Can anyone tell me how to set up the THUNDERBIRD TO ALWAYS LOG-IN into its own Messenger and avoid the Yahoo's interference with his INADEQUATE Messenger format - this should not be high-science question but I have difficulties to find an information in the HELP-section - thanks, Tony H. ...!

Thunderbird has worked great for me for years, up until a few days ago. Currently running 137.0.2 and am encountering two problems. I have several emails and this has not been a problem in the past.

Now, I start TB and all works fine for minutes or an hour or two and then some inboxes start to display "No message found". If I close TB and restart it all is good, but noit for long.

The other issue which pops up is

"The folder '[Gmail]/All Mail on XXXXXX@gmail.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I have over 200GB free on the drive.

Thanks for any help solving this!

PS Win 10 Pro, so maybe time for me to upgrade to Win 11 which I plan to do in the few weeks anyway.

For the past week or so, I've been getting the following message every time I open Thunderbird.

"The folder 'Outbox on Local Folders' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

Also, the folders appear to be empty, but the eventually repopulate. I have plenty of disk space and haven't changed write privileges. A Google search doesn't turn up any solutions. Can anyone help?

Hello, 1. This is Sheila Herman again. I'm having problems with my other computer. I have two accounts: Harry's (herman.harry@twc.com) and mine (swherman@twc.com). When I tried to send an email, this message pops up: Login to server mail.twc.com with username swherman@twc.com failed, and I can't receive messages too! 2. There is only 1 Outgoing Server (SMTP) at the bottom of the left pane, and should there be 2? I would be grateful if someone could help me solve this annoying problem. Thank you so much and I look forward to hearing from you. Best regards, Sheila

Hi- Some emails just don't show up in my inbox-I can get those emails on my phone (applemail) or webmail but not in my thunderbird on my mac. They do not show up in junk or trash. it is like they never existed. How do I fix this? Thanks

I am using ThunderBird, and when I mistakenly sent to the wrong recipient, I did not receive an email indicating a sending error (bounce). It is not in my spam folder or trash folder. What should I do to receive emails indicating a sending error?

I used to love Thunderbird but now i am having problems with it why is it doing this please i do not wan to remove it forever but this happening why every inbox message has my name as sender and receiver ii m so confused and has a yellow line underneath i need to have someone help me please i am begging please explain idid use cccleaner an glary and aftet this is what i got not sure i can un do it

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?

Compacting fails with error message " The folder 'Inbox on **********' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again." This happens on both my PC's, which are not connected in any way, but have duplicate installations. The profile is 7.75GB - PC A - Win 10 Pro - has 704GB spare disk space, PC B - Win 11 Pro - has 50GB spare disk space. I can think of no reason why write permissons would change. This problem started with ver. 138 & has continued with ver. 139

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 need to find appointments in my Calendar...however, when I open the "Find", it only allows messages and contact searches. Is there another way to search the Calendar?

Thank you, Nancy

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.
