I have some clients I have recently migrated to my exchange.
For some reason I cannot use Calendar Sharing for them OR Inbox sharing.
On my own account & users accounts in my domain, there is no problems.
On my outlook (2003) Above calendars there is blue text which reads "share my calendar" or alternatively, you can right click on calendar & select "sharing".
However, the "share my calendar" text does not appear for my clients & if you right click on calendar "sharing" is greyed out. "open a shared calendar" does appear.
How do I enable calendar sharing & or inbox sharing. I gahter the problem is related.
