Windows 10: Windows is blocking Thunderbird from getting mail and saving passwords

When both Windows and Thunderbird are in normal mode retrieving mail and saving passwords does not workhere is the problemWhen Thunderbird starts it asks for the password to get mail. After entering the password, Thunderbird hangs with 'Host contacted, sending login information'A pop up window then comes up with 'Sending of password did not succeed'The email profile is saved on an internal network server with this path \\Legend\Email\JAB\MailThunderbird works correctly when Windows is in safe mode and/or Thunderbird is in troubleshoot mode. I have tried disabling the Window Firewall and Viru

Thunderbird Mail Disappearing

Ok so this may or may not be the right area for this, but I wasn't really about to find a place for it and it is kind of network related.

So I have a client of mine that worked for a real estate company, and was about to leave the company, and wanted to keep his emails. So I downloaded Thunderbird, and saved all the emails for offline mode, and while I was there verified that without an active internet connection that the emails were still within thunderbird and completely accessible.

He called today, saying that his emails aren't showing up in thunderbird. I remotely connected to his computer to investigate and somehow, the emails were no longer in offline storage, they were gone completely. We were both aware that within 24 hours of him leaving the place of business that his email account was going to be deleted and once deleted he could no longer receive new emails from that email and would only be able to access the ones that we saved offline. I have no clue where the emails went, some of them are listed in the %appdata% roaming folder for thunderbird, but none of them are appearing in thunderbird and I can't open the file for the emails or the .msf folder files in thunderbird to get access to them. When I try to it just attaches it to an email and tries to send it.

I'm at a loss, hopefully you guys have some answer to this problem, whether it be hack the email server to get them back, or some sly way to open .msf folders(all the emails are in %appdata% roaming for thunderbird), but I can't think of anything. Please help and many thanks

 

Thunderbird problems

Right, so my gf's dad tried to back up his mail from Thunderbird to a network HDD by changing the location of the local folder for all his accounts, which is like 3 or 4. Now, none of his mail or accounts show up in Thunderbird and they aren't listed on the network drive. I was able to locate all the mail in its original location in AppData, but I don't know how to get it back to the way it was. Any ideas would help, thanks in advance.
