I am using Zimbra OS 6.0.0, and I am having the following problem:
My users that have access to more than one mailbox in their web client, are not able to select the folders whenever they try to create a "File Into Folder" filter.
The access to more than one mailbox is done using mailbox relationships - Mailboxes: Sharing vs. Relationships » Zimbra :: Blog
Did anyone experience this and has a solution?
