do not know how to handle that.
