I changed by data location to \Main\eM Client – now I cannot find the old data in User\appdata\roaming\microsoft\eMClient
If you changed your database directory a new blank database was created in the new directory. You can find the old database in Users\UserName\AppData\Roaming\eM Client (or eM Client Preview if you’re using V7 Beta). We do not store data in the microsoft directory.
Hope this helps.
