Thunderbird Support Forum

Ever since the Cox-Yahoo migration I am finally getting emails in TB (few glitches). but emails/changes take several minutes to appear/update on my iPhone . My iPhone only option is for Fetch and the time is 15 Minutes..so I have to open the MAIL app and it will look for new/updated messages but it takes a good 2-3 MINUTES to appear. And if I delete a message on TB sometimes it never updates..any suggestions?

When I select "Sent" emails to review to see what I have sent. I find that Thunderbird will not show emails with attached files. (see image) To see what I have sent with attachments I have to select attachments. (see image)

I would think that I should see ALL the emails sent when first selecting "Sent".

I then should be able to view only sent emails with attachments when I select attachments.

Are my settings off or is this a bug in the software?

Let me know. TY

Hi,

Thunderbird suddenly stopped working today,, can not receive emails or send emails. I can log directly into web client and emails are sitting there have confirmed settings with my hosting company and everything is working their end they have also confirmed the settings are correct in Thunderbird

When I launched Thunderbird this morning the right-hand-side panel is completely blank. The left hand side panel shows my folders and if there are any unread emails in them but the right hand side is just completely blank (as per attached image).

Name Thunderbird Version 115.12.1 Build ID 20240618125055

IMAP account on HostGator.

In the last 9 months or so, every once in a while (sometimes several times in a row!) when replying to a message, Thunderbird does not set the \Answered flag on the IMAP server.

I enabled IMAP logging and finally caught this happening. The reply is sent and copied to the Sent folder, as it should, but the original email is never flagged as \Answered.

I can't seem to see a pattern why Thunderbird skips this step, occasionally.

Starting a few months ago Tbird suddenly became noticeably slower, and it's only continued/possibly gotten worse, despite several version updates (which I was hoping would fix it). Currently I'm on version is 115.12.1 (64-bit)

I do have several accounts (all pop) and many folders, but nothing different than before the issue began.

I only have 2 add-ons enabled; Remove Duplicate Messages & SmartTemplates. I've of course disabled them and restarted TBird but it didn't help at all.

I've compacted and repaired all folders.

I've created additional folders to reduce the size of larger folders.

The only thing that helped a bit was troubleshoot mode, which definitely made it a bit better going from email to email and folder to folder, and especially with moving emails from one folder to another (which is usually very, very slow and I see it on the bottom saying "moving email 1 of 10 to folder xyz...moving email 2 of 10 to folder xyz...", even if they are simple/small emails). However, sending emails still took over 5 seconds (see screenshot attached), so that might be a separate issue.

In terms of sending emails, whenever I try to send any email it sits on the sending screen for several seconds or more. My internet is fine (2gb fiber, previously 1gb cable), speed tests max out at the 1gb my laptop can handle. Laptop is 2-3 years old high-end Eluktronics, with no other issues.

Given the above, and that troubleshoot mode did seem to help a bit (but straight out turning off add-ons didn't help), what can I try to adjust (while not in troubleshoot mode)?

Thank you very much!

Its driving me crazy. When I select a group of Inbox emails, and delete them, it is taking forever. The window will display a "not responding" message, eventually clear that and then the emails are deleted. But it takes way too long. Windows 11, most recent update. Thunderbird, it just updated. I was on a Win 10 computer, same Thunderbird version and deleting took merely a blink to happen.

Win 10 has both VPN AND AV. Win 11 has neither. Help! Thank you,

Have used Thunderbird for 10+ years, as interface to Gmail. Lovely product. 3 days ago I had to reinstall a station but when Thunderbird does its updating after reconnecting to gmail address for the 10GB of emails, it behaves damn irregular: - periodic freezes of mouse and keyboard, for about 0.3 seconds every 3 to 5 seconds. - Thunderbird message says downloading email number out of total number of emails (very slowly advancing) but every 3 seconds it starts downloading email 1 of those emails - station has cumulated some 20 hours working, most of these left to finish syncronizing. Usually in 2 - 3 hours there is time enough.

This happens only when Thunderbird runs, when I close it the station runs fine. Same hardware on the station as before..

Did you encounter this? Thanks.

Mam problem z kontem e-mail. Dotyczy on konta obsługi klienta sklepu internetowego. Od kilku dni maile z Amazon, Allegro, Emag itp w ogóle nie dochodzą. Nie wiem co jest tego powodem, nic w ustawieniach nie było zmieniane, stało się to z dnia na dzień. Jak mogę to naprawić?

Hello,

All my outgoing messages are bouncing back to me, no matter who I send or reply to, just from one of my email addresses: heidi@benvenutotravel.com

So I cannot reply to anyone nor send, although it shows copies in my sent folder???

When trying to retried incoming messages, I keep getting popup that ask for my password. I tried to use the hidden password in the app, which till now has always worked, but get the following message:

"Sending of password for user (parrotdise13@att.net) did not succeed. Mail Server inbound.att.net responded [SYS/TEMP] server error - please try again later."

I have browser access to my att/yahoo parrotdise13@att.net account after changing my password. But entering the new password in the above mentioned popup produces same result.

Thanks, John B.

Overnight, I suddenly cannot send emails. I keep getting an error code AUP #OUT-1500 that says: "The email address you are sending as must match the email address you used to auth. " But I have changed nothing. Everything worked fine Thursday when I went to bed; got up Friday unable to send. I can receive all day. And I can send using my provider's website, but I'd rather use Thunderbird as usual. What the heck just happened? None of the Support suggestions work. Thanks for any wisdom you can impart!

Hi I am getting on a daily basis Thunderbird Not Responding, so I have to start Task Manager to close the program and the open it up again. I like this program but this issue is now on a daily basis and has been like this for a couple of weeks now. Kind regards Jim M

I have tried multiple times to add an email account to thunderbird in windows but I keep getting the error, "Unable to log in at server...". I know the details are correct as I'm copying and pasting them from my password manager so I'm not sure what the problem is.
