How To Guide For Sharing Office 365 Calendar To A Gmail User

We came across an issue related to the sharing of calendars with Office 365 and Gmail calendar, for which we found a solution that we would like to share with you.

Here is how we did it:

Log into Office 365 Portal and view Calendar. Right-click to “share calendar”.

Choose the Share options you want …either full, limited, or availability. All are view only options only

This example is availability only shared to a Gmail user


The Gmail user will get an email notifying her to add a calendar to their outlook.


The user clicks on the second link to subscribe to O365 calendar

After clicking on the link, the user will get a confirmation prompt



When the user clicks yes, the calendar is automatically added to outlook Calendar pane.
