I have set up several equipment accounts, similar to the way I currently have functioning room accounts set up, but some of my equipment accounts are not working as expected. The scenario I want to achieve is that a requestor of a piece of equipment receives a tenative email until the delegate has approved the request, then they receive an acknowledgement. This is working on all of my rooms, and also on some of my equipment, but on others, it is not. On the non-working equipment, as the delegate, I receive a message: "cannot open calendar folder for user ***. Operation failed. The odd thing is that I have several identically set equipment resources and several work, while others does not. Through group membership, I have set up the delegates and also added the group to have full access permissions on both . I have attached the settings for each of two pieces of equipment--one working, one not. I"m not sure where I have gone wrong, so any assistance would be much appreciated.
