When we first started using a third party application to track our customers information & jobs; we received emails showing the customers name on the correspondent/from column. Now all of the emails show the third party applications name and I do not know which customers are trying to contact us.

Last week I started getting the attached pop-up

I don't use Calendar on Thunderbird (as it does not sync ) Not sure why this has started ..... I have tried putting in password and ticking the remember box - but it still keeps popping up.

I can not get my google workspace account to authorize in Thunderbird. Using IMAP setting. Thunderbird automatically finds the correct server settings, but when I hit "continue", it gives an authentication error.

I have spent extensive time with the google workspace admin console help. This is the final result: "Thank you for trying all the steps so far. Since Thunderbird has already been added under App Access Control in the Admin console, IMAP is enabled, and cookies/cache have been cleared, but the authentication error still persists, this points to a possible issue with the application’s client ID used by Thunderbird for OAuth. In this case, you will need to contact the Thunderbird support team to verify the correct client ID for their OAuth implementation. Once you have the correct client ID, we can then configure it properly in the Google Admin console so the authentication works successfully. We’ve confirmed that all Google Workspace settings on our side are correct, so the next step must be coordinated with Thunderbird’s team."

Therefore, here I am.

Hello. Some email addresses are no longer being delivered and are not appearing in my spam folder.

This started about three weeks ago with just one address. Now, I know of at least two.

Emails from these addresses that I used to receive and delete have also disappeared from my spam folder.

Does anyone have a solution?

I have a calendar that is shared by 4 devices. If I snooze or dismiss a reminder on 1 device, it should not affect the reminder on the other devices. Please implement a local snooze option at the individual calendar level.

I'm not sure exactly when this problem started but it could have been when I had to move my primary email from Xfinity over to Yahoo. Also not sure if this started after a recent Thunderbird update. I can not send new emails nor can I forward old emails. Haven't tried reply but suspect it is the same. This is the message I get: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again. All settings and passwords are correct as I can receive and send from all my different accounts using browser. I can send emails from my accounts, on my iphone, though not using Thunderbird on iphone. Account settings and passwords are the same on the phone.

I'm having a recurring problem with discrepancies in the message count when I move emails from one Thunderbird folder to another. I regularly "sort" my emails into specific folders based on topics and other search criteria, but I frequently encounter situations where the number of messages I see on screen in a folder is less than what Thunderbird lists as the total number of messages in the folder. Why is this happening and how can I view the missing / hidden messages?

I've been using T-bird since nearly the beginning, and I've always been able to search for a string in a message by hitting the slash ("/") and typing my search string. This appears to be a shortcut for Ctrl+F (on Windows, currently Windows 11).

With T-bird 151.0, when I press "/" it is ignored... the first time I use it. If I press Ctrl+F and do a search, then I can start all subsequent searches in that message with a slash. If I close that message and open another, I must again use Ctrl+F the first time I want to search.

My muscle memory constantly forces me to type "/<string>" to search, but since T-bird ignores the slash, the following characters immediately take action, usually causing me to navigate away from the message, mark them as read/unread or as junk, etc.

Since I can use "/" on subsequent searches, I'm thinking this is a bug, not a feature removal. Can this be checked/confirmed? ...thanks!

My Thunderbird has suddenly stopped showing date and size against incoming emails - it also wasn't showing sender but suddenly changed despite me not changing any options. Date and size are clearly ticked in the drop down box. Basically, it is randomly deciding what to display even when I am not changing options!

Most file attachments I receive open the correct program by file type. that does not happen for docx. Can I establish that default? If not, I have to save to tile system which will correctly handle the connection, but is not a desirable workflow.

I have recently installed Thunderbird. I have imported the .pst from outlook. I cannot see any email sent recently. Email display Window only shows mail messages from ten years ago. When I select get messages it states no new messages to download What do I need to do to fix this ?

Thank you Brad

Somewhere along the line, I lost all the entries in my Thunderbird address book. I tried to import from Outlook to repopulate it. This turned into a disaster.

When I get to the point where I can select the field, the destination they are mapped to make no sense whatsoever. For example, the Middle Name maps to the Last Name field. OK. Bad guess. But then all the drop down shows as options is Last Name. I cannot map it to middle name. The address book drop down only allows you to select what it is already set to.

Company Yomi (whatever that is) is mapped to Notes. At the end of the list, the source field Notes is shown and no destination mapping is available at all, so what happens if I select it.

I use thunderbird for a long time. all of a sudden, I can see the addresses of the mails that have arrived, but I cannot open them - I get the message "orange (imap.orange.fr) is unable to connect to thunderbird". I cannot send anything - message "close the program or wait for the program to respond" - I wait for a long time, a little circle keeps turning - that's all. the mail-orange functions without problems, but I prefer thunderbird. what can I do to re-establish the connection orange-thunderbird? thanks - sigrid

I get the message "Login to server mail.sasktel.net with username powalinsky failed" even though none of the sign-in credentials have changed and I can access the same account in a browser and on my iphone. This problem began last Friday. It has occurred occasionally and briefly in the past, seemingly resolving itself. I have tried the troubleshooting suggestions that I found online, but to no avail.

A page appears when I open Thunderbird asking for permission to allow Mozilla Thunderbird to access my google account. It asks for me to click on "allow" but nothing happens and the page keeps appearing.

I had Thunderbird on my Windows 10 computer. I bought a new Windows 11 computer and downloaded Thunderbird. When I try to set up my email account, I provide my full name (not my Thunderbird user name) and email address. The next screen has the message "Configuration found in Mozilla ISPDB ". I clicked on IMAP and hit continue. The next screen I type in my password for my Spectrum mail account. I have confirmed that the password works went I log onto the Spectrum website. The next screen has the Authentication error "Unable to log in at server. Probably wrong configuration, username or password.". I've also tried using my Thunderbird user name and Password instead of my full name and Spectrum password with the same results. I know my Thunderbird user name is correct but I can't be 100% sure that my Thunderbird password is correct.

I'm not sure if this matters but my email has the has the extension ----@socal.rr.com. This was assigned to me by my original email provider, which was Time Warner Cable. Spectrum bought Time Warner Cable a few years ago and I think Spectrum uses a different extension.

Thunderbird has been acting weird. For a week or so, it has sometimes been downloading only one message at a time when I hit "Get Messages." I have to keep clicking "Get Messages" over and over to download my email. Now, however, it won't retrieve any messages at all from that account. It goes through the motions, and says that there are no messages to retrieve, but there are. I have tried restarting, both Thunderbird and my computer, several times. I have tried compacting the inbox. I briefly got it working again after restarting, but it's back to not working and restarting does nothing. The online information tells me to delete my account and then add it again, but it also seems to indicate that if I do that I'll lose the email that is currently stored under that account. That's not an option! I am able to send messages, and Thunderbird retrieves messages from my other email account just fine.
