Windows calandar on Microsoft 650: Forward dating problem

[Petergmarsh]

I use Google calendar on a MAC air desk top synced to my iPad and my Microsoft 650 phone.
The problem is that calendar items entered on my Mac Air, if dated over 160 days forward will not sync to my Microsoft 650 phone. However recurring entries do show on the Microsoft 650.
How can this be rectified as without this forward information the calendar is not much use at all.
