Adding a 365 public shared calendar to Mac 2011 Outlook (public folded subscribe is grayed out)
I setup a public mailbox and public folder and then added a public calendar through Outlook 2016 (PC) I am able to add users and the PC clients on Outlook 2010 and 2016 can add to favorites and view the public calendar. I cannot get the mac outlook 2011 user to see the the calendar. I click on the Public folders button and see the name of the folder but it is grayed out along with the option to subscribe. I also don't see the public calendar.
Which leads me to the first question: Which version of Exchange do you run? Many key things were changed in Exchange 2013.
Another possible solution lies here.
Outlook for Mac 2016 is probably a better choice but, as my article on the app points out, it too has issues with "shared" folders.
My experience with both in our workplace shows that some workarounds were done by our sysadmins but it is still not a perfect solution.
