I have a user who would like to have someone else set up as a delegate to view/modify his calendar. He already has 2 other people that have this permission and it works for them. When I attempt to add this new person as a delegate, I select her as a delegate and give her Editor permission. I click Ok, and then when I go back in to check, her permission is set back to none.

I have tried giving her every type of permission, they all revert back to none.

I have tried adding another random person, the same thing happens.

He is using Outlook 2010; I thought that might be the problem as this is the first time we have tried to add a delegate after upgrading to 2010. I logged him into another computer with Outlook 2000, and tried to set the permissions that way. The same thing happened again.

I tried giving a user delegate access to my calendar, it worked fine for me.

I have found nothing about this on Google, so I am hoping someone here might know what is going on.

We are running an Exchange 2003 server running on Windows 2003 Enterprise.

Thanks!
