I've poked around the documentation and can't seem to see this functionality.
With Meeting Maker, you can have two types of proxies, essentially. "Willing" and "Unwilling".
You can happily, willingly, share your calendar with whomever you want.
By the same token, though, you can set it up so that "your boss", for example, has access to your calendar, and you're not capable of revoking that access, because it's done at a level "above your head" so to speak.
Is that capability present in Zimbra and I'm just not seeing it? How would an admin go about setting that up for someone?
