Shared Office 365 calendars not showing up in iCal

We are using Microsoft's Office 365 and have users with a variety of devices and applications (Mac/iCal/Mail, Windows/Outlook, iPhone, Android, etc.).


I am the administrator of the Exchange accounts. I have created four calendars that are viewable by everyone within our organization (just general "company-wide calendars").


Users with Outlook are able to view those shared calendars just fine. However, I'm not able to add the shared calendars with users using iCal.


If I add them as a delegate, they can see all my calendars, but if I just share the calendar, they get a "no access" error.


Here's where I'm setting the shared calendar permissions. I've tried setting them as Reviewer, setting the Default as Reviewer, and setting them as Owner.


Because it works fine in Outlook, I'm wondering if it's an iCal problem. For cross-referencing purposes, here's my issue at Office 365's community: Shared calendars not showing up in Apple iCal

OS X Mountain Lion (10.8.2)

This is how I figured out how to get this to work. My company uses Outlook 365 Exchange. My co-worked shared his calendar with me. It wasn't showing up in Mac Calendar, or iCal, whatever you want to call it, in Yosemite. It shows up fine when I log into the web client for Outlook 365, so I know its there.


To solve it, in calendar if you go to preferences, accounts, delegation, then click add, type the person's exchange e-mail address, it will load and populate their calendar as a new calendar in the Mac calendar app.


That being said, the Mac calendar app is really not up to par for business. I'd encourage Apple to STRONGLY consider Enterprise users next time around, otherwise we'll all just download Outlook 2016 and use that instead.

This didn't used to be a problem, but it has surfaced recently. I have no idea what has changed. I can see other people's calendars fine through the browser connecting to Office 365, using a PC, and using Outlook for Mac. But no longer with Mac Calendar.


I am running MacOS Sierra (10.12.1) and Calendar 9.0 and using Business Office 365's hosted Exchange Server. All Office 365 services are currently up, according Microsoft.


But when I try to add a delegate (Calendar > Preferences > Accounts > Exchange > Delegation > + ), entering a person's name does not trigger a search on the server. It used to find people as I typed and I could pick them off the list. But not any more. If I enter the person's name and then just hit the enter key (i.e. force a search), I get an error message: You can't access the account of "xxxx" because "xxxx" wasn't found on the server.


Clicking the "Edit" button to add someone to the list of people who can access my account produces the same problem.


I have tried deleting the whole Exchange account from my mac and then re-adding it. Still no joy.


Microsoft just say Mac Calendar isn't supported so i should use Outlook... Apple say it's Microsoft's fault.
