Thunderbird Support Forum

I'm running Windows 10 Pro (64-bit). I have two different versions of Thunderbird installed on my system; one is installed in Program Files (64-bit version 125.0.0.0 dated 04/23/2024—old version) and the other is installed in Program Files (x86) (64-bit version 115.12.2.0 dated 06/25/2024—the current version). The shortcut icon on my desktop (which I never use) runs the older version located in the Program Files folder while the shortcut icon on my taskbar (and also the one in my Start menu) runs the updated version located in the Program Files (x86) folder.

As an aside, there are 21 .dll files in the Program Files (x86) folder (all starting with api-ms-win and dated 09/27/2023) while none of those files are in the Program Files folder.

FYI, I have been using Thunderbird on this PC for almost five years.

How do I fix this problem so that I have only the current version of Thunderbird run from the proper folder, Program Files?

I have a Thunderbird on my laptop with a big folder in the Local Folder. It has a labeled "mail window" having 5,044 messages in a folder named under the internals of the Profile as "Family" and "Family.msf". Under "Family" are at the next level called "Archive-A" and "Archive-A.msf". (This may not be a kosher "archive".) I tried to use NanaZip to prepare as a zip by Exporting it the other laptop's Thunderbird in our house, but the process seemed to hang before that could do it. Maybe there had to be two levels, I dunno. Maybe getting from a .ZIP to a .SBD....

Even if that had resulted in a useful .ZIP, I'm not at all clear how I could I succeed in importing it into the main profile on the other TB computer. I am defeated at this point.

I wish I had a "Thunderbird for Dummies", or at least a manual + a lexicon with acronyms.

Could someone help me out?

Thanks!

Please assist I have 3 emails address & when I go to send a new email,it does not show up as my default Email on SMTP How Can I Change to that when I send a email,It uses my Default Email on SMTP Thank you Darryl.

When I read an email message, it changes the display from bold blue to bold black in the message list. If I then mark the message as read, the dark black changes to light black. Is there a way to do this once a message has been actually read, without having to mark it as read?

Short background: Critically low on disc space. Windows pointed out a potentially extraneous 8.5gb NS3TMP Thunderbird file. Extensive Googling convinced me it would be safe to delete this file. To be safe (HA!) I first copied it to an external drive just in case things went south. They did.

After the copy, I went back and deleted the NS3TMP file. However, much to my horror, instead of deleting 8.5gb as expected, 30.5gb got deleted. After that, Thunderbird would not start claiming my profile was missing.

I copied the 8.5gb backup file back to its original place. No joy. Same message from Thunderbird.

At this point, I recreated my profile pointing Thunderbird to my Outlook email account.

I could now sign into Thunderbird and T'bird started populating the inbox and sent folders, but only partially. Worse (MUCH worse) my critical Thunderbird local folders were nowhere to be found. I attempted several folder recovery procedures to no avail.

I confess, I do not know how Thunderbird works its magic behind the scenes. Were my local folders part of the surprise 30gb file deletion and thus gone for good? Would the original emails that had been dragged into the various folders still be sitting on Outlook's servers?

As I said, totally self-inflicted but hopeful there's a road to recovery.

Any assistance or consoling words would be much appreciated.

I tried a few times to copy the thunderbird folder from my windows machine to my mac machine but every time I start Thunderbird after that it just creates a new profile folder and ignores the existing one which was already copied. Any help and insight will be greatly appreciate it!

OS: Windows 10 and Sonoma

I started Thunderbird yesterday and apparently did not recognize the profile. It required me to completely set up a whole new account for my emails. Consequently I lost a number of important emails. How can I get it back to my original account? And, for future reference, what is the best way to back up the emails in a manner that PDF or microsoft can recognize the format? Please advise.

My many message filters were lost in updating to 115, and it has taken much time to reconstruct the new layout to be usable. If this was AI generated, it is a poor outcome.

I am considering moving to Thunderbird from MS Outlook. I want the rules I have already setup in Outlook to work in Thunderbird. Is this possible & if so how do I make it work.

When I receive junk email, Thunderbird shows mail received (for example 10 emails) there are ...again for example 3 in my inbox and the other 7 are nowhere to be found. Not in junk and not in trash. I am concerned that there might be some emails that are not junk that I am not able to get. I would like to be able to review the junk folder prior to deletion. What setting options do I need to change to make this happen? I am using pop email... Thanks!!

I would like to remove the newly added listing "Local FOlders" from the Folder Tree and restore the Local Folders listing that was moved to the bottom (below All Folders) to its proper place, namely Above Local Folders. This group displays Sent Copies which I use frequently. The newly added 2nd display called "Local Folders" does not disply "Sent Copies" when I click on it in the folder tree. Thunderbirfd decided to move my original "Sent Folders" display to the bottom of the tree when updating to the latest version last night (early morning hours of 6/26/24). I run thunderbird in Windows 10 Desktop on Lenovo w530 using wired internet connection.

Hi,

I am running thunderbird-115.12.2-1 and Arch Linux and have the following Problem:

- I am using Unified Folders - Online search is disabled - If I change the view in any Unified Folder with more than 1 source folder to grouped by Thunderbird freezes and sometimes crashes - It does not matter what the sort by value is - Any time I switch from a not grouped by unified folder back to grouped by Thunderbird freezes and crashes sometimes again - The length of the freeze depends on the numbers of source folders for the unified folder. E.g. for my Inbox with 11 source folders between 5 and 10 minutes

I already tried - disable all addons - clear the disk cache - set mail.server.default.use_condstore to true - delete global-messages-db.sqlite

https://www.reddit.com/r/Thunderbird/comments/y795od/comment/jwk1kyp/

Right now the group by feature is not usable for me but makes it so much more clearer that I don't want to miss it.

Can you help me ?

Would you please help me permanently remove cache2 folder from Local Folders please. I'm using Thunderbird 115.12.2 (64bit) on esr channel with Windows 7 Ultimate Service Pack 1 OS.

I don't want Local Folders / Cache2 folder (or incidently Inbox, Drafts, Archives, Junk, Deleted and Outbox) but Thunderbird highlight - right click - delete button doesn't get rid of it. I can temporarily delete the Doomed and Entries sub-folders with right click - delete - delete folder but they move to Deleted folder where once again they can be deleted the same way but when restarting Thunderbird they are back under the cache2 folder again.

Even after exiting Thunderbird and directly deleting the cache2 folder(s) in system AppsData - Local and Roaming Thunderbird profiles the cache2 folder (with persistent sub-folders) returns to my Local Folders when restarted.

If ignored I eventually end up having a cache2-1 folder etc.

i have no memory of my password for email ,there are two emails , [edited] @eaglevalley,net and [edited] @gmail.com can you text me answer at [removed] 0r [removed]  ?

Recently I've had problems with the SMTP server refusing to send my e-mails, I am still being able to recieve them however. When choosing to enter a new window the window where you should put your passwords appear and dissapear at the same time. I've never experienced this kind of problems before. I even removed the account and the smtp account and re-added them back again to see if it would help but to no avail.

I am following the article from Mozilla called Microsoft OAuth Authentication and Thunderbird in 2024. But still it won't work.

Hello,

When the primary password window opens and I click Cancel, can that window close AND can it prevent Thunderbird from opening?

Example: what if I bring my pc to a repair shop and they open thunderbird and click Cancel on the primary password window. They can See my previously viewed email. I do not want them to see those. Clicking Cancel AND closing Thunderbird would prevent them from seeing emails.

Could this be a future enhancement?

Thanks

Jim
