I understand the basic differences between unread folders and unified folders what I don't understand is why two of nine my accounts are listed in both unified folders and unread (see circled in red) how do I remove the two accounts from unified folders or

add more to it
and what makes it confusing is that the subfolders aren't the same when listed in unified or unread

Today, most of messages have suddenly disappeared from my TB inbox, leaving only the most recent 105 out of approx. 18,000. I have not performed any operations (compacting, archiving...) that could have caused this.

I immediately invoked the 'Repair Folder' command, which did not resolve the problem. Further investigation revealed that the 'Inbox' file ('Profiles' folder) actually contains only 105 messages - seems like the 'Repair Folder' truncated the file!

Fortunately, all the messages are still on the server. My question: Is there a method to 'force' reloading of the missing messages?

Thanks, Ray

Just switching between inboxes can cause up to a 10 second delay with Thundebird "not responding" with the spinning wheel. It has been like this for the last few laptops I've had and through all the updates and I am getting ready to call it quits. I did a performance recording of me just clicking through the different folders and then it locks up on one. You can see it here https://share.firefox.dev/3WlrRi9

I am using a primary gmail imap account, an office 365 imap account, and another imap account from an ISP.

On Win 10 LTSC, CPU: 16 x 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz @ 2304 MHz 10240 KB Cache, MEM: 65277 MB, 60% (39120 MB) free, GFX: NVIDIA GeForce RTX 3080 Laptop GPU 16192 MB

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.

Hi 😊 I’m trying to resolve my sisters’ issue with Thunderbird, and I know nothing about Thunderbird. When I open Thunderbird, I have an issue in that the Archive folder is there but no content is shown

Yet if I go to where the files are they seem to be there. They were working but I accidentally deleted the folder and out of the trash folder as well. If I go into “C:\Users\Sue\AppData\Roaming\Thunderbird\Archives.sbd” where the emails and folders are, they seem to be there but not showing in Thunderbird when I click on any folder in Archive and are appear top be very small, i.e. empty.

I have screen shots if you require but thought not appropriate at this stage.

I have 6 accounts on cox.net and today in two out of the 6 accounts, emails that I send are not saved and I get a message "Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. The "sent" folders for these two accounts are grayed out. I have verified that the account settings have the right folder as the destination for the sent emails and have checked that all emails should be saved. I also get a message in Thundebird -The current command did not succeed. The mail server for account xxxxx responded [TRYCREATE} Mailbox doesn't exist. Mail goes out but no copy is saved. Only two out of 6 accounts are affected and I didn't do anything to them before this started happening.

Using windows 10, windows firewall, windows antivirus, Thunderbird 115.9.0 (32-bit)

Can't send from Optimum accounts.

Error message "Sending of the message failed. An error occurred while sending mail. The mail server responded: Spam detected by content scanner. Message rejected (ID 661FD756017B2BC6). Please check the message and try again."

Check outgoing server setting, tried changing authentication method, but got the same error.

(TLDR; Questions in bold at the bottom)

I currently have just a desktop Mac. I recently switched from Apple Mail to Thunderbird to read three email accounts: iCloud, gmail & a university account. I had previously used rules at the server level on my iCloud account, and this caused hella pain during the migration, including some zombie rules that I think I have isolated to Thunderbird. I deleted the rules from iCloud, removed the iCloud account from Thunderbird, restarted and then re-added it to Thunderbird. So far, so good, although I had to resubscribe to the draft, junk and trash folders (all other than the inbox) for some reason.

I have decided to experiment with not using rules or folders at all, and instead use local saved searches in Thunderbird. This will make my life easier when I get a laptop, which is inevitable. Two machines reading the same IMAP emails with rules can get weird.

Can I copy/paste existing saved search folders, so I can do similar searches just by making minor changes to the search terms? If so, how?

Can I copy/paste or save saved search folders, so I can do the same searches on a different Mac, without painstakingly recreating all the search terms? If so, how?

Can I create a saved search folder that contains all the messages not found in any OTHER saved search folder? If so, how?

I'm trying to migrate Thunderbird from my old PC/Windows 10 to my brand-new PC/Windows 10, following the step-by-step instructions on https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer. I followed those instructions to the letter (multiple times) but can't get it to work. Are there more recent (and perhaps more complete) instructions to be found elsewhere? Does anyone else have the same?

I have made a copy of my old TB profile folder on a backup stick (it is titled 'Thunderbird', and inside that folder is a folder titled 'Profiles' that contains a number of folders including the most recent profile that I am still using with my old PC. The difficulty is getting this backed up profile info installed on my new 'destination' computer.

Any suggestions would be greatly appreciated.

Hello. I have my outlook.com account set up in Thunderbird 115.10.1. When I delete emails in Thunderbird from my inbox, they disappear and they go to the Deleted folder in Thunderbird as they should, but they aren't deleted on the Outlook server. I can still see them in my inbox if I use my Outlook app on my phone. I must delete them using my phone.

If I delete an email on my Outlook app on my phone, they disappear immediately in Thunderbird, which is correct. In other words, it works correctly if I delete from my phone, but not from Thunderbird.

My server settings are: Server Type: IMAP Mail Server Server Name: outlook.office365.com Port: 993 Connection security: SSL/TLS Authentication method: OAuth2 When I delete a message: Move it to this folder: Deleted on <myaccount>@outlook.com

Can anyone help? Thanks!
