Hi,
I have a mixed environment of Exchange 2003 and Exchange 2010. I have migrated all 1500 users to Exchange 2010. Some of the migrated users does not have My Calendar on their Outlook and OWA. The only solution is, i migrated few users back to Exchange 2003, add an appointment/item in their calendar and migrate to Exchange 2010. Somehow this is quite troublesome as i have alot of users. Can anyone help me out with this issue please..
Users No Calendar
Users With Calendar
