Missing Google calendar entries in Outlook

Hello

I have several Google accounts and want to use Outlook in Office 2011 to manage them on my mac.

I have purchased an Office 365 annual license and installed Office 2011.

I have set up my accounts and all the email is coming through.

However, I could not sync contacts - but I have resolved that by a tiresome export and import.

The remaining issue is my Outlook calendar. Only the meetings that have invites still in my inbox are showing. None of the (plenty of) other existsing calendar entries in my Google calendar are showing. Most of the existing entries are repeating occurances (if that makes any difference) also a number are appointments just for me rather than meetings with other attendees.

Also I notice that if I create a calendar event in Outlook it only shows there an does not appear in my Google calendar. I cant see which (if any) of the Google email accounts the Outlook calendar is associated with.

Any thoughts on how to resolve this? Quite possibly user error, though I think I followed the set up instructions correctly. 

Thnaks in advance,

Richard
