Hi Ravikumar,
I went to the sharing settings of the calendar and sent an email to my Gmail account. When I received the email it had a XML file attached. I opened the xml file and found the ical information. I was able to use the URL provided and added the calendar and it syncs properly to my google account. Step by step below:
Under the calendars menu> hover over the calendar you want to share hit the three dots>Sharing and Permissions
Enter an email in the field provided.
Open your email account and the "You're invited to share this calendar" email open the XML file attachment. Find the following line of code:
<ICalUrl xmlns="http://schemas.microsoft.com/exchange/sharing/2008">https://outlook.office365.com/(THIS_IS_YOUR_CALENDAR_SHARE_URL).ics</ICalUrl>
Copy the https://outlook.office365.com/(THIS_IS_YOUR_CALENDAR_SHARE_URL).ics portion
Go to other calendars in your google calendar and hit the + button> Select From URL
Paste the URL and add the calendar
Hope this helps,
Adam
