First time posting so hopefully I'm in the right area. There's one section of my employer that's been using exchange for several years and the plan is to migrate them to zimbra. Which they howl about(sigh). The current impasse is sending private email to people.
I tested it by sharing a folder with someone here and then having them send a private email to me. When they access the email in outlook they are unable to open it but in zimbra's webmail there is no restriction.

Is it possible to do this in zimbra? And if not are there any plans to implement this?
If this has been answered before I apologize, I did a few searches and couldn't find anything.
