Cannot install & Open App


When I try to install on Windows 10… it gives me this error:
We encountered a problem with your local email database (mailsync: 0)

To Reproduce…

Steps to reproduce the behavior:

A. Reinstalling MailspringSetup.exe
B. Reopening it again…

Expected Behavior

The app should install and open like normal.



  • Windows 10 Home - OS build: 19044.1766
  • Mailspring Version: Tried 1.10.3 and 5 older ones before it. None worked.

Additional Context

Just can’t open the app without this popping up. See screenshot.
Works fine on Linux, but on Windows 10, just doesn’t want to open…
