Outlook 2010 won't open Exchange 2010 Public Calendars

Hello, I have 1 user on Outlook 2010 who cannot open 2 Public Calendars, but he's able to open a 3rd one. All three were created at the same time with the same permissions. I gave him Owner permissions, but this hasn't worked.


I haven't heard of anyone else with issues and most have the Author permission. What can I do to fix this?



Thank you,



Mike
