Kinda confused. Why, when I enter the unified folders, is the INBOX show empty when the ALL FOLDERS shows 6, indicating that, indeed, messages SHOULD be there? See attached.

I have recently lost my "All Mail" folder, and have read the previous solution to highlight the account, right click "Subscribe" and then click the "All Mail" box. My "All Mail" box was already checked! What can be done to restore it since it was checked all along?

We have about 40 people still using Thunderbird with Exchange Online. One person is seeing many empty grayed-out folders and subfolders in Thunderbird. If you try to delete them, they come back. If you try to unsubscribe the folder, it comes back. They persist from client to client, computer to computer. Logging directly into Exchange Online using OWA does not show the folders. Unchecking "Show only subscribed folders" causes them to disappear." But they still show up if you right click on the account and click Subscribe. I have already opened a case with Microsoft and they say it's a client issue and not an Exchange Online issue.

I am getting frustrated that I keep getting multiple folders with the same name. When I save my emails to a local drive I use ALL MAIL to save and retrieve. Now I don't even have the ALL MAIL folder! Vern

Just deleted all the files in my archive folder which also deleted all my inbox files, why has this happened ? I don't want an Archive Folder. Have tried to remove it by unchecking box in Account Settings, Copies and Folders, this does not work . I have lost everything in Inbox, and Sent. Brilliant Result from something I do not need and did not set up.

I have a number of email accounts in TB. Everyone of them have an archive folder. Most are Gmail accts. All of the Gmail acct archive folders are filling up with random inbox emails that I did not archive. The one none Gmail account is not. My archive folders on Gmail only have the emails I have archived. Why is this happening????

Get this error message I think since the update on September 2nd. See below

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox. Also, I downloads a few old emails from September 2. If I delete them, they re-download when I click on get mail. I do get mail on my phone and on the Xfinity web site. I really would like to get this fixed as soon as I can. Thanks, William Dudzinski - <redacted>@comcast.net - <redacted>

Unable to add my Mailfence email account to Thunderbird deb install on Ubuntu 24.04.3 Set Up Your Existing Email Address in Thunderbird returns " Thunderbird failed to find the settings for your email account" yet my web mailfence is accessible

I really don't know where to go, but I hope you can help. I do realize that when two products are involved it is 'THE OTHER GUY causing my problem. I've encountered it in the past. I use Mailwasher Pro to preview my incoming mail. It marks some important mails as Comcast/junk. I delete the real junk and leave those on the list of mails I want to download, and decide whether those are worth keeping (many are) after fully reading them. Thunderbird bypasses these on my incoming mail list. It seems to me that if there is mail to download, Thunderbird should do exactly that. How can I manage this, please?

I am unable to send emails because i get an error message :"sending message failed, because connection to outgoing server (SMPT) smpt,centurylink,net timed out.

I recently installed Thunderbird for use with Gmail. I have created several message filters, but they keep disappearing. I have found that multiple filter files have been created:

Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\ImapMail\imap.gmail.com 2025-10-28 22:30 385 msgFilterRules.dat

              1 File(s)            385 bytes

Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\Mail\Local Folders 2025-10-28 19:07 241 msgFilterRules.dat

              1 File(s)            241 bytes

Directory of C:\Users\shrdl\AppData\Roaming\Thunderbird\Profiles\ae352sn6.default-esr\Mail\pop.gmail.com 2025-10-26 11:03 0 msgFilterRules.dat

              1 File(s)              0 bytes

Any idea why this is happening? Thanks

Namely, that my antivirus program quarantined the entire inbox file upon detecting malware embedded in a single message.

So I encourage people who encounter this issue to explore that as a potential cause.

Thanks to those who responded for the help and patience.

I used to be able to see a running account of the number of messages left to move or to delete.

If this is still available, how do I turn it on?

Thanks.

My emails sent folder has 485 messages. Is there a way to delete them all at once instead of individually?

Also how do you check for new email if you're in the program. I have been shutting Thunderbird down and then opening it back up. Is there another way of doing this?

Just opened TB. There were 8 or 10 emails. Went to another app for a few seconds. Went back to TB. Emails were gone. Have NO idea what happened. Know of any way to get them back or where they went?

I'm a long time user and supporter. All of a sudden I can no longer send messages. After completing the message and entering info, there is no "SEND" in the upper left of the screen so the message can not be sent??????? Could use some help...............................
