I use Thunderbird on my iMac (10.12.6) to access 6 gmail accounts to download them to my computer. Suddenly at about 1500 hours GMT it just stopped working. Please help. Kind regards Paul Partridge

I am about to move house so my address will be changing. Is it possible to create one e-mail with static data (new address) which also has a place for dynamic data i.e recipient e-mail address, different reference number etc?

I would like to have a base/master e-mail and then change it to write to bank, utilities, phone co etc with the relevant account no.

That way I can avoid having to type the same message many times with only minor data changes.

Thank you,

I am attempting to migrate my Win-10 Thunderbird v159.0 to a new Win-11 installation. The current profile folder size is too large for the automatic backup process (6.2 GB), so I am creating a copy of the profile folder structure. When I copy the profile folder structure into the copy buffer, no errors are shown. But, when I attempt to paste into a new folder, I am getting 13 messages regarding the filenames are too long for both sbd and mozmsgs filenames. Is there a maximum local folder name and/or local filenames limit. I can see where I can control the local folder name length, but not the local filename (email) name length.

There are 5 profile folders listed under the Profiles folder, their contents as follows: Profile Name Folder Count File Count Storage k1fx5scw.default 1,211 folders 24,946 files 3.78 GB (appears to be current default) 5zo1yxiu.default-release-1 17 folders 87 files 14.8 MB k1fx5scw.default.old 937 folders 21,555 files 2.29 GB (previous incarnation of default) rpsz3c78.default-release 14 folders 45 files 14.2 MB lhqhc5hj.default 0 folders 1 file 47 bytes

I use HTML as my signature. It has been working just find, but lately when people reply to me, their messages were coming in blue text. So today I changed the: Settings > General > Plain Text Messages > Quoted text formatting from blue colour to black (I have no idea how that was set to blue in the first place). that is all I did. Image attached of the change I made.

In any case, after that, when I tried to send a new email my HTML signature no longer displays the correct font (Pristina) but shows only variable text. The HTML file is not corrupt, it still looks fine in the actual file I saved, but, Thunderbird is changing it somehow. Even when I look back at sent files, Thunderbird is showing me the variable text and not Pristina.

Any assistance would be much appreciated. With thanks, NM

I've just added another new email account to Thunderbird, an AOL based account like the others. Thunderbird has created the account but has attached the 'inbox', 'drafts', 'sent', 'archives' from an existing account. is it possible to redirect where an account holds its group of folders?

I run an old imac with ventura 13.7.4, mostly i use my email prog from my server, but i can't get links etc. When i switch to Thunderbird, much of the time thunderbird just sits there, saying it's connecting, but it's not. i will dump it soon and try something else, i think. Sometimes it works.

I think i am running TB 159.0. I haven't the faintest idea how to access the TB app menu, but this is what it says on my app menu.

I can't upgrade my OS, it's a miracle this thing works at all any more. Yay for old geeks!

Can I use my start online login in that email in all areas online in that chat area is my email name as username? My original email login password if it is possible in chat or if I need in chat to do a DESKTOP area password ? and if my account number in GB can me used in the Local Alias of chat or if I need to copy that very long area you felt of starting in EB ?

Can I repair the chat in my email when you advised a Local Alias code for me of EB85BB5FA33A75E15E944E63F231550C4F47E38E in my chat restart after windows 11 damage when I have seen 2 areas of chat username in my email and chat password that looks a DESKTOP style with more rather than me online email login

I can't add my personal @hotmail.com account to Thunderbird. Every attempt ends with "Authentication error – Unable to log in at server. Probably wrong configuration, username or password." All my other accounts (Gmail and several Microsoft 365 business accounts using outlook.office365.com + OAuth2) work fine in the same profile.

Setup

• Thunderbird 160.0 (64-bit) on Windows (problem also happened on 159.0)
• Settings auto-detected by the Account Hub: IMAP outlook.office365.com:993 SSL/TLS OAuth2; SMTP smtp-mail.outlook.com:587 STARTTLS OAuth2
• POP3 (outlook.office365.com:995 SSL/TLS OAuth2) fails in exactly the same way

What happens

• The Microsoft sign-in opens in my default browser, I sign in with the correct account (2FA), and I get the "You're all set" page.
• With mailnews.oauth.loglevel = All, the Error Console shows a successful token response from login.microsoftonline.com with scopes IMAP.AccessAsUser.All, POP.AccessAsUser.All and SMTP.Send, and "Creating new login for ...@hotmail.com". Microsoft also emails me "New app(s) connected to your account".
• Immediately after that, account setup fails with "Unable to log in at server". The console shows nothing more specific.

What I already tried

• Removed and re-added the account several times; cleared the saved OAuth logins for this address
• Cookies are allowed; mailnews.oauth.useExternalBrowser is back to true (setting it to false made the redirect go to https://127.0.0.1 and fail)
• In Outlook.com: IMAP is enabled (toggled off/on and saved). The address is the primary alias of the Microsoft account. Two-step verification is on. Recent activity shows no blocked or unusual sign-ins, even right after a failed attempt.
• Webmail works normally.
• Microsoft support says nothing is blocked on their side and sent me here.

