I get this: Data corrupt, Property validat failed. Prop = [0x3a11001f] Surname Err = too long. value is 2002. Client 7.1.31849.0, Win 7Pro.

I get this in Log:
MailClient.Storage.Application.ItemOperationException: Data is corrupt., Property validation failed. Property = [0x3a11001f] Surname
Error = The length of the property is too long. The maximum length is 256 and the length of the value provided is 2002…
eM client 7.1.31849.0 on Win 7Pro. What does this mean?

It means that you can only have 255 characters in the surname field. (Your error says 256 is the maximum, but I think that is incorrect) Apparently eM Client thinks you have one or more contacts that have 2002 characters.

You can repair the database manually to see if that is the problem. Close eM Client and run C:\Program Files (x86)\eM Client\ DbRepair.exe

Thanks, Gary! Worked like a charm…

Yeah, sorry I did not see your question before. :slight_smile:

No problem - it was just an irritating piece of {something}…

BTW, is there a way to have backups on schedule automatically?

Yes, go to Menu > Tools > Settings > General > Backup
