All Office365 folders have disappeared
My company email is Office365 and I've been using it through Thunderbird for years with no (serious) problems.
I haven't changed any settings or anything, but yesterday I opened Thunderbird on my work computer, and all the folders disappeared except Inbox and Deleted Items.
To see if it was just that computer, I tried on a home computer and the same thing happened. Both of those are running TB 52.9.1 (to use the AttachmentExtractor addon). That machine also has Gmail IMAP which has no such problems.
My main home computer is running TB 78.10.2, so I thought maybe it was a version thing, and I backed up all my ImapMail folder and then ran that, and again all folders except Inbox and Deleted Items disappeared.
The only thing in the error console is 6 instances of NS_ERROR_FILE_UNRECOGNIZED_PATH … nsIXPCComponents_Utils.readUTF8URI
If I click Subscribe... it shows all the folders as unsubscribed, but if I click Subscribe on them, nothing happens.
All the folders still exist on https://outlook.office.com/

If I Subscribe to a folder, and then restart, the folder appears for a second and then disappears. There are no errors in the error console with timestamps at the moment that it disappears.
I had no problems until today. My problem may be slightly more complex. I set up Thunderbird and it was working fine. Unfortunately my e-mail provider is GoDaddy, which now provides Outlook for mail. They just switched me over and there have been multiple problems. I called about a problem yesterday. In the process of "fixing" it, they reset my password. They said I could just switch it back. That was not true. They changed the password policy to require 9 characters, in the past it was 8.
I logged into Thunderbird and it complained the password was wrong. So I entered the new password. Again, it said it was wrong. At this point I was seeing all my folders. I tried again. This time, it let me in, but all my folders vanished when ThunderBird updated the INBOX. I see new mail in InBox, but no folders. On top of that, the folders in AppData have been deleted, i.e. I had ATT and ATT.msf, the former is gone.
As discussed by endolith, I tried to subscribe to the missing folders. I see the list of all the folders, but subscribe then OK- nothing happens.
I tried some debugging and things got worse- unsubscribe from all the folders. All the msf files go away. Resubscribe to ATT- ATT.msf comes back, but nothing downloads. Resubscribe to the rest- nothing, the lost msf files do not come back.
I have Thunderbird ask me each time whether to make it my default e-mail reader.
Also as discussed, Thunderbird initially shows the folders when I restart it and the prompt to Set as Default comes up- then they go away when I say skip.
I created a new profile for the same IMAP account. That way I could give it the new password from scratch. I subscribed to all my folders. The msf files show up. If I go to AppData I see them. But nothing downloads. When you go to Options-> synchronization->Advanced, none of these folders show up.
Getting force to move to Outlook was bad enough, but these Thunderbird problems are pushing me over the edge!
I did save a copy of the profile. But just copying in the mail files does nothing. For some reason they are called ATT-1 and ATT-1.msf, in addition to the ATT.msf. I see that in another e-mail account I set up. At this point I am afraid to even open that one in Thunderbird- it had GBs of mail in folders.
One more note-
I copied the profile over that I had saved. It comes up, though the password is wrong. All the folders are there displayed in the interface and the folders are in AppData. As soon as I enter the password- no folders are shown and all the files are deleted from AppData.
