We are using Exchange 2003. We have blackberries too. We use to be able to sync the blackberries to a public calendar in which only one person had OWNER rights to (all other users were setup w/ Permission Level of REVIEWER only. After operating like this for nearly a year, the blackberry sync process began to fail by aborting half way through the sync process. Once we changed these user's permission level to OWNER it was fixed. I need to get everyone back to REVIEWER status b/c they're now making global changes which are not acceptable to the organization.
Any advice on what's happening here and how I can get this to work like it once did?
