Calendar Error: Calendar' failed due to the following error: Object reference not set to an instance of an object

Hello,

I am using Google Calendar to view my own calendar as well as calendars belonging to my colleagues. I frequently (almost every time I hit sync) receive the following error:

[Google Calendar] Synchronizing folder ‘Xxxxx@xxxxxxxxx.org/Calendar’ failed due to the following error: Object reference not set to an instance of an object.

When I receive this error message, some of the items on my/others’ calendars appear in emClient, while some do not. It varies, but maybe 75% of the calendar items appear, but many are missing.

Oddly, I also use em Client to view my personal Gmail calendar and never have any such issues.

Any help you all can provide?
