I can't seem to access other calenders from my Office365 organisation on my Windows Phone 8. I was previously able to do this with Google Apps.
I've searched the web and on here, but can't find any how to do it - The MS sales page indicates it's possible. http://office.microsoft.com/en-gb/business/office-365-business-email-and-shared-calendar-services-FX102996755.aspx.
I may be missing something incredibly obvious, but I can't see it at the moment!
