When I click on an email, instead of just showing the email, it sets up a Reply screen showing From me and To Me. At the bottom there is an alert: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity......" (lists my email user name and address). Im not clicking Reply, I'm just double clicking the message to Read it.

Running Sequoia 15.7.2 on MacBook Air. It just started today. I have turned it off and on, no change.

The Thunderbird password I've used for YEARS (and is stored in "Saved Passwords") no longer works. I have two laptops with the same password, and they both ceased (on the same day) allowing downloads (or sending) of emails. This occurs on both my laptops -- one has TB version 115.10.1 w/ Windows 10, and the other has 140.5.0esr w/ Windows 11. It also occurs on my iPhone when trying to access the mail server.

Could the problem be the mail server itself?

I want Thunderbird to stop marking everything I delete as having been read. The way it works now, if I accidentally delete mail that I haven't read yet it's much more difficult to find it when everything is marked read even when it wasn't. I searched everywhere and haven't come up with a solution for this. It was reported as a bug years ago and was never fixed.

No longer a Spectrum cable user. Been using Firefox/Tbird for years. Will I still be able to use existing (charter.net/Spectrum) email address via Tbird?

At startup of Thunderbird, get error related to Outlook which I do not use. Get message - "UserHasNoMailboxandNoLicenseAssignedError"

How do I get rid of this error, has been present since last esr release and expected it to go away with new release - did not. Do I have to reinstall Thunderbird to clear.

I've been using Thunderbird on a Windows machine for years. I now have an iMac and recently downloaded Thunderbird to start transitioning over. When I try to set up an existing Email address, the configuration is found in the Mozilla ISP database. After I enter the password though (mobile.charter.net), I get an error stating "Unable to log in at server. Probably wrong configuration, username or password". The password is correct and works on the Thunderbird version on the Windows machine. I have multiple Email addresses and I get the same error on all with verified correct passwords. Any help to correctly install would be greatly appreciated!

Why suddenly has Thunderbird stopped logging my messages that I filter manually even though I have logging enabled? It used to work just fine. It no longer logs ANY message filtering. I have not changed any settings. I depend on it especially to confirm that new filters I set are working properly. How can i fix this?

Hi, I have two email accounts configured to Thunderbird. One stopped receiving emails this week. When I open TB, it's asking password for the account.

Then it shows at the screen bottom xxx@yyy.zz: Host contacted, sending login information.

then after a moment, a popup window says

Login to account "xxx@yyy.zz" failed Login to gamma.yyy.zz with username xxx failed.

Sending emails works ok.

Any ideas ? Possibly a corrupted profile ?

Best regards, Jarmo

This morning when I opened Thunderbird it got all my new messages in inbox but when I went to transfer some to local folders there wasn't any. I probably had about 25 folders in there. I still have email on my older computer and it still works fine. Local folders are still there. What do I do?

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.

Dear Thunderbird support team, I am for a few days unable to log into my account, because the program doesn´t recognize the password I set for the imap.wolrdserver.net. It shows the message in attachment. I changed the password for my account and the imap.worldserver.net with my email provider, however it did not work.

Do you have another idea how to fix this? Thank you in advance. Kind regards Elora Helmke

I use Ubuntu on a Dell Laptop and there is a number attached to the Thunderbird desktop icon on the side-bar which is not related to the number of unread messages?? What is this number about?

Hi I am using Win 10 and update 140. I updated yesterday.

I have been unable to rebuild my Inbox after doing an Inbox repair. It is having trouble staying connected to my email server, imap.comcast.net. The lower left message continually shifts from Sending Login Info, to Connecting to imap.comcast.net, to Connected, to Opening Inbox folder to looking up imap.comcast.net.

I repaired the inbox because all of a sudden I could not open new messages. I would click on them and it would say loading message but remain blank.

I have also had periodic problems with network and file errors. Just before this happened, I could send a message but not copy it to my Sent folder because of these errors.

If I uninstalled and reinstalled Thunderbird would it go back to the way it was?

Should I do a system restore?

By the way I am connected online and at a high speed. so that is not the problem

Thank you Richard Higgins Concord MA

I've been trying to connect now for 12 hours and have only recovered a fraction
