I recently purchased (3) Office 365 seats for myself and my team. I am on a Mac. I have been using Google Calendar for my business calendar but now want to switch to Outlook. So far that has been no problem except that I cannot sync my personal Google Calendar with Outlook so that I can see everything in one interface. I have tried all the tutorials I can find and have spent 4+ hours on the phone with Microsoft. They are telling me I need an exchange server but I don't buy it. No one else online is telling me that an exchange server would solve the problem. It's as if my version of Outlook is flat out missing the shared (or internet) calendar functionality.
