I'm using Zimbra Desktop 7.2 and I used to move in Local Folders single e-mails.

Now I need to move entire folders from Server to Local folders.
I tried to do this with diverse accounts and diverse folders but very often I lost some e-mails and I had to restore them from previous backups.
The strange thing is that Zimbra Desktop doesn't report any error.

Is it a bug of this version?
How can I solve the problem?

It is a big issue for me and for my costumers so I hope you'll be able to help me soon!

Thank you very much!
