Hello, I have recently been unable to create new messages in Thunderbird. I am currently on the latest version, 139.0.2 (64-bit). There is no Create New Message Button, and Control + N does work either. I am also now getting a lot of extra information in the Header Pane. Refer to the Screen Shot JPG. Thanks, Graeme

Many of my mailboxes on the IMAP server just emptied. They were still there in my Ubuntu '.thunderbird' ImapMail directory. I have created some replacement mailboxes in 'Local Folders' and copied mbox files from the ImapMail area to the Local Folder area, removing the .msf files just created by Thunderbird. I then used the Properties->Repair Folder on each of the the new Local and filled-in-the-background mailboxes. Many worked fine and I was able to repopulate the IMAP server mailboxes using drag in Thunderbird. Some, however, were mis-parsed, producing 'From-less' and Subject-less messages containing part messages. Thunderbird seems unable to reliably parse mbox files created by itself. I note that they are not strict mbox format, having a '-' instead of an envelope address on the delimiting '^From ' line. (I am a retired Unix SysAdmin, so used to the command line)

Since yesterday Thunderbird cannot download messages.

It says "Downloading 1 of 4 messages" and attempts for a while, then stops. No messages are downloaded.

On both MAC and PC versions. I recently installed a new SSL certificate on one of our company servers. It works on most email applications without issue (Apple Mail, Outlook etc.) - but Thunderbird is complaining about the certificate. The certificate is coming from: sectigo.com

The error is: unknown identity The certificate is not trusted because it hasn't been verified as issued by a trusted authority using a secure signature.

If I confirm the default exception - it uses port: 443 - instead of ports 995 and 465.

A certificate exception has to be deployed by adding network.security.ports.banned.override to the configure editor. Adding a string of 995 and then 465 to make the exceptions. It doesn't always work....

I have used multiple online scanners and they all give green lights on the certificate. Any help appreciated... I have no idea where to go from here.

Hi everyone.

Hoping someone may be able to help. I see that other users are able to fully highlight the events in calendar. I seem to be only able to highlight 2/3's (see image)

Thanks in advance

Has anyone had this problem where the headers download but you CANNOT see the contents of the email? If so, has anyone found a solution to being able to see the contents. Centurylink email support is a joke.

GOAL: I am trying to get off of Centurylink but I have lots (OVER 20 years) of important (health and support group related) emails (thousands) that I would like to retain the full contents to and move the mail to my live.com account. I figured out how to set up the other account on Thunderbird already but can not get the full email on my primary Centurylink (Q.COM) account to download. I think I configured the download options correctly but am not sure. See attached.

Thanks in advance!

I have used Thunderbird for years on my desktop computer with a gmail account. I have many "Contacts" in my Address Book.

 I recently added Thunderbird to a new laptop computer.  The laptop Thunderbird does not "see" my contacts or address book.

. . . . I am not going to re-create my entire Address Book in the laptop by re-typing thousands of contacts!!!!!!!

I recently upgraded to new software for Thunderbird. For some reason now, when I click on New message, it doesn't work. I can't write a new message and therefore I cannot do my work as I need to.

Any assistance would be greatly appreciated.

Thank you!

Hello, I want to delete all incoming gmail messages. I have set up a filter but instead of deleting them it puts them in the Trash folder.

Is this the expected behaviour?

I get the following error when trying to delete emails:

Messages cannot be moved or copied because writing to the folder failed; to gain disk space, go to file, empty trash, then compact folders.

I have tried this and all trash folders are empty, yet the message remains, I cannot delete, move or receive emails. There are 970 emails in my inbox... I even rebooted several times after doing the above and it still does not work.

What ever instructional help is provided, please include how I can save some of those emails if possible as I don't want to loose them... Right now I have had to go to spectrum to be able to read any incoming emails. Thunderbird is bricked....

Please help...

Thank you

Cannot delete e-mails from inbox. Cannot move them to Trash. Will copy only a few into trash and not remove them from the inbox. Emptied trash, compacted inbox. Read your suggestions, not help. Using Windows 10, latest version, Thunderbird 139.0.2.

I set up a sub-folder to my INBOX. Named it PRIORITY INBOX. Used message filters to send 3 e-mail addresses to the new inbox. It worked, then something changed and it stopped working. Incoming messages from those 3 addresses don't show up in PRIORITY INBOX. They also don't show up in INBOX or JUNK or TRASH. They don't show up anywhere I can find. Then I deleted all three filters, then deleted the PRIORITY INBOX. Now no messages show up anywhere from those three addresses. HELP!

Until recently the search message function displayed a count of the number of finds down in the bottom left hand corner of the screen. Now the number flashes on for a second or two and disappears. To know the results of a search now, I have to sit and watch until the search is complete otherwise I have to way of knowing how many were found. Has anyone had this happen and found a solution?

Hello Following a recent thundebird update, the body of certain emails contains a list of links to images rather than the images themselves that appeared before. The screen looks crowded, confusing and unattractive. How can I revert to the old, much more attractive appearance ? I have searched but can find no help. Regards

Ich kann keine Nachrichten mehr erhalten und und kann auch nichts mehr absenden. Es wird immer wieder ein Passwort bzw. neues Passwort verlangt, das war all die Jahre nicht. Auch ein Passwort wird nicht angenommen. Hab schon alles ausprobiert.

When I try to forward an article (to myself or others), I get a message: "Do you want to allow this app to make changes to your devices?" Whatever button I click on, it goes into Set-up mode, though it's already set up on my PC, and getting out of the sequence is difficult, like navigating blind alleys to nowhere.

Local folders were in default location on C: drive, 128GB SSD boot drive. Installed a 1TB SSD as D: drive. Want to use D: for local folders. When changed local drive to D: lost access to default Local Drive. Can't reconnect as location not visible in file explorer. Want to move local folder from C: to D:.
