I am attempting to get a conference room calendar to be managed by users. My searches have not turned up any relevant posts so here goes.

When I set them up as Admin's of the resources calendar, they do not have the ability to add appointments to the resources calendar, however when I set them up to be managers they do have this ability. Is this intended or a bug? it seems that the Admin's should be able to do everything the Managers can do as well as Administer that item.

Ubuntu 6.06 LTS Zimbra NE 5.0.9.
