Thunderbird Support Forum

A while ago, I had to work offline so I had TB download my Gmail account messages. Now I no longer want these messages to be stored locally, because the Thunderbird folder is up to 10Gb, so I unchecked the box in Synchronization for 'Keep messages in all folders for this account on this computer'. I was hoping the TB would subsequently purge the offline folders, but apparently not. Is there a way to clean out the folders without affecting my online Gmail folders as in Inbox and Sent folders?

I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

Previously, for years, selecting and deleting groups of emails took only seconds. For sometime now, the more emails selected to delete as a group causes the amount of time to do so to become longer and longer. Minutes go by. It feels like instead of dealing with all of them at once, it's deleting one at a time, but that's just a guess. What can I do to get back to where it used to be? Thank you.

Since applying update 115.10.0, Thunderbird will not close correctly and will not relaunch until task is ended in task Manager. This is true on a windows 7 PC and windows 10.

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

The message field is too narrow for all messages, except pure text messages. A screenshot is attached. How can I modify the userChrome.css so that all available space gets used?

Since the latest thunderbird update 115 I have multiple crashes & black screens, before this it was very stable. I have been using this since 2015 I think with little problem until now. If nobody else is having problems with 115 perhaps I should just use windows restore to go back to Dec 10th 2023. The only alteration to settings I made to try and fix it was to untick "use hardware acceleration when available". It made no difference.

Apparently the latest Thunderbird update is causing our Windows 11 print spooler to stop. I've seen this problem talked about elsewhere but have not seen a solution. The spooler has to be restarted, otherwise no app/program will print, since only Print to PDF is then available. This is making Thunderbird almost useless to us. Help.

Thunderbird is using 20-25% cpu and is very sluggish. (This is a relatively new problem - within the past 4 months).

I have two gmail IMAP accounts and one POP account. All show about 30-40K messages. I am working on deleting messages from the servers and local archiving thinking that maybe the problem is with synching or compacting(?). Anything else to focus on? Is there a way to tell, or place to look for what is consuming so much cpu?

Re-running in troubleshoot mode with add-ons turned off does seem to help a little, but it's temporary.

Thanks

Shortly after a recent microsoft update, Thunderbird stopped working entirely. No downloads from gmail, manually or automatically, I can't send emails either and I get an endless message that it's trying to copy the outgoing email to the Sent folder (I think), but it never actually does it, and the message never goes out.

I've gone through a bunch of the suggested fixes from various forums and checked the settings. The only one that was different from the recommended settings was hardware acceleration, which I turned off.

I'm at a loss. It won't even download manually when I hit the button for "Get Messages."

Any help would be greatly appreciated.

Thanks

Howdy, I have a number of folders under my POP email account folder. I moved a couple of them to the local folder using drag and drop. It seemed to be going OK but when I went to double check the content, all the messages where gone. I could not find them in trash nor were they in the "from" or "destination" folder. The only things that were saved were the folders and subfolders.

This seemed like a simple move operation but it has gone very wrong. Any ideas why?

I have backups. Can someone point me to the procedure to recover specific folders in email?

I have been trying to search for a solution but have not been successful in even finding this issue.

This is on a Win10 PC running 115.7.0 (64-bit) version of Tbird.

Thanks!

Hello, I'm using Thunderbird (and before Netscape Messenger) already 30 years. With this new version 115.4.1 (32-Bit) I'm now experiencing the symptom, that, when I reopen one of the mailboxes the focus is not in this mailbox on the last read mail as it was always in earlier versions, it now focusses somewhere so that you always have to scroll to the point where you have been last time.

I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)

Thunderbird will not open. the error message is: "Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window." Pressed the "Close Thunderbird" button, but no response. Checked Task Manager and ended the Thunderbird application...still no change. Uninstalled Thunderbird and downloaded .exe file and installed...still the same error message. Rebooted the computer...still not change. Can you please assist with this problem. Thankyou I
