I created a Shared Inbox through the Exchange Admin Center in O365. Anyone I've set to &quot;Full Access&quot; permission can open the calendar of the Shared Inbox no problem. Also sending appointments to the mailboxes address is working. The problem is even though we've set Full Access permission the calendar cannot be shared out to other users. The &quot;share&quot; button is grayed out in Outlook as well as the OWA. Am i even going about this the correct way? Should i be using Public folders instead?
