Google Calendar = Microsoft Office

Has anyone successfully been able to have all events created in Google Calendar to be represented in a separate Microsoft Office account?

In my org we have two email accounts, Google and MS Office. Google is our main account and MS Office is used by the rest of the company. We are the only one’s that use Google WS.

When the rest of the company wants to see our availability they check MS office and see not calendar events. I was wondering if anyone has been able to solve this by using API’s, App Script/Sheet or Third Party apps.

Thanks in advance!
