Hello Community,

I am experiencing issues where all emails received automatically go to the Deleted folder in Thunderbird, I tried to uninstall the application but the problem persisted. I kindly request for your help.

It only happens when I turn on "Synchronise all messages locally regardless of age"

Regards.

This all started when I cancelled Xfinity and went to Frontier Internet. I had previously used Thunderbird for 8 years through Xfinity with no problems. I have contacted Xfinity and Frontier and both have told me it is a problem with a Thunderbird setting.

Sending of the message failed. An error occured while sending mail: Outgoing mail server (smtp) error. The server responded: resomta-c2p-555920.sys.comcast.net resonta-c2p-555920 sys.comcast.net. Excessive failed authentication. ESMTP server temporarily not available.

I use Mozilla Thunderbird for emails. Somehow I have clicked something and lost the actual email, unless I double click on it and then it appears as though I am replying to said email. I have the columns subject/correspondence/date and that is all. I've tried many ways to get the emails back on screen, but can't see how. I'm not overly computer literate. Many thanks for any help.

Long story short... my ISP's AI spam filter went crazy on me. They finally fixed the problem. I can send my research notes again, but only through my ISP's web mail. But Thunderbird is still throwing a VO-101 error.

How do I reset my spam filter?

Thunderbird 115.3.3 (64-bit). Just updated to 115.10.1 (64-bit). The problem persists.

Win 10 Pro

Also... Feedback: Did a Thunderbird search and automatically clicked the first entry. (Yes... that was stupid.) Ended up at a site that wanted my credit card number. Didn't give them any personal info.

Since 1/2 my Thunderbird email refuses to download new email. Tried everything. No joy. Need help. Do receive error message. "Add security exemption" What happened?

Some emails I receive, when I reply to them, don't correctly display the email (body text) correctly. It looks like Thunderbird is choosing the wrong font colour for the reply email text and I'm after any info on why this happens and how to fix it.

Attached are two screen shots. "original.jpg" shows the original email and "reply.jpg" is my reply email. It doesn't always happen and it *may* be emails sent out by Zendesk.

I'm on latest TBird 128.6.0esr but it's been happening for the last few releases.

Please, I need help. Bear with me while I describe the problem.

Let's say I have two email accounts set up, user1 and user2. Each one has been set up for quite some time and both have worked as expected for years. If I send an email from user1 a copy of the message drops in the sent folder of user1 and the reply comes back to user1, and if I send an email from user2 a copy of the message drops in the sent folder of user2 and the reply comes back to user2. Not any longer.

Now, if I send an email from user1, a copy of the message drops in the sent folder of user1 and the copy clearly says it was sent from user1's email. However, the reply comes back to user2's email inbox. The source of the message clearly shows it was sent TO: user2, Delivered-To: user2, Received: from line says it is for <user2>.

This has been going on since the latter part of last year.

This appears EVERYWHERE: emails unreadable (blurred). BUT if I select (left-button + mouse movement), a whole section (NOT the whole message) becomes crystal-clear. I have saved many such incidents, but one is below:

I have selected a .WAV file to play on message receipt but no sound! "Default system sound" also doesn't sound . . . .

I tried to attach my "mailcall.wav" but your system wants only images. **Sigh**

I noticed this morning that my Thunderbird tree no longer had a Junk folder. I restarted the program and Junk appeared, with stuff in it, but right-clicking the Junk folder no longer brings up the usual list of options, including Empty Junk. Instead, right-clicking seems to temporarily slow-down or 'hang' Thunderbird, a condition it does recover from in 10 seconds or so. I can open the Junk folder, select all messages and delete them, but something isn't right. Any ideas, anyone?

Update: Realized I didn't mention the version I was running, it was 133.0.3, under Windows 10, but when I opened Help to find this I was invited to do an update... so I did. When the 'update' was complete, I checked and am now running 128.6.0esr (64-bit). That seems strange. Oh, the same Junk problem persists under the 'new' version.

Update #2: Evidently the drop-down menu does eventually appear, if you just wait for it... anywhere from 5 seconds to 30 seconds or so. Normally the right-click is instantaneous. What could have happened, I wonder?

How do I reset the information Thunderbird sends to my email provider (Names.co.uk)? This information has changed as I had to change my password on Outlook (i.e. Microsoft). I used Thunderbird to access this email for many years. So there is an existing account with <outlook.office365.com>. I would like to reclaim access to this account.

see attached. When I right-click on the sender's name, nothing happens . . . .

[also, when I "browsed to get the file to attach, your system ignores all .BMPs. Very frustrating. And, why not allow us to drag an image?]

Today suddenly of my two email accounts, only one was opening when Firefox opened. All my folders were not visible, and the only thing I could see was the inbox for one email account. In the course of my "fixes" it's now even worse. I can only see one old archive folder (I think that's what it is). I tried reading in the forums and questions but nothing helps. I use Norton which some seem to say is a problem with updates, though it never used to be. I know where my stored emails and folders are for both accounts but Thunderbird does not seem to recognize them.

As of this morning, I can only view emails which were received or sent today. Anything sent or received before today is not displayed. I am still able to access emails received prior to today by using the Search function. This only applies on my desktop. On my laptop, emails are displayed normally.

I've used Thuderbird for years; no problems.

Installed 102 on my new laptop running Win 11. After initial download of new mail, it never downloaded new messages again. Tried 115, same problem Tried numerous re-installs of both; same problem.

How do I solve this?

I have added the android app to my phone and tablet but the messages are not synchronising fully with the version on my windows laptop. The 'sent' messages from my phone / tablet do not appear on my laptop although 'received' messages do. 'Sent' messages using the app do not appear in my Gmail linked account either. Any advice would be welcome please, it's a bit of a hassle having to keep checking things on separate machines.

Is there a way to stop Thunderbird automatically marking my messages as read when I delete them to the Trash? I tried stopping automatic marking as read in settings but this makes no difference Thunderbird 128.6.0esr 64bit

I'm using thunderbird: 115.16.0esr on Kubuntu Linux 22.04 LTS and have the same problem as this Archived, yet unresolved problem:

"""When I get a meeting invite, and accept that invite, selecting "send a response now", no message ever arrives at the email of the inviter and no email ends up in any of my folders (drafts or sent). It is like nothing happens. The event *is* accepted and added to the calendar, but no respose is created or sent. """

• I can send a normal Email to the sender of the invite.
• The Email is configured in the calendar

The only differences to the other thread are :

• My Email is hosted somewhere else.
• I use Nextcloud Calender via WEBDAVS, instead of the local calendar
• The invite I receive is created in outlook.

Any help is appreciated. Thanks!

I have a problem forwarding emails from one of my banks containing bank statements to my accountant. I have setup message filters and all is working good for one bank, but emails from another bank won't forward at all. As soon as I run Thunderbird in the morning, I get the blank forward email from that bank containing only subject with my accountant email fulfilled, but no body and no attachments.

Then I have to close that window, and do it manually every morning. I click the received email from bank, than forward, put forward address from accountant and send.

Since yesterday's update of Thunderbird, I cannot even forward email from this bank (inline). The email is totally blank, no body, no attachment. If I select to forward as an attachment (*.eml) than it is all OK.

All other emails forward fine. The problem is only with this bank. Also I have noticed that the digital signature from this bank is not valid, so maybe this is what is creating the problem.
