Is there a possiblilty the save the mails automatic. Now I have set the backup each day but in the backup I can't see or read the mails

Hello, unfortunately it is not possible to regularly export your emails into the default email message format. You can archive your items using the automatic archiving tool in application settings, however note this option will only move your messages from the server folder into local folders in your application database. In order to view it out of eM Client the items would need to be exported.

It’s safer to keep a copy of your messages on the server, in order to keep a proper backup of your data and keep your items synchronised with the offline client.

Regards,
