Owing to a price rise in MS Office, I had been looking to move to free software. Unfortunately for email this isn't working. I have downloaded Thunderbird and have tried to transfer my Outlook data there. I started two weeks ago and on average believe the process has been running a few hours a day, for much of the time when I look occupying 0% of CPU capacity, and most of the time not rising above 1%. The import has been stuck at 33% for that time, which I assume means that it imported Accounts and Settings or Address Books quickly and is taking a very long time to import Mail Messages. (It imported the couple of month's worth on webmail quite quickly.) Likely this is owing to the size of the Outlook file, 5 GB. Does this essentially make the transfer impossible? For how large a file could Thunderbird do a successful import?

Suddenly messages have disappeared from all folders; all I see is No messages found.

I tried Repair Folder. It appeared to work, it ran for several minutes on my Inbox, but that didn't help.

I discovered that if I run in Troubleshoot mode that all messages appear, but when I close Thunderbird and relaunch, which opens without Troubleshoot mode, that all messages have again disappeared.

I'm running 128.11.0esr with windows 10.

Hi - I keep getting the message: Login to account (my email address) failed Login to server imap.googlemail.com with username (my email address) failed.

Can you please help me fix this problem?

I have hundreds of folders; and move an email in inbox to a folder is turns a pain. In Outlook for Mac there is a future which name is Move To Folder... opens by "command + shift + M". Can search inside the folder and can move super fast and easy. I would like to have in Thunderbird and I'm ready to donation again only for this feature =)

Issue 1: When using Shift+F5 to Get All New Messages: This command used to go through my accounts within several seconds; but now this can take several minutes. What changed to cause this?

Issue 2: I have one account that is having server problems... causing must click popups in TB. How do I exclude this account when using Shift+F5? I've tried Unchecking the boxes for "Check for new messages at startup" and "Check for new messages every xx minutes". And one help result suggests "Disable immediate notifications: Uncheck"; but I do not see such a setting.

I have set my account to "Don't delete any messages", because I frequently want to reread a deleted message in my Trash folder. However, when I go into my Trash folder to search for a deleted message, I am finding that messages older than a certain date have disappeared, although I've done nothing to permanently delete them. For example, today everything older than May 3 is gone. What can I do to prevent this?

thanks, CW

Hiya. I had a message that I accidentally deleted by force-of-habit. I found it in Bin and selected Move To/Favourites/Inbox. It's now disappeared and doesn't show in the search. It's not present on my Gmail account either. Is there any way to get this back?

When I delete an email message, they do not go to Trash, they just disappear. I have used TB for several years but this started happening just recently. I can right click on a message and Send To to Trash, or drag and drop, and both those and work. I have went through all the settings I can find, and don't see any obvious problems. I did find a "fix" from 2023 that involved deleting the Smart Mailboxes folder and restarting TB but that that didn't help.

I just pressed Enter and the whole topic disappeared. Why? Why do you do this? This is my whole subject: Why do you do your things automatically, when I try to do manually? You have a great EMAiL-software: Thunderbird. Why do you want to screw it and the user? Computer usage should be reliable. I have lost so many EMAiLs since you broke the EMAiL paths logic with threads. Why? Why did you want to make it complicated? I had a good filing system with Thurnerbird for years. Why did you have to break it? Why didn't you even make it optional, but mandatory?

How can I get the old EMAiL-filing back without the Thread-Paths? Please help!

I didn't ask this immediately, but during the years, I have lost so many important EMAiLs (again today), that now I ask.

We have these "old mail" and "nstmp" folders that will not delete.

right click on Empty Trash doesn't work, need to delete individual emails.

Windows 11

Hi there,

I've recently had a problem with a couple of client PCs where their Thunderbird profile folder has grown to fill the entire hard drive. In both cases, the relevant account folder in the profile's ImapMail dir had grown to over 300Gb. This account takes up 45Gb on the server (where I'm running Dovecot with maildir storage). In another case on both PCs, an 18Gb account had grown to over 90Gb.

Both client PCs are running up-to-date Thunderbird (139.0.2 64bit), one under Windows 10 and one under Windows 11. Both had auto-compact set, with the minimum saving reduced to 100Mb. Both problematic accounts are shared accounts that use a deeply-nested folder structure. In both cases, I was forced to delete and then recreate the these accounts in Thunderbird.

I'm an experienced sysadmin who is also running the mail server, so I am able to provide any extra info needed. Additionally, I accept that these are large email accounts; I'm in the process of setting up an email archive system for the client using Piler. I have read many other reports of outsize Thunderbird data folders; these are usually referring to less than 20Gb. The problems we're having seem to be an order of magnitude larger!

Thanks in advance, P.

I have been using Thunderbird for over 5 years. I am presently using version 128.11.1esr and I update it often. Many e-mails have been put into an "Archive" folder but I just noticed that all of the items put there are now gone. The "Archive" folder is empty. The account that this is attached to is AOL, xxx@verizon.net.

Are there any thoughts on how this could have happened? I am hoping I can get the items back.

Thanks for your thoughts, Steve H.

After working fine for years, Thunderbird stopped receiving email from my POP accounts a month ago and I haven't been able to get it to work since. After weeks of experimentation and frustration, the only way I can get TB to download POP mail is to install and run it in Windows Safe Mode with networking. However, once installed in Windows Safe Mode, TB run in Windows normal mode will successfully send messages from each account.

It would take pages to describe everything I've tried, so I won't. The results of all the tweaking and updates is the system specs below.

OS: Windows 10 Home (x64) version 22H2 AVS: BitDefender Email: Thunderbird 102.15.1 Add-ons: None Theme: Default Accept cookies: Always Exceptions: (added any that seemed even remotely associated with issue) https://accounts.google.com https://mail.google.com https://www.googleapis.com https://pop.gmail.com https://pop.gmail.com:995 https://smtp.gmail.com https://smtp.gmail.com:587 https://pop.centurylink.com https://pop.centurylink.com:995 https://smtp.centurylink.com https://smtp.centurylink.com:587

I'm at a total loss as to what I've missed or where to look next. I would appreciate any help.

Can I find all my emails again please please help me!!!

I don't even know how to explain what happened - I just know this is my booked jobs for the rest of the 2025!! The folders are "greyed out" and it says "0kb"

I see the emails on webmail though - but not my own answer emails and not in folders (= very messy)

I really really don't know what to do!

THANK YOU SO MUCH in advance

I have Comcast as my internet service provider. I use Thunderbird to download a copy of my e-mails from their server and send e-mails out through their server. Until about a month ago, Thunderbird, which I used for many years will not send my e-mails but will still allow me to receive my e-mails. When I try to send an e-mail, I get an error message that says Login to server smtp.comcast.net with username (then my e-mail address).net failed. I had read on Google that Thunderbird was having some trouble and one of the fixes was to uninstall Thunderbird and reinstall it. Also, to check my settings on my computer which I did and nothing has worked. When The message doesn't go through, after this failure message, I then get this message "Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.comcast.net. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'. I tried changing my password and it did not help. I also contacted the Comcast security team which was able to help me with a previous Thunderbird issue but not this one. They said the problem was with Thunderbird this time. Can anybody assist me with this please?
