We have a shared calendar that I need to add a user to. The option to share is greyed out. Exchange Server 2010, Outlook 2010 and 2013 (Same issue for me and another user. I have 2013, they have 2010). My account is set to "Owner" under the calendar Permissions properties.
I've tried it with "outlook.exe /safe" and that didn't do anything. It was suggested in this thread to "Also check full permission given on that mailbox to 'Self'." What does that mean?
What else can I do?
