I just installed Thunderbird 91.8.1 and would like to migrate pst files generated by Outlook 2010.

It somewhat works - if I do "Tools --> Import --> Mail --> Next" and select Outlook, Thunderbird starts importing apparently all the pst files that are present on the PC, without allowing which ones to import to be explicitly specified.

Is there a way to specify which specific pst files are to be imported?

Good Evening, I had to reinstall Windows 10. My computer repairman installed Thunderbird along with much of my software. Since the reinstall I cannot Upgrade to Thunderbird 91.8.1. The auto update fails and the re-install does not upgrade to the new version. I have downloaded the new version many times and it still stays with the old version after the re-install. A couple times Thunderbird said I had the new version after I re-installed Thunderbird, but after restarting Thunderbird it goes back to the old (91.7.0) version.

Should I delete Thunderbird before I try to install? If I do will I loose all of my E-mail and folder information?

I would appreciate any advice. Thank you, Terry Prather [removed email from public]

I recently upgraded my Phone and now using Android 12. I logged into my Mozilla account using my email address successfully so it seems but now my saved collections have disappeared..What's interesting is that now when I look and my profile ID it shows a different user name. What can I do to recover my account etc ? Not sure what the issue is here.

Today, I am very dissapointed to report, I will be leaving Thunderbird after 20 years... Because it does not work with Microsoft Exchange Server. I am soooo dissapointed!

Hello, I've just set up Thunderbird on my IMac OS Monterey version 12.2.1 and have synchronized my gmail account. However not all folders have migrated. What is causing this and how can I fix it? Thanks!

i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

I upgraded from Thunderbird 52 to version 91. Even though all the account settings appear to be correct, I can neither send nor receive mail. What the -- is wrong?

My windows 10 took a powder and had to have it repaired The thing that i may not be able to get are the add ons and the address book that i had on it they are installing anew hard drive but were able to back up some of the files and such. I know it is something about address book and history but not sure how to do it .i and when it comes back can i come back and get help

The situation is bad for my hard drive, not enough room to import the outlook files into TB. So is there a way of moving the destination for the import function to another drive so I can collect my eamils to use in TB?

OR

Can I somehow split the import of the emails into 2 or three attempts then save to a memory stick step by step?

I am really stuck so any help I would appreciate please!

I experienced a problem with Thunderbird suddenly not recognizing my password. Kept giving me a notice that said my password/account had been "blacklisted". I've never seen that in 20 years. I called my local internet company, Comcast.net for help. He walked me through deleting and re-installing several times before it dawned on me that Bitdefender (anti-virus software) might somehow be blocking my password. I turned off VPN and unchecked all the boxes at Bitdefender. And I could suddenly reinstall Thunderbird e-mail addresses. HOWEVER, all the folders, which I think were stored locally (on my laptop) are gone. I had lots of stuff I use on a daily basis in those folders. How do I get them back? Can I get the back? My server is IMAP but I don't know if they were stored online or on my laptop. Somebody help me, please?

'trying to sign on to zoom successfully, then once in I get a notification saying I need to download the lastest version, Ive tried 6 times bianary file and then nothing happens '

firefox updated itself, which normally would be fine, but now there is a PDF icon in place of my normal firefox icon, and I am afraid to use it now. Is it for real?, can I change the icon back to the old firefox one? Please let me know cause I won't use it now until I know for sure that it's ok and get it back as it was. thank you, Linda

So Firefox did an auto-update a few days ago, and when I opened the browser EVERYTHING was gone. Passwords, bookmarks, etc.

I've managed to get the old bookmarks moved over, but I cannot for the life of me figure out how to get the old passwords back. The old data is in a folder on my desktop, do I just copy and paste the login and key 4 files from that folder to the new folder?

Sorry if this seems like a dumb question, I'm a pleb and this is the first time I've experienced this. :(
