I created a company Calendar in the Public Folders, but for some reason, when I try to open it in Outlook 2010 from any user's email, including the account I created it with, I am having a problem adding it. I go to the Public Folder view, right click on the calendar, and select "Add to Favorites...". It then shows up in my favorites, but will not allow me to click on the check box to the left. I can see the calendar under "Other Calendars", but wasn't sure why that is the only way. I am trying to find the easiest way to allow users to add the company calendar to their calendar list.
