Thunderbird Community Forum

After deleting a large number of historical emails, including emptying the Deleted items folder, and emptying the Archive folder, Thunderbird restores a large number - but not all - previously deleted emails. Oddly the emails that are restored to the inbox are only ones from 2022. I have gone through and deleted them multiple times but they keep coming back. Any suggestions? Thanks, Simon.

I have just installed Norton 360 but am not able to receive emails. I followed all the steps as outlined in the Norton help site as much as possible and Thunderbird tells me that wscert.der is installed. However it was all to no avail. When doing so I did not see the screen asking me to trust this CA to identify web sites but every other step seemed OK.

I would like to change my main e mail from [email1] @manx.net to new one [email2] @gmail.com, also so some icons have changed to lilac and I cannot open those can you please help .captions attached

          Thankyou John

Email messages which contains items other than plain text used to cause a button to be displayed that told me there were items other than plain text in the message and asked if I wanted to display them. Suddenly, that option no longer appears on individual messages. I don't know of anything I did to disable that function.

Looking carefully at your documented instructions I have every setting correct except in the outgoing SMTP server I can select connection security to STARTTLS but i do not have the option available for OAuth2 in the drop down list for Authentication?? What do I do as I have updated Thunderbird to the most recent available for my 32 bit version of Linux which is 68.10.0 which it appears cannot connect to my Hotmail mail service. I do have OAuth2 available on server settings strangely enough but not in outgoing SMTP server settings.

1. I am getting Mozilla Thunderbird ESR notices pop up when I log on to my PC (W11). I checked my Thunderbird version and I have 146.0.1 and I am on the release channel so why am I getting these notices ? 2. Recently I noticed that when I try to move e-mail messages to a specific folder, I right click on the message and get the prompt Move To and then Recent Destinations where the problem exists. The list of Recent Destinations used to be in alphabetical order and now it is sorted by most recent destination time. This slows me down considerably. Please revert. Thanks !!

The File (saving to a folder) Recent function used to have the folders alphabetically. Some genius thought to reorganize the Recent folders to be in chronological order. Is there a setting to have the Recent folders be in alphabetical order again? I could not find anything. Thanks in advance.

When I open Thunderbird now I suddenly see a whole load of 'Recent Folders' at the bottom of my All Folders list.

All of my folders are suddenly all over the place. Please can someone help?

"Your Thunderbird profile cannot be loaded. It may be missing or inaccessible" keeps appearing mid-screen. version 147.0.1 re-installed several times (Win-10). Transfers of profile attempted from operating PC (Win-10) Cannot locate profile even in a "fresh Install" although the shortcut appears on screen and other associated files seem to be installed. Helps have been downloaded and tried. Same issue. I've received help suggestions from Lin and sfhowes both on 2-6-26.. Thanks for your help.

I use the "move to" function to move emails from my Inbox to various other folders. I use the function on a daily basis. Since the last update, when I click on "Move to", the Recent list is no longer alphabetized. This is very frustrating. When will the alphabetization be returned?

I used Thunderbird for many years, but starting in August 2025 it stopped working. It was getting an error in the smtp server, and I was unable to resolve that issue. When I try to login to Thunderbird now, it tries to send a message to pwrichcreek@twc.com, but that no longer exists. Thanks for your help.

For the past few days when I open Thunderbird I get a message "https://caldav.one.com is requesting your username and password." (see attachment). I've never signed up for Caldav so I don't have a username or password. If I hit "Cancel" it proceeds as normal. If I enter my email address and log-in password it also proceeds as normal. In either case I have to go through the same process every time I open Thunderbird.

Hello! The other day everything worked as usual, and I shut down the computer for the night. The next morning, Thunderbird immediately crashed/shut down when starting each of the 2 profiles I always use. The 3rd profile, which is the default-release running a different email, still seems to work normally. Thunderbird 115.10.1

I have tried Windows (10) safe mode, as well as thunderbird Troubleshoot mode and working offline, but the issue continued to occur.

I'm at a loss now as to what could cause 2 profiles to suddenly cause it to crash. By the way, one profile is for a gmail account and the other one is for an Outlook account, so they don't seem to be related.

In case it helps, there were 2 Microsoft Visual C++ programs installed or updated, and updates to Microsoft 365 and Google Drive just before the problem started. These were all auto updates in the background.

Any help from the Community would be greatly appreciated. Thank you!

Hello! I want to set up TBird to: 1) Get all my messages and attachments stored locally, and... 2) Remove *most* of the above from gmail's server to avoid the data limit, but... 3) Keep, perhaps some months or a year of activity on gmail's server so I can access recent items from wherever.

Questions: 1) I have 10s of thousands (more?) of msgs, many with attachments. Is it better to just set up TBIrd and let it grab all the messages, or start by using Google TakeOut? 2) I presume I use IMAP vs. POP? 3) To preserve messages on my harddrive, I could archive to a local folder. Then I could safely delete those same messages on the gmail web interface? 4) If this turns into a disaster, can I just remove the entire account from TBird without suffering a loss of my entire email history? 5) Any insurance maneuvers to prevent the disaster of accidentally losing my entire email history while attempting to set this up? (Obviously will need to be religious about backing up my own system, though keeping a year of email on the gmail server offers a bit of insurance once the set up is successful.)

I am really hoping to avoid creating a unholy mess of my email/spending a week trying to fix it. (Indeed, I have avoided this project for years for this reason, but I really, really want to do this.)
