In Outlook 2016 (running on Office 365 mail), If I highlight the "inbox" folder, the 'Items' count shows 95 but the 'Unread' count shows 91. If I log into the OWA, the Inbox matches with the 91. I don't know what the 4 items are.
Also, I am unable to mark all as read and see what remains due to this being a shared mailbox.

Just close Outlook and delete the OST file that is associated with mailbox. Start Outlook, it will synchronize the mailbox again and you shouldn't see these "extra" items anymore.

I tried the steps you suggested, however no change. I also built the same user profile on a totally different workstation and the same error was happening. – AlexM – 2016-05-16T13:34:30.040
Try toggling offline mode
