Hello everyone,

I hope you're doing well. I often find Thunderbird's search function challenging to use, and I'm not sure if I'm doing something wrong.

For example, I recently searched for "<company name> shipped" to locate a tracking number, but even though the email contains all these terms, Thunderbird doesn't display it.

Is Thunderbird's search function really this flawed? Have any of you found tools to make it work better?

Thanks in advance for any help or for sharing your experiences with similar issues.

How to completely reset Thunderbird preferences except for configured accounts? I mean all visualization preferences, menus, themes, buttons, whatever. But don't touch e-mail accounts.

With the latest Thunderbird update (128.1.0esr) I am seeing frequent "not responding" situations. It eventually does come back. Am I doing something wrong? I am on a PC running Windows 10.

I like customizing everything, and when i used Outlook, when i rightclick on a email i could chose immediatly to send that mail forward to someone.

but in Thunderbird, i get :

mark as unread - answer - ( here would send forward be nice ) - archive - marks as not wanted - delete.

is it possible to change archive to , send forward :)

not a biggy, just if someone knows how to do it.. that would be nice :)

My isp is virgin media and I use Mozilla for browsing and emails. I have been with them for many years but recently I found that although I am receiving emails I can't send them . I get this message.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Authentication Required (VM401). Please verify that your email address is correct in your account settings and try again.

After an update to Thunderbird around 8/10/24, I can still list future calendar events, but no longer past events. It is very useful for me to list past events. For example, I can quickly find out when I last had a flu shot. Could you restore this ability to print a complete list of past events, as well as future events? Thanks! Carl Lund

Hi, I'm new here and need some help. I use gmail as an email client and I want to use Thunderbird to save all my emails there. But when I delete them from Gmail, I want them to remain in Thunderbird and not be deleted from there. How to prevent the deletion of messages from Thunderbird using Imap? If I use Pop3, messages from folders or sent ones do not appear, that's why I use Imap, but when I delete messages directly from gmail, I see that they are automatically deleted from Thunderbird as well, how can I prevent this from happening again? Thank you very much, take care!

I am using Thunderbird on Windows 11 and I have foolishly allowed it to update itself to release 128.1.0.esr without checking the bug reports first. Now it turns out that this release removed the possibility to search the calendar for past events, which is absolutely essential for me. There is a Bugzilla entry for this but it is bogged down in discussions about who needs which date ranges to search in and how many instances to show for recurring events, so I don't expect a solution any time soon. How can I revert Thunderbird to the last release which still has that functionality? I have regular backups of my userprofile folder in case it helps.

I am trying to setup my ka1vrf@bellsouth.net account in Thunderbird Mail. I have been reading a number of threads that say that this cannot be done, but a number of these are old threads, Has there been any changes and/or is there a way that I can setup my bellsouth email to forward to my gmail account?

Hello,

I have had this issue since at least 2022 starting with version 102.4.1. I am currently running 128.1.0esr on OS 14.6.1.

I figured I would post again, as it has been a few years and the previous posts are now archived, to see if any new solution options are known.

In short, Thunderbird runs perfectly fine in troubleshoot mode. When launched normally, it locks up as soon as it checks for new messages, I get the spinning beach ball, and I have to force quit to close it. Letting it sit for an extended time has no impact. Screenshot of status when it locks is attached.

If I start in Troubleshoot Mode it works normally. No problems at all. I don't appear to have any add-ons or extensions running, so I don't understand why this is fixing things. I've just been running it in troubleshoot mode for years now, which is fine, but annoying.

The only themes, extensions, or add-ons present are "light," "dark," and "system theme -auto." Nothing else.

I had read a previous post about disabling access to Contacts in System Preferences, I tried that, no luck. I also deleted all add-ons and extensions files, and folders. Folders were empty, no change.

Any other theories?

The latest rev is VERY slow (several seconds) compared to prior revs to process email changes within INBOX (OPEN, MOVE, DELETE, etc.)

Something new is going on internally to the program while the hour-glass appears for a few seconds more than before (I did not change any settings w/ latest upgrades).

Dear, I'm trying to clean up my massive mailbox by deleting email messages from the "All mail" view in Thunderbird. Despite settings like "Immediately delete" and "clean up (expunge) inbox on exit" and "empty trash on exit", the emails always come back to my thunderbird client.

When deleting directly on gmail (eg. in accessed through chrome) the mails remain deleted - also in thunderbird.

What can I do to avoid the need to redo the action over and over again, and eventually having to abandon thunderbird in favor of working with gmail online?

Best regards, Pascal

Why do mails disappear out of sight when I have read them. I only can see the unread mails in Thunderbird.. I have to go on the net to my one.com-mail to find the mails I have read.

The latest update to Thunderbird did all sorts of damage, but the attached image is one. My emails now look like they're a jumbled mess of code. Is there a way to reset or refresh these so they actually show the email?

I use Mozilla for incoming mail, but cannot get it to send mail out. I get an error message to check my SMTP settings, which I have done repeatedly, and it doesn't fix the problem. I use those same settings to send my mail OUT with webmail (which is inconvenient to have to switch all the time), so I know the settings are correct. Can you help me understand why my outgoing mail won't work even when I verify that the settings are correct.

I recently bought new Dell Inspiron and loaded Thunderbird as I have used elsewhere for very many years The folders are threaded which is usless for the way I work and I want to permanently disable this preferably in one action as I have many folders

Advice how to do this would be appreciated

Many thanks John Puncher

Debugging message filters and want to see the log. From message filters window I click box "Filter Log". It brings up the small config box of which a pic is attached. I can't find anyway to actually see or access the log. It must be hiding here somewhere ? ?

I have tried to clear the log so it is small in case it is large and takes long to load as I've seen elsewhere. No change.

I try to look this the "Activity Manage" which has some log like error messages but it is a mess of unordered seemingly random successes and some failures. This is another topic.

So, any guidance on how to use the filter log would be greatly appreciated.

A few times now I've had a batch of incoming e-mails where the date, sender, header information are all there but the body of the e-mail shows: FXCG9w89iTyF8D70T5uihi9D instead of the message. I don't know what this means or why it happens. Can you explain and help me find a solution?
