Hello everyone I meet problem to edit calendar item. Some users are migrated from notes. They don’t meet problem to create new calendar. They edit it and meet error “you don’t have permission for these items”. Our system :windows 2008 R2 exchange 2007 sp3

Do they have enough permission to edit the calender and still you are getting the error message? what level of permission they are having? is that permission granted at the server side or outlook level? Grant access permission at the server side and reconfigure the outlook profile Thank you
