I have a user in my organization that is complaing that some users are unable to see her calendar. She wants her peers and managers to see the free/busy (AvailabilityOnly) schedule. Below is an example of how this has become an issue.
UserA wants to her share calendar. UserA adds UserB to share permissions window within Outlook as "Free/Busy." UserB cannot see any information on UserA calendar. UserA changes share permissions to Reviewer. UserB can see UserA calendar, but it now shows full details. UserA changes permissions to show Free/Busy again. UserB cannot see anything on calendar.
To makes things more strange, UserC, UserD, UserE...UserN have Free/Busy permissions on UserA calendar. Each can see UserA calendar just fine.
I have seen a lot of forums and posts on calendar sharing, but I have not seen anything that would give a clear cut answer to the problem we are facing. Any help would be appreicated.
Environment: WinServer 2008 R2, MS Exchange 2010, Outlook 2010
