Thunderbird Community Forum

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.

The Reply command no longer shows when I want to send an email back to the person that sent it. There is a note at the bottom of the email that says: A unique identity matching the From address was not found. The message will be sent using the current From field and setting from identity Vince Hunter < [email protected]> Can you give me instructions in laymans terms to fix this bug and return it back to the way it was?

I have Version 128.5.2esr (64-bit), it says it is up to date.

So I've been noticing a couple of days now that I can no longer view messages in the message pane to the right of the screen. When I click on an email in the list on the left, the top of the pane on the right shows me the To, From, subject etc, as well as a yellow bar saying "Warning: To protect your privacy, Thunderbird has blocked remote content in this message." Then, nothing underneath this. Where it used to show the email contents. I do NOT want to have to double click every single email in my inbox to look at them in a separate tab. Most of what I get is not useful. I want to be able to click once and preview the email, then click Down to check the next one, and on and on the same as Thunderbird did it LAST WEEK.

Can someone help me get it back to working please? Thanks!

Morning people again..

I asked yesterday and got a reply, THANK YOU, but I cannot reply to that person as Outlook is really being silly.

I tried, and only succeeded in deleting that email.

I believe I have an "old" Thunderbird program on this laptop, and even though I have downloaded the New version, it is picking up that old version, from about 2023.

OK, my IT nerd neighbour is coming over later, and she will wave her "magic wand" and see what is going on.

I know the IMAP, POP etc codes for Outlook, and manually changed them last night, still the login via T Bird fails.

I can read replies, and suggestions, but I CANNOT reply to you. Frustrating, heck yes, and almost rude on my part, but NOT my doing.

Thanks for understanding.

Thunderbird 115.18.0 (64-bit) Win 7 (technical competency level - meh...)

I'm running Thunderbird because Windows mail Live 2011 finally got shut down. I've set it up with multiple gmail, hotmail and my websites email accounts, but the Hotmail passwords/logins keep getting altered between accounts and I get login errors (see pic). I'll go back straighten it out and the various accounts will pick up another accounts smtp info and populate it to all the hotmail accounts. Only seems to happen to the Hotmail accounts. It will then automatically ping hotmail with the incorrect info so many times that I'll get locked out and have to regenerate a new pw. The mix up is sort of like- Hotmail 1 - Hotmail 2 smtp Hotmail 2 - Hotmail 2 smtp Hotmail 3 - Hotmail 2 smtp Hotmail 4 - Hotmail 2 smtp Gmail 1 - Gmail 1 smtp (ok) [email protected] - [email protected] smtp (ok)

Does anyone know how do I can get my feeds back? I hope all my saved feeds are still stored somewhere as I use them for research. I just went to look something up and the whole heading is totally gone!

I tried gleaning this single outgoing email of "excessive spam/sales language" (I am only thanking someone for their purchase, not asking for another); "excessive links" (they and their graphics were fine before). no "excessive emailings/quantities" (I am only sending one single email and don't do more than a few with this content ever and haven't send even one email like it in weeks); co0ntacted my internet provider (RCN Astound can't help me and told me to contact Thunderbird), I already checked POP & SMTP stuff...

"Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-101] Message blocked due to spam content in the message.. Please check the message and try again."

What do I do?

I even checked that I had the latest version of Mozilla Thunderbird: yep! :/

In Thunderbird for Android, when I set up first account, I was asked if I wanted headers only, or full email, and I picked full email. When I set up a second account, I was not given that option, it defaulted to full, and I have not found a way to change that. Can I set that per account, or are all forced to be the same as initial selection?

I want to keep using the original mail app on my phone for primary email account activity, and use Thunderbird on my tablet for multiple lesser-used accounts. But when using tablet would like to be able to monitor the primary account, and possibly use its address as the sender when forwarding an email from a different account (I do this on desktop version now). Is this possible? Or too much mixing and matching? Thanks

I have used Thunderbird for decades with no problem. On a new Windows 11 machine, though, I am having a problem. I am running 128.4.2esr (64-bit) and just reinstalled it, but keeping the profile folder.

When I start Thunderbird, it should open to mail, specifically a unified inbox and various other mailboxes below. Instead, usually, it is blank. Other reopened tabs correctly display their title and content. See screenshot.

Thunderbird works correctly if I start it in troubleshooting mode, but at this point my few add-ons are disabled. (Quicktext, Compact Headers, dark theme.) See screenshot, lightly redacted.

With Thunderbird running, in its bad mode, selecting "mail" brings up the same blank page. Also, "calendar" shows a correct list of my calendars but will not display their content. However, "address book" works, showing my address book correctly.

If I am lucky or patient -- waiting for the mail tab to potentially come to life -- Thunderbird occasionally works and, if it does, stays fine for days, as long as I don't close it. What could be going on and what should I try doing?

Thanks for any and all help.

Just upgraded to a new system with Windows 11. Avast Security. Installed Thunderbird 128.5.2esr same as on old system. Migrated old emails using MozBackup. Worked great for a day. New emails, archived a bunch of emails to a local folder...

Next day after about 3-5 minutes Thunderbird shows the Hourglass and is not responding. Eventually will go to a greyed out window. I have to kill it with task manager. I noticed that in Activity Manager three calendars were syncing for a long time. Disabled all calendars.

Task manager shows CPU usage but 0 Network and 0 Disk activity. 3 sub processes but only one has CPU. Resource Manager shows CPU and 72 threads. Resource Manager - Analyze Wait Chain - reports "waiting to finish network I/O."

I've tried Troubleshooting Mode. Still froze during Troubleshooting Mode. I've tried moving a large local folder out of the mail folder entirely. I've tried clearing the startup cache. I've tried clearing the system temp folder.

I have a lot of accounts, saved emails and message filters. So I really don't want to start over again with an empty Thunderbird and reset up accounts.

Thunderbird fails importing a valid VCARD file with the error console displaying the error in the attached image.

I suspect that whitespace is not being stripped before checking for "BEGIN:VCARD"

I am happy to provide the VCARD file but there doesn't appear to be any way to attach files other than images.
