Hello Thunderbird Team,

I have 2 Gmail accounts currently linked to my Thunderbird program, and every time I start the app and every few minutes the app is still running, ever since the 15th, it's been notifying me of my account's set birthday on both accounts (main & alt).

And every time I close the event window, click "Dismiss all", or "Snooze all", it throws a 300 MODIFICATION_ERROR popup.

So far, I have not been able to fix the error through Thunderbird's settings, so if you have the solution to this, just let me know!

Best regards, opera

P.S.: I'm not sure if this is the right place to be sharing this on, or if I have to reach out to Google Calendar support instead. If you know where I should be taking this, also let me know!

Hello,

Since I updated to Thunderbird 137.0.1 (Thunderbird for NixOS, nixos - 1.0) I get the problem where every time I close and relaunch Thunderbird, only one account shows up. The first time, eleven of my twelve accounts disappeared, with only the one on top showing anymore (or existing in settings), and every time since then, if I've tried to add a new account, then it disappears.

Is there any info I could get that would help diagnosing this easier? Should I file a bug report?

Thanks!

After a power failure, upon reboot, Thunderbird wanted me to create a new account. I have three POP3 email accounts that I access through Thunderbird, and all are missing.

I have been selecting several different Help and Forum search returns to correct this issue, though none (that I can find) pertain directly to my specific problem.

I am running Windows 10 64 bit and recently downloaded T-Bird. (Last 6 months, auto updating) Per the Information section, T-bird is running the 32 bit version. (I don't know why)

I have located and read the article pertaining to T-bird self-creating a new profile. My old profile still exists, and I have set my old profile as the default to no avail.

While attempting to follow the instructions for copying my old profile to a separate drive and bringing it back, I noticed that both the "Imapmail" and "Mail" folders are missing from the root directory of the old profile. Doing a windows file search on the C drive, the only folders that appear on the drive are those of the new default profile created by T-bird after the power failure.

Looking inside the "Mail" folder in the new default profile, I see that it contains everything from my old profile. I copied the folder and placed it in the old profile root directory to no avail, though I have not done a re-boot of the computer itself.

One thing I have not tried is deleting the the new profile after selecting the profile as default. I am afraid to delete anything, as in my mind I may permanently delete something if I did.

How do I get T-bird to return to it's proper function where all my accounts appear upon opening of T-bird?

What is it looking at (points to) to retrieve each profile or the email accounts ?

Since the big wipe, I have lost all my identities, including my main. I had been using a second identity as my main for years. I can no longer open T-Bird because it tries to connect to the old wiped account. I want to start a new account, but do not have access anymore. I cannot receive an E-mail response to this question because my account has been closed, so do not know how to communicate with you.

Adding a Gmail mailbox in Thunderbird, I'm almost at the last step, but localhost refuses the request. What is the solution to this problem? (I can log into the Gmail mailbox on the web. I have also added other mailboxes in Thunderbird without any problem.)

I got an email that my mozilla data and account will be cancelled June 26 because I have not used it in 2 years. I use thunderbird for email. Isn't that a mozilla product? Was this email a scam? It asked me to sign in to prevent my account being cancelled. I decided to ask if this was really mozilla or a scam. Of is it that since I use thundI got an email that my mozilla data and account will be cancelled June 26 because I have not used it in 2 years. I use thunderbird for email. Isn't that a mozilla product? Was this email a scam? It asked me to sign in to prevent my account being cancelled. I decided to ask if this was really mozilla or a scam? Or because I use thunderbird instead of firefox that my account will be cancelled unless I switch to firefox?

Hello. I have been using Thunderbird on my desktop computer and K-9 Mail on my Android phone for several years. I have just updated K-9 Mail to version 9, which is now called "Thunderbird." One of my e-mail accounts is a POP account. Incoming e-mails on this account appear on both devices - desktop and Android - but e-mails that I send via my phone on this account don't appear on the desktop version of Thunderbird. Is there a way I can synchronize ALL the folders on the Android version of Thunderbird with the desktop version?

Thanks in advance for any help. Les

Problems with importing a profile having successfully exported it. As the profile is larger than 2GB I couldn't create a ZIP file. Having imported the profile my historical emails are not showing.

I tried to add a new email account (which is hosted by Gmail) to Thunderbird but Thunderbird, after finding the account in the ISP database, then tells me "unable to login at server. Probably wrong configuration, username or password." I have checked the username and password. There is no mistake. What do I do now?
