Outlook.com and Microsoft inform me that in September 2024, Outlook 2007 will no longer work for email because it does not meet their spiffy new authentication thingy. They want me to quit using Windows 7, but I need it to run legacy productivity software for which there is nothing comparable. So, Windows 7 it is. I do have a dual boot system that includes Windows 10, but I don't want to mess with it for email if possible.

Microsoft suggested that Thunderbird would work, so I downloaded it. That's when everything went sideways. There is no utility to move my existing files and folders intact from Outlook 2007 to Thunderbird. I tried Thunderbird's Import but it refuses to cooperate. So, last chance for Thunderbird is contacting you.

Help me make a clean transition from Outlook 2007 to Thunderbird without losing contacts, folders and files.

Hello, our company changed login to our outlook accounts to always use two factor auth. Since that change I cannot login nor create new account in Thunderbird, because the window where I should login to my account is just blank, see attached image.

I have downloaded Thunderbird to a new Windows computer but cannot connect to my Spectrum server. I have 2 other computers with Thunderbird which work fine. Spectrum is unable to help and feel there may be an issue with Thunderbird. I have uninstalled and then reinstalled Thunderbird to no avail. Any clues, anyone?

I've just replaced Windows 10 with a clean install of Windows 11 and then did a clean install of Thunderbird. No snags and Thunderbird is working fine on all my email accounts. BUT No Thunderbird folders in Windows Explorer are visible. I've looked for my Profiles folder where Thunderbird says it is but it's not there or it's invisible! Similarly there are no visible Thunderbird folders under any program folders. As my emails are working fine, none of this would matter except I do local email backups using a batch program run by Windows task scheduler so I need to be able to get to the profiles folder for this (been running fine for years under Windows 10). Also I'm curious! So, is this entirely a Thunderbird problem, or entirely a Windows 11 problem, or some interaction between the two. Any solutions? Many thanks for any help you can give. Clive

When I install Thunderbird, either the Microsoft-approved version (129mb) or directly from thunderbird site (119mb), I get the attached error message. It doesn't matter if I click Cancel or click "Confirm Security Exception", I get the same result. The initial result is that I go into my new Thunderbird email account and all appears fine). But when I try to send an email, I get that same message again (altho with a different 3-digit number following imap.gmail.com) followed by a "message couldn't be sent" error message.

Hello,

I have several email accounts stored on a different internal hard drive, when I say stored I mean choosing a different location in the thunderbird account settings for each email to store the mail boxes, filter rules etc.

I sent my machine back in for repairs and long story short the OS drive ended up being wiped. From what I've seen, in order to import the email profiles which seem to be stored on the OS under approaming or something similar.

I'm struggling to find a way to import my existing accounts with what I have on my other drive. Any ideas on how I might be able to do this?

I'm trying to import emails that I backed up from my wordpress website's hosted email on hostgator. I have downloaded a mail.zip file however when I try to import it using Thunderbird it shows 0 emails imported. How can I import the emails using the file I have?

Thanks in advance!

The mother board on my old computer crashed and I needed to get a new computer. Old computer will not post or boot-up. Is there anyway to retrieve and transfer my Thunderbird email files to my new computer when the old computer will not post? Thanks!

I recently converted from POP to IMAP. It appears old messages from POP were automatically migrated to the IMAP Local Folder, but how can I confirm that before I remove the old POP account? The conversion instructions said I needed to manually move the old messages, but they are already in the Local Folder.

I have been using thunderbird for a few years My email was so big had to put it on a seperate internal drive(A:) My c: drive crashed reinstalled windows but cant seem t figure out where my old emails are. I am sure they are on the A: drive somewhere just cant find them Searched for "Profile", "Thunderboard" Large files just doesn't wnat to show up I guess I am IMAP so it will repopulate just bothers me that I can't find it

The message pane in thunderbird is dead after upgrade from 102.12.0 to 115.8.1. New messages won't show up automatically. I allways have to try to scroll down the message list to see if new messages have arrived.

I run Thunderbird on OpenSUSE Linux 15.4.

At Christmas last year I made a complete back-up which came to 6.1Gb. This March my computer crashed and I had to re-install the operating system and all of its programs including Thunderbird. But the backup zip file (when extracted to a folder from the zip file) is in sqllite files, not profile or ics calendar formats. Thus the backup cannot be restored. How do I get Thunderbird to accept these types of files to import the address book, calendar and message filter?