Is there anything else I can check, or a way to see the actual IMAP server response to find out why it rejects the token?

Meeting notices are showing locally as being stored in my Google calendar, but actually are not.

I have four email addresses in Thunderbird, say one@domain.com, two@domain.com, three@domain.com, four@domain.com. I get Microsoft meeting calendar invites from time to time at each of these addresses. I accept them.

I want my calendar also on my Android, so have subscribed to my Google calendar, say at address calendar@gmail.com, through the builtin Thunderbird feature of a calendar on the network.

After accepting a Microsoft meeting invite, say at two@domain.com, it shows up correctly in my Thunderbird calendar as being stored in my Google calendar:

  Calendar: calendar@gmail.com

But actually it is not in that calendar when I check the calendar on the web. And so of course are not synced to my Android.

Is the problem that in the calendar properties in Thunderbird that I have my main email address "one@domain.com" selected from the "Email:" dropdown? Should I change that to "calendar@gmail.com"?

If so, does that mean I also need to add "calendar@gmail.com" as an email account to Thunderbird? I have not done so yet, because I don't need email from that account, I am just using it for the calendar feature.

Thanks.

When I create an event in the Thunderbird calendar and enter text in the “Details” field, the text appears the same color as the black background, making it unreadable, as shown in the attached image. However, red and blue text displays normally. It seems there is no option to specify font colors in the calendar. I would appreciate it if you could suggest a solution. Thank you in advance.

Hi,

For both servers imap.exmail.qq.com / imap.263.net, when I click on the email subject in the email list during downloading processes (many emails headers are being downloaded but email body downloading is not completed), the email is broken without any content (only header).

I go to the web email server and move the email to another folder and then move it back to inbox. Then I delete the same email in Thunderbird and donwload again the email again, it's completely downloaded with the email body.

I don't have any issue with eM client or Outlook for such issues. Any possible setting to solve this issue?

Thanks.

I have saved my emails in the local folders, which is in my second drive (D Drive), I added extra folders named them as per year and in those folders per month. It shows the size of each folder amount of data but, nothing is there. I notice this when my C drive got corrupted and I had to reinstall windows 10 again. I did not reformat the D: Drive because there was nothing wrong with the drive. It used to be so easy in the pass to save emails. What is happening?

Thank you for any assistants in the future.

I've been having a bit of a nightmare - I was using Google mail - then I migrated to Proton - now I am going back to Google (for now).

I added my email address to Thunderbird and then had to installed Proton Mail Bridge to allow me to download all those emails to Thunderbird. This is apparently 9.5GB worth of email according to Mail Bridge.

Now when I open Thunderbird it keeps crashing, becoming unresponsive. I don't know how to proceed - do I need to sign out of Proton Mail Bridge - or Delete my account in Mail Bridge - or something else.

I can't tell if Thunderbird is busy "compacting folders" or some other task...

I have been in the meantime trying to delete messages from my Proton mail (in my browser) to see if that helps. But I can't tell if this is doing anything beneficial or not.

I literally can't open Thunderbird now without it crashing, despite me not taking any kind of action (just the spinning/loading wheel constantly visible).

Hope this is enough info but happy to share anything else! I have tried restarting the computer too.

Dear Thunderbird Development Team,

I am writing to share feedback and request an essential usability improvement regarding keyboard shortcuts in Thunderbird.

While drafting emails, I frequently trigger the Ctrl + Enter shortcut by accident. This causes unfinished emails to be sent out immediately, leading to awkward and unprofessional situations with recipients.

To resolve this issue, I attempted using add-ons such as tbkey-lite to remap or disable the shortcut, but the configuration proved ineffective. As a temporary workaround, I have enabled the "Send Later" / delayed sending feature so I can intercept accidental sends in the Outbox. However, this is only a band-aid solution and remains a constant source of anxiety while typing.

I kindly request that future versions of Thunderbird consider the following improvements:

   Built-in Shortcut Customization: An option in the settings menu to disable, rebind, or customize global/composer shortcuts (especially Ctrl + Enter).

   Confirmation Prompt Toggle: A built-in preference to prompt a confirmation dialog before sending (e.g., "Are you sure you want to send this message now?"), which would prevent accidental keystrokes from immediately dispatching drafts.

Thunderbird is a fantastic, privacy-respecting client that I rely on daily. Having better control over critical keyboard shortcuts would significantly improve the writing experience for many users who face the same frustration.

Thank you very much for your time, dedication, and continued hard work on this project.

Best regards,|

I've been using Thunderbird happily for many years, but a couple of days ago, it started making problems. It sometimes shows only my mail address, but no folders, so I cannot get to my mails. Sometimes it shows only the folder for incoming mails, but no "sent". Or "sent" ist empty. Sometimes everything works. (I have a second mailaddress in this thunderbird app, for which all folders are present, no problems there)
