After installing Thunderbird on a new Lenovo Win10 laptop and configuring several email accounts, they all disappear each time I reboot or power up. Help!

I just bought a new Lenovo laptop with Windows 10. I downloaded Thunderbird and installed it. Then, I configured several email accounts and verified they were all working.

Each time I power down my laptop and power up again (or just reboot) and run Thunderbird, all of my email accounts are gone and I have to create them all over again. Why are they disappearing? It's as if I never created them.

Appreciate the help. This is really annoying.

Do you run the ccleaner tool? (I'm not suggesting you should, we just need to know)

Wayne, thanks so much for the reply. Yes, I use CCleaner, but as it turned out, that wasn't the problem.

The difficulty was caused by a flawed Win10 user account, created when I initialized the computer. My local computer repair shop caught the problem on boot-up. Nothing I defined with Firefox or Thunderbird was saved since the account "couldn't be located" by Windows.

Creating a new user account and deleting the old one fixed the problem. Ironically, the first account was setup using the Cortana voice assistant (so much for automation!) and the second one was created manually.

Everything is working fine now.

That is very odd. So you know what was wrong with the first Windows account?
