I am running exchange 2010 and ran into a small problem with a resource. The HR department has full access to a conference room which I've setup as a resource so it can be scheduled. A member of the staff accidentally placed a private appointment on the calendar. She can not delete it and neither can I even with full admin access. I've tried a number of things including assigning full owner permissions to both my account and the original users. I can see the appointment in there but it shows a small lock in the bottom right corner and no context menu appears when I click on it. This is the same for my exchange admin account, the original user, and other accounts that I've tried with owner permissions to the account. In past versions of exchange I could log in as the resource and remove it but I can't do that with a resource account in 2010. I'd appreciate any advice on this on!
