How do I receive meeting invitations as iCalendar attachments instead of Outlook Web App links?

To set these meeting invitations, you have to configure your Calendar settings on web view by doing the following:

1. Log in to the Office 365 Portal.
2. Open the Calendar.
3. Click the gear on the top right corner. The settings pane will pull out.
4. Click IPOP and IMAP under the Accounts tab in the Options pane on the left side of the screen.
5. Click Send invitations in iCalendar format under POP Options.
