Microsoft Outlook, which is part of the Microsoft Office professional software suite, includes a calendar tool that can be used to schedule events and plan meetings. The Google Calendar service provides similar functionality, and you can transfer data between the two systems. To share your entire Outlook calendar with your Google Calendar account, you must export the data from Outlook and then import it into Google Calendar.
Launch the Microsoft Outlook application and go to the "Calendar" tab in the lower-left corner of the window.
Highlight your primary calendar from the My Calendars list on the left side of the window.
Go to the "File" menu and choose "Save As."
Enter a name for the exported calendar file and then click "More Options."
Use the Date Range and Detail fields to specify how much data you want to export for use in Google Calendar.
Click "OK" and "Save" to export your Outlook calendar data.
Open a Web browser and log into your Google Calendar account.
Click on "Calendar Settings" in the top toolbar.
Go to the "Calendars" tab and click on the "Import Calendar" link.
Click the "Browse" button, highlight the file you just exported from Outlook and then click "Open."
Select the Google Calendar where you want to store the data from Outlook and click "Import" to complete the process.
