Calendar sharing no longer works on Mac desktop app
I've been demoing Office 365 to see if my company wants to switch to it but am finding issues for Mac users. Apparently the latest update in Dec broke calendar sharing on Mac 2016 desktop. If a user tries to share a calendar, it will no longer appear in shared calendars for the sharee. The support knowledge base instructions no longer match what the mac app now shows, so you can't do what it instructs. It does appear that the online/browser version still works, it's apparently just the desktop app that has been broken. Verified this with support.
