I have my own mail server and use different addresses for different services. When I reply to an email it always changes to my default address (myname@mydomain.com). When I receive an email to servicename@mydomain.com I want to reply with the from address being servicename@mydomain.com, not myname@mydomain.com. I can edit the address manually, but sometimes I forget and I end up sending replies with myname@mydomain.com. servicename can be variable per email.

Current faulty situation:

   Receive email incoming to servicename@mydomain.com

   Reply from address should be myname@mydomain.com

New wanted situation:

   Receive email incoming to servicename@mydomain.com

   Reply from address should be servicename@mydomain.com

This was built into Thunderbird for a while now.

   Go to Account Settings

   Enable Reply from this identity when delivery headers match

   Enter your domain prefixed by a wildcard (*), for example *@yourdomain.com

   Close/confirm all your changes

   Open an email that was sent to one of your catch-all addresses and click the reply button.

   The FROM field should be the catch-all address and not your general address.

But it has been broken for a while now.

My mail provider requires the usage of portnummer 143 together with encryption method SSL/TLS. Thunderbird automatically uses encryption method STARTTLS when port # 143 is entered. This is according to the recomended usage of special port numbers, but I need no correction from thunderbird, when my stupid provider wants to use ist differently.

It might be a very strange question/request, but I would be extremely helpful to if someone from Thunderbird team export and send the manifest of the App Integration that Thinderbird is using to be able to allow users to use the IMAP API of Microsoft Exchange. The one that defines some permissions, like Microsoft Graph's `IMAP.AccessAsUser.All`.

I've been struggling to setup a working app registration from our internal integration needs, and IMAP authentication is failing, while Thunderbird Enterprise Apps works great. As I couldn't get adequate support for troubleshooting this by Microsoft, my only hope is to try to compare something that's working with the app registration that's not working and analyze what's different.

So if someone from the dev/devops is willing to share the app registration manifest (of course, with any confidential data stripped off), I would be extremely thankful.

P.S. I think the manifest should be accessible at https://portal.azure.com/#view/Microsoft_AAD_RegisteredApps/ApplicationMenuBlade/~/Manifest/appId/9e5f94bc-e8a4-4e73-b8be-63364c29d753/isMSAApp~/false (though I'm not sure that the proper App Registration ID).

Can't seem to get thunderbird to connect to my xfinity (comcast.net) email... tried full reinstalls, changing the password, and all the steps in this: https://support.mozilla.org/en-US/questions/1437228

As well as trying "normal password" instead of OAuth2. The OAuth2 option does not seem to generate a pop-up to authorize that way. Using other 3rd party and logging in via browser also work.

Does thunderbird need to update something to fix the issue? Its been only a few weeks now for me that this was an issue.

Hi, I have two Thunderbird accounts and have just added a third. I can't receive any new emails on the third account, nor can I drag and drop emails from one account into the new one. I'm using Windows 10. I have not had any problems before this. I have tried deleting the new account and then reinstalling it, with the same problem.

I am preparing for a transit from MS and Outlook to Linux and Thunderbird. My outlook is set up in a way that all pop-3 accounts are in one PST file. I have almost no experience with Thunderbird, though I have set up Thunderbird on a test laptop and created one account as IMAP to test. this works nicely. I want to cancel my MS office subscription to not being forced into windows 11 in 2025! Office libre does the rest of the office app job.

BUT Outlook seems a different beast. Now, for the transition form Outlook to Thunderbird I will need to move over all PST files (the current one and all archives):

How can I import a PST file (which contains data of several e-mail accounts) into Thunderbird.

Does that work at all? If so, (I hope) how do I need to set up Thunderbird with all the accounts which are in the PST? What are the pitfalls? Should I use an automated (software solution) to be on the safe side or just not to not screw up?

Thanks a million for your tips and help

I have multiple Gmail email accounts and just purchased a Windows 11 computer. Upon installing and opening Thunderbird and adding my accounts, I discovered the first Gmail account inbox does not retain READ emails like it always had before. After reading them, they disappear and are only viewable in the All Mail folder. It seems I can only view UNREAD emails in my first account's inbox. However, the second and third Gmail accounts DO retain READ emails in their inboxes.

In my Google calendar, I have the automatic birthday calendar. The birthdays of people in my (Google) contact list will appear in my calendar. See the first attached image.

In Thunderbird, I have subscribed to my Google calendar (and Google contacts), but birthdays are duplicated in my Thunderbird (Google) calendar. See the second attached image. One birthday appears to be originating from the Google birthday (red) calendar, and one from my main/personal Google (green) calendar (which has two icons that I don't know the meaning of).

Why are birthdays being duplicated in Thunderbird?

In Thunderbird, I can resolve the issue by unchecking the option to 'Sync from <email address>' in the settings for the birthday calendar in my Google account. See the third attached image. This solves the problem for Thunderbird; see the fourth attached image. But then in my Google calendar, birthdays disappear. See the fifth attached image.

Is there a solution that allows the birthdays calendar to be synced correctly in both Google and Thunderbird without showing duplicates and without disappearing?
