If you get an error indicating that your database is corrupted, the fastest way of getting eM Client running again is to restore your data from a backup.

This option will be available either from the window informing you about the results of the database check or from eM Client’s interface in Menu > File > Restore.

If you can’t access eM Client to restore the data, please follow the information below on starting with a new database to open the program.

To start with a new database, turn eM Client off and rename the "eM Client" database folder (default location is in hidden folders AppData\Roaming, the whole path is C:\Users\%username%\AppData\Roaming\eM Client) to e.g. ‘eM Client old database’.

Please note that eM Client must stay turned off during this process. Check for eM Client or mailclient.exe in the Task Manager and if you see a process with either of these names, end it before you proceed.

If you do not have a backup but still have all your data saved on the server, you will have to start with a new database, re-create your accounts from scratch and wait until the data is synchronized again.
