Thunderbird Community Forum

Dear technician,

I have configured my email account to Thunderbird mailbox, but the email sending speed is too slow and cannot be sent successfully.

When using Thunderbird mailbox mail merge plug-in, it always shows: Your email has been sent, but due to network or file access errors, the copy could not be placed in the outgoing backup folder (sent). How to set up the account to solve this problem, you can put the email into the outbox or draft box of the email account.

How to activate Thunderbird mailbox account enterprise version and enterprise version fee and daily email limit?

Since the last update of Thunderbird, my mouse is showing a zoom-in icon when attemping to go to an interent link in a mail, rather than the normal "hand" icon for accessing a link. I basically cannot get to the majority of links in my incoming mail now.

In the attached screen pic, see the mouse zoon icon midway above the I and G.

Hi Community,

I having the issue, more or less permanently, that Thunderbirds crashes all the time during my normal working hours. Never mind if running in troubleshoot mode or default. I already created:

a) Created the IMAP Files new b) Cache relocation to RAM c) Profile is running on an NVME d) deactivated add-on e) many other things I tried.....

It happens out of a sudden, it just crashes - for 10 - 30 seconds and continues to work. Sometimes 4-5x per hour and then only once on one day. I have no idea anymore. Can I not create a crash report and share it here somehow?

On weird thing. I copied the profile to my second Personalcomputer, a windows 11 machine and with the same profile and settings - Thunderbird does not crash, it was running for days with my Thunderbird Linux profile. Working with Windows is no solution - it was just for the purpose of testing.

Thanks! Wolfgang

I have set up GPG on my own computer. My friends computer is on the same system, F41, Sway, Thunderbird. All updated.

My GPG in Thunderbird works, and the other system hangs for around 30 seconds then return “failed to send mail”. The error console returns the following:

We followed the instructions Encrypt emails with Thunderbird and GPG | Bacardi55's Web Cave and GPG Keys Management :: Fedora Docs which as I said results in my other system working as intended.

Could the non-working system be missing a package or a pointer set incorrectly? GPG and GPGME are installed. Keys are configured.

Somehow I have lost my primary password and I have used the error console solution - openDialog("chrome://pippki/content/resetpassword.xhtml") and I have clicked on the reset password button and get the message 'your password has been reset' What do I do next? I don't know how to proceed from there. I still cannot access my Thunderbird emails.

Background - my old (selfhosted IMAP) server died, I was able to recover the Maildir but for whatever reasons both dovecot and courier ignore the "message read" metadata embedded in the filenames so the local copy in Thunderbird is suddenly the most authoritative.

But every time I try to bulk copy from the old account to local folders or to my new server it fails because it tries to contact the dead server.

Looking for ways to attack this problem

I have bought a new computer. I had 3 acounts in my earlier computer. I could inställ 2 of them in the newncomputer. But for the 3rd i get a errormessage that is was the wrong password. How can I change to a new password for this account? Regards Sven Palmgren

I accidentally updated thunderbird and now all my individual folders have disappeared as well as my address books. It also redownloaded 886 messages dating back to 2022!! Help. I really need my sorted folders back and all my addresses.

For the 3rd time in the past 10 months, I cannot receive or send emails through Thunderbird on my laptop. Again, a pop-up states IP address is temporarily blacklisted and another states cannot login to imap.comcast. This always happens after a Thunderbird automatic update. (Last auto-update was Jan. 22, 2025. Haven't been able to access Thunderbird email since then. Have checked settings and all are set as required. Have reset modem and router. Have deleted all junk emails. Know it's not a Comcast issue as I am getting my Comcast emails on my cell phone via my BlueMail email app. (But cannot work on emailed documents on my cell phone.) The other 2 times this happened, email began loading after 10 days of no activity. No rhyme or reason. Have checked the box for a status update but reports come through via email... which is currently not accessible via Thunderbird. Why does this continue to happen? Please help!

Hello

Overnight Thunderbird has developed a major problem. The count for the number of mails in a folder is correct, as best I can tell, but when I open the folder it is either empty or has fewer mails than the count. Based on several tests, repairing sometimes adds more mails, sometimes not, but never the entire folder.

I repaired the inbox and it is now showing several mails that I deleted in the last few days (by emptying the delete folder having previously deleted them). Curiously, they’re all the same type, routine mailings about road works.

I may have backup in that I copy the entire Thunderbird folder to an external drive every morning, including today, and to Google Drive every Wednesday.

Please can you help.

Thank you

I have several POP accounts from one email service each with its own profile, and several other (IMAP) accounts from another service that share a profile, which includes access to local folders that store saved email from all three accounts. I like the shared profile as I can see all accounts there by opening Thunderbird once, but I have no interest in seeing the email from multiple accounts in the same inbox for organizational reasons. Apparently I created the shared profile when I first opened those accounts. I am interested in combining the now separate POP accounts/profiles so that they all open at once in TB, but not in the same profile as those currently sharing a profile again for organizational reasons. End results two profiles one for service one and one for service two each of which opens showing all the accounts from that service and having local folders that are shared. Is it possible to do that? I expect there may be a problem with combining local folders which are currently in three separate profiles so the stored emails are accessible in the combined profile. In that event, I would plan to keep the separate profiles only to access those stored emails and disconnect them from getting new email using them only to access the local folder stores they already contain, and use the new combined profile to get new emails and store only new email copies locally.

so i made my Microsoft account mario64@GMAIL.com insted of mario64@outlook.com so then how can i use my microsoft account WHEN thunderbird knows @gmail= gmail.com and knows @outlook = outlook.com PLS HELP PS: im useing family link so im useing a bypass from microsoft. ;)

Just setup a second Thunderbird profile for Exchange. Using Owl for Exchange plugin.

I right click onto a subfolder, and pick Properties, then go into Synchronization. I click onto a checkbox for "Select this folder for offline use" and I hit OK to close the window. Nothing happens. I go back, and the checkbox is not checked. I tried hitting the Download Now buttons, nothing happened.

Any clue why my check box selection is not accepted?

When I used Outlook, I set it up to use OST, so I have a copy of my email that is on the remote Exchange server. Now I am trying to do the same with Thunderbird.

Thank you

One of my TB accounts has two archive folders, one named Archive and one named Archives. The Archive folder has nothing in it while the Archives folder has several years of messages in it. How can I delete the non-functional Archive folder?

Thunderbird help,

    I have two computers which have been running Thunderbird for years, but the program on one of my computers has become corrupted and won't work at all. When I try to to reload an older version (2022 yr) it won't work, claiming  I have a version running. I need to know how to install the latest version.
   Thanks for any help you can provide.  - Dave

Hi,

 I am having a random problem with Thunderbird asking me for the login credentials to the email account when these should be stored. Possibly this problem is caused by the antivirus, outages or saturation of the internet connection or the mail provider itself giving a login failure and consequently, requesting the login credentials.

 The only check I can do is to check in Settings -> Privacy & Security -> Password and I see that only the outgoing mail credentials are there but not the incoming mail credentials when they should be stored.

Would there be any possibility or option to never ask for the credentials and can only be changed from the password window?

Thank you. Regards

I have just installed the latest version of Thunderbird in my new Windows 11 desktop. I have set up two email accounts with all the correct Charter Communications server information. It seems that when I enter the account user name for one account SMTP setting it migrates to replace the user name for the other account as well. Thus only one account can send emails! As an aside, when asked to enter passwords for each account I do not save them to the password saver. Any thoughts as to how to keep each account's user name intact in the SMTP settings would be appreciated. Thanks in advance.
