I’ve just updated eM. Where are my folders with my emails??? Where are my old email ???

I had the same problem but managed to restore my system to just before the eM Client update which wiped my emails - in Windows 10, I searched for ‘System restore’ in the search bar next to the Windows icon. This led to ‘Create a restore point’ and it was then just a case of following the onscreen instructions. The emails were restored and my panic was over! I won’t be attempting to update eM Client again, at least until I’m assured that this issue has been fixed.

Hello Darek,
seems like you accidentally skipped the database migration.
Import your data using the Menu>File>Import>Import from eM Client 6 option.
