Here are features that G Suite Sync for Microsoft® Outlook® (GSSMO) doesn't fully support in Outlook Calendar. These features either aren't available in Outlook, or they might not work as you'd expect.
|Tentative or Out of Office status||Choosing Tentative or Out of Office status for a calendar event appears as Busy to other users viewing your status. This is because Google Calendar supports only Free or Busy status, not these other alternatives.|
|Calendar attachments||If you attach a document, contact, or other item to a calendar event in Outlook, you'll see the attachment in your own Outlook calendar, but other attendees won't see it in theirs. This is because attachments aren't synchronized with other people's Google calendars. Additionally, recipients of the event invitation will receive an email with the name of the event as the subject and the attached item, yet without any RSVP options.|
|Moving or copying events between calendars||You can't drag an event from one calendar to another in Outlook, as you can when using Outlook with Microsoft Exchange.|
|Saving event updates without sending||If you create or update an event in Outlook and choose not to send the change to attendees (by closing the event window and choosing not to send), attendee calendars update anyway. This is because event data always synchronizes with other people's calendars whether or not you send updates from Outlook.|
|"Share my Calendar" link||You can share calendars from GSSMO, but you don't use the "Share my Calendar" link (which isn't available). Instead, set up sharing by signing in to your Google Calendar account in a web browser. For details, see Sharing and delegation.|
|"Deleting" calendar folders||You can delete a calendar folder from Outlook to remove it from your Calendar Navigation Pane. But the calendar isn't deleted from your account. It's just no longer synchronized with Outlook. To delete the calendar completely, you must sign in to your Google Calendar account and delete it there. For details, see Delete a calendar.|
|Rich content in calendar events||
You can add rich content such as links, formatted text, and tables to a calendar description in Outlook. But if you're using Outlook 2016, save the events with rich text format. If you save the events as HTML, the formatting won't synchronize with other users' calendars and they will only see plain text.

|Calendar invitations sent to a POP or IMAP account||If you create a POP or IMAP account in your Outlook profile, calendar invitations sent to that account will not appear on your primary Outlook calendar (as they would with Exchange). GSSMO can only update your calendar with invitations sent to your G Suite account.|
