I moving from classic outlook to Thunderbird and I am having trouble finding how to change fonts and color in signatures for my emails. I do not do html it is a simple signature; name company name and phone numbers. I search and found no help. Is there a way to change color and font in the reply to an email? Sorry I know this sounds simple but I have been using outlook since it came out so this is similar but just enough to give me trouble. Thank you for any help, rick

I'm unable to send any email with Thunderbird on my new Windows11 laptop. I've used Thunderbird for years and years on the old Windows10 one, but it won't send anything with the new one. The version info it gives is "128.5.1esr (64-bit)" Whenever I try to send an email message, it waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username bill.marshall@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings. Authentication method looks fine, but the password (Settings->SavedPasswords) is empty (?? But I entered the password when I started Thunderbird and asked it to save it).

I have been receiving emails for my butlerfamilia@aol.com account on my pc, via Thunderbird, and on my ipad. Now both devices are saying the password is invalid. I have gone to the AOL website and changed the password and can receive emails at mail.aol.com. I have gone back to thunderbird and folllowed instructions to change the pw by deleting in settings and restarting Thunderbird and entering the new pw that AOL Mail recognises. But Thunderbird still says the pw is not valid. Any suggestions ?

Dear Support Team,

I am experiencing an issue where the "Send to -> Mail recipient" option is missing from the context menu in Windows, despite having Mozilla Thunderbird set as my default email client. Steps to reproduce the issue:

   I have set Thunderbird as my default email client in Windows 11.
   MAILTO links work correctly when triggered from a browser or PowerShell (e.g., start-process "mailto:test@example.com" opens Thunderbird as expected).
   However, the "Mail recipient" option is completely missing from the "Send to" context menu.

Additional troubleshooting:

   I have verified that MAILTO is associated with Thunderbird in the Windows default apps settings.
   The registry keys under HKEY_CLASSES_ROOT\mailto\shell\open\command are set to:
   "C:\Path\To\Thunderbird\thunderbird.exe" -osint -compose "%1"
   I have recreated the Mail recipient.MAPIMail shortcut in %APPDATA%\Microsoft\Windows\SendTo pointing to Thunderbird.
   I have reinstalled Thunderbird and checked MAPI compatibility, but the issue persists.
   Running rundll32.exe url.dll,MailToProtocolHandler test@example.com successfully opens Thunderbird.

Observations:

   The issue seems isolated to the context menu functionality.
   The "Mail recipient" shortcut does not appear in the context menu at all, even after manually creating the Mail recipient.MAPIMail file in the SendTo folder.

Could you please help me resolve this issue? Are there any additional settings or configurations I need to adjust to restore the "Send to -> Mail recipient" option for Thunderbird?

Thank you for your assistance.

Best regards, Ondrej

I updated from TB 115 to 116. I had to re-enter email and calendar (to Google) connection info. Calendar does not display. Email and Contacts seem alright. Is Provider still needed?

For the past twelve days, I have been having inconsistency with my e-mail.

I am sparingly receiving e-mail and, I can't send any e-mail. My ISP said, given the error code I was getting, when I tried to send, that. The problem was with Thunderbird.

Hi Team I just changed to a new PC and followed the instructions on how to migrate over my Thunderbird account and whilst everything when well the spell check no loner works. On the previous computer it would show misspellings in red as I typed and then when I pressed send I would get a further check...this no longer happens I no longer get spell check as I type or when I hit send yet I get a blank box (see image attached)

Also I did try to set up a chat account 3 times but each time it did not allow the nickname (see image). Going forward this could be a useful option when encountering new issues.

can you please help me out on both issues as it is really becoming frustrating and I really do not want to go back to Outlook? Regards John Prendergast

Hi I have problems after my Thunderbird latest update to 128.5 esr(64bitd). The picture file of my signatures has changed to a larger size, and none of the instructions issued to change this are working or are not there.

I attempt to setup an outh2 mail account for hotmail.com 1) Go settings (gear symbol lower left) Account settings, Account Actions, Add mail acount 2) Typa new and Email Address and click Configure manually 3) Select OAuth2 by both Authentification method Incoming and Outgoing server 4) click Re-test (test is incomplete so) 5) For outgoing server type smtp.outlook.com, 465 and SSL/TLS 6) The done button is grayed out, It is not possible to setup the account

I thing Thunderbird is the nicest email to use but

I have an old "live" account, a "G mail" account and a newer "Outlook" account. They all receive emails fine. The G mail account will send emails. The other two will not. Can I get the setting for smtp for both live and outlook please. I have searched for some time and find different suggestions. Thank you, Garry

Previous versions of T-bird I could click on sender at top of message array and that array would be alphabetically sorted. Click on Date and sort would be by sent date. Now I can no longer do that. How can I accomplish this simple task in latest T-bird version?

When I turned on my computer today none of my emails are coming in or going out I have not changed anything I went thru the trouble shooting and nothing changed Not sure where to even start

Hello,

I did change the signature of one of my accounts in Thunderbird and it does save the new information. When I restart Thunderbird it keeps the old information. I tried a signature in HTML, or with a file, it is the same problem.

Thanks for your help.

When I attempt to add a Gmail account, I get this error - "Unable to login at server. Probably wrong configuration, username, or password"

Below are the steps with screenshots: - checked for no cookies to prevent Google from asking for an actual login - no stored google passwords - didn't put in my password on setup - TB finds the available configuration - prompted to login at google - add google password - allow access - error message

I have restarted Thunderbird. I have checked for updates (even though I have it on auto-update).

Are there settings on my Google or Gmail account that could prevent this from working?

Messages no longer have any details. There are subjects and a link to browser only. I do not know why this has happened. I'm not aware of making a change like this.
