Windows 10: Wiped out all my Thunderbird accounts..

Here's one for you I bet you haven't heard yet.

A window popped up saying my SD card I use to run portable apps off had errors and would I like Windows to correct it. I naturally said yes, and Windows came back with another poppup saying the drive was repaired. I then proceeded to check my mail using Tbird on the drive. Tbird came up as if it was just installed! I am not a happy camper, I had 7 email addresses along with archived folders going back to 2016. What could have happened? All other portable programs and files are fine.

Accounts in windows 10 and Thunderbird


After upgrading to windows 10 I added my outlook.com account to "mail" in windows 10. I didn't like it, and had trouble using the "sync" function but eventually got it synced and folders rebuilt and files over to it. I have now installed Thunderbird and like that program much better and have imported all my files and folders and contacts.
Question: Can I now remove my outlook.com account from "mail" in windows 10 ? Or will that wipe all info I imported to and using with Thunderbird? And second, how to I remove that account in mail, I don't see that option listed anywhere. Thank in advance for any help or suggestions.

 

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.
