Google Calendar issue

Google Calendar issue

Hi,

Having an issue with our calendar sync (I think). We keep getting duplicate events within Zoho CRM. Additionally, we will see that these events are showing created by Person B - when in reality they were created by Person A in Zoho. 

I think I know why this issue is occuring.... we have a two-way sync between our users and their google calendars. Our company shares our google calendars with each other as well. So I think when users navigate within GCalendar and turn their coworkers calendar views on/off, the events within those calendars are syncing in and out of Zoho CRM. As you can imagine this is a very annoying issue, but we need to maintain access to eachothers calendars to schedule events, but also want the events to populate within Zoho (If on our company calendar). 

Any advice into how we may be able to resolve this issue?
