I experienced the following problem, using the Zimbra Connector 5.0.10GA:
I have a folder located in a shared mailbox, I need to move the folder to my own mailbox, then I receive an error fro Outlook.

After further investigations, I tried to to the same operation by means of the IMAP protocolo using thunderbird: again, it fails.

Even in the Web client I get an error if I try to do the very same operation, simply it is not possible to transfer entire folders from a shared mailbox to my own.

I gave myself admin permission when I shared the mailbox, so it doesn't appear as a permissions issue.

Is it just a design limitation, or could it be signaled as a Bug ? I searched various topics in the forum, but nobody seems to come out to a solution.
