Thunderbird Support Forum

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

Trying to all threads to come up when I click on a new email as a default. Already did this:- settings>general - scroll down to config editor - enter mailnews.default_view_flags and change value to 0. Does not work!

We have recently moved to a new mail server. We currently have about 20 Thunderbird email clients on Windows in an office location and a macOS home machine. On all machines email is configured to use IMAP on hostname.com port 993 SSL/TLS with Normal Password and SMTP on hostname.com port 465 SSL/TLS with Normal Password.

The home machine is working 100% with no issues, it does have a much faster and lower latency internet connection than the office machines.

Many of the office machines are experiencing intermitent SMTP error messages when sending, intermitent, "unable to save mail in the Sent folder of the Inbox", messages and intermitent unable to move messages between folders.

I have checked and double checked the settings on affected machines - however, I believe a settings issue would result in nothing working, not intermitent functionality. Plus all is working fine on the home machine with the same settings (different OS, but ports and security settings all dictated by server).

With one client behaving properly, the server likwise behaving properly when addressed by the working client and the intermitent nature of the problems we are finding, I suspect we have some sort of network issue. Somthing timing out or a firewall/AV software causing a delay.

I have increased mailnews.tcptimeout on affected machines to 250 based on a forum article but this has had no effect (No idea of units here but if it is seconde then I am not supprised - the SMTP errors, when they happen are almost instantanious).

Any ideas on how to trobleshoot this problem further - The problem seems to get worse through the day, although that may just be peoples tollerance of an intermitent issue going down.

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 keep getting the attached error msg when trying to send an email. I've changed it to "Normal Password" as advised, but it's still the same. Any help would be appreciated. Regards norman

my emails for my Spectrum.net account are not being received as of 6-24-2024. other email accounts still work OK. How does this get fixed?

I would like to know how I may transport Thunderbird from an old computer to a new without losing data. The old computer still is working. I do not have gmail, though I am considering going over to it.

Note: For some reason, I cannot check the box below, requesting that I receive an email when someone answers the thread. Please email me when someone answers the thread.

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.

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 ?

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?

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!

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.

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.

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.
