Thunderbird Community Forum

I use Thunderbird on my desktop and since early June, I have not been able to receive any new messages but I can still send. Everything works fine on webmail (Yahoo) and phone (Samsung Galaxy), it's just my desktop which is affected . I asked Duck AI about this and this is what I got...

https://duckduckgo.com/?t=ffab&q=thunderbird+connection+to+server+pop.mail%2Cyaho.com++timed+out&atb=v417-1&ia=web

I tried the solutions offered without success.

Not sure if I picked the correct topic for this...

I had to reinstall Windows 11 on my PC as the old copy was corrupt to the point I could not install updates, even with Microsoft's help. Before I made the plunge, I used Tools -> Export to create a zip file on my D:. After installing Thuderbird on the rebuilt copy, I went to Tools -> Import to recover everything.

About 19% in, I received error "Import failed unexpectedly, more information may be available in the Error Console." I found the Error Console but don't know how top proceed.

I have an image copy of my old installation. Can I simply locate the Thunderbird profile on the backup and restore it?

Mozilla Thunderbird Snap for Ubuntuubuntu-snap-build - 1.0

Just want to open a 'compose a message' without the extra main window also opening.

Tried to ask AI - that was no help - no surprise.

All of my emails are being marked as read immediately. I have that option turned off in settings on all devices. I am not using bit defender. This only started after I moved to a windows 11 computer. I only have one account. I have read the previous forum similar issues.

Currently using 140.7.1esr (64-bit) and having problem with more than one contact having same email address. Looking at copy of sent email and address names are same, but floating over each the embedded are the correct names. Do recipients see same address?? Who is receiving the email -- very confused?? Would like to see correct names.

Appreciate the assist and have a great day.

Old PC died and will not start up. I bought a new PC and was able to recover most file in the initiating the new desktop. I installed Mozilla Thunderbird on the new PC, but when I opened it only 55 EMAILS were available with the oldest being about 2 weeks old dating back to July 16, 2026. Is there a time limit for maintaining EMAILS online? Also, all of my contacts and Calendar events are not available.

I had created several folders to save important EMAILS and none of those sub-folders are visible to me. How do I get to those folders and EMAILS? Contacts and calendar are not as important, but they were used all of the time to communicate and stay on schedule

I tried to import using the tool provided, but received the following message: Import failed unexpectedly, more information may be available in the error console.

I have lots of important information that I can't access!

Currently using TB 153.0, Win 11 on desktop PC.

In past versions there was a progress bar on right end of the status line, along bottom edge of the screen, that showed progress while TB was compacting folders. That bar hasn't been visible in last few updates.

When prompted today, I allowed TB to start compacting. I'd permanently deleted a really big bunch of old emails in last few days, so probably a lot of space that could be recovered. I kept waiting and waiting and waiting, but without the progress I had no idea if TB was busy or possibly frozen. So I just left it alone. When I came back and tried to manually start compacting, it immediately said "Done, 0K saved". So it had obviously done the compacting.

If it's an option, how do I enable that progress bar? If not currently available, please consider restoring it in future TB updates. I -for one- think it's a very useful feature.

THX!

I am unable to access my mails on Greenby with Thunderbird and I suspect the password is incorrect. I can read my mails on the Greenby server and know the necessary password but cannot work out how to enter this into Thunderbird! As I am no expert, a simple guide would be most appreciated! Thanks in advance. Roy

I was cleaning up my wife's email when I noticed there are a lot of messages unread and in the trash folder that ought not to be. I am wondering how to fix that for her. Example: some amazon.com emails about orders, or emails from favorite merchants or websites.

Right click not working on spam email

Lately I am getting spam with from addresses I can not use the right click on to copy the email from address for reporting purposes. I have to use the More option, View Source and then search for the From address and copy it from there. Can this be fixed?

I saved off the source if someone wants to see it.

I was attempting to import the calendar info from my old system to my new one, but the export/import of a .ics file did not work. It complained about information not being found. Then I tried copying the local.sqlite database file from my old system to the new one, that initially did not appear to work either :( Come to find out that the database cal_id fields did not match between my new system and the old one, so even though the local.sqlite file I copied had all of the calendar information, the prefs.js file on my new system was referring to a different cal_id. So I used a text editor to replace all of the cal_id's in the prefs.js file, with the cal_id found in the copied local.sqlite file, and now I have all of my calendar data available on my new system. You might want to make this know to your users, since my original searches on your support site did not present a solution that worked. :(

I am getting hundreds of emails a day from the following: Mailer-Daemon@gator3303.hostgator.com with this subject: Mail delivery failed: returning message to sender How do I stop this? Thanks

I need help. How do I troubleshoot TBird asking for a password that disappears when I go into troubleshooting mode? In other words, I can enter anything in for the password, or dismiss/close the pop up box, and nothing is effected by it. I still get all me email for all accounts. The only thing at the top of the box is a user name (pmruzicka). At this point, I have deleted the accounts that used that user name, including all info for the outgoing servers (even tho this password request pops up at TBird start). I have Disabled ALL extensions one at a time and the pop up still happens. I have set TBird to default them,e - pop up still there. I have unchecked the hardware acceleration box - pop up still there. I have no clue what else I could do at this point. I do NOT have a Primary password set. Can someone please help me figure this out? Getting tired of having to click off that pw box every time I start TBird. Thanks. Also, this has been happening through the last few updates of TBird.

I have been shifting my email platform from Comcast to the new Yahoo platform. This has worked for my iPhone and for my Thunderbird app on my iMac. But NOTHING works for this on my MacBook Air. My gmail is fine, but the only way I can get to my new Yahoo platform is to sign in via the web browser. Thunderbird will not configure for the MacBook Air, and I've tried 10-15 different things already (not an expert by any means). I have all the proper settings. I have reinstalled Thunderbird on the latter machine.

Does resetting your primary password in Thunderbird only delete the usernames and passwords in Thunderbird or does it also delete the usernames and passwords in Firefox?
