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

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

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

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 =)

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. ...!

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.

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 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 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 converted to Thunderbird 128,11.1esr in May 2025. My address book did not migrate to the newer version and I don't have the old one. Also, I don't know how to return to the previous version of Thunderbird.

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.
