All my Mail Accounts disappeared

[Windows Central Question]

I signed into my desktop at home today and opened my Windows 10 Mail App and all my Mail Accounts are gone. I did install the new update on Tuesday but everything was working fine yesterday (Wednesday). Any ideas?

I had the same problem with my Lumia recently. It happened after the phone froze and restarted itself and I'm not sure if the app was not updated either. But re-entering the accounts worked so... Seems You're not alone but the solution is that simple...
