When syncing attendees between Outlook and Google events there
are a number of considerations that directly affect the synchronization
of this information given the differences between Outlook and

managed attendee to it's SMTP counterpart which is required
when adding attendees to an Outlook event. In this case the
attendee entry cannot be synced.
Because of how Outlook handles accepting invites
where it deletes and creates a new accepted event it is
recommended to use the option to
only sync meeting
events that have been accepted
. This avoids the
scenario where the Google invite could be inadvertently
declined as a result of Outlook deleting the original invite
when accepted in Outlook.
If your Outlook account or Gmail email address is listed
as the organizer then the event attendees will sync between
the two calendars. This is most basic scenarios when syncing
organizer + attendees.
Please be careful here because if the Outlook and Google
account email addresses are different
you will create a scenario where the meeting shows as organized
from two different email addresses.

not sync the attendee list if the Google account
is not listed as an attendee on the Outlook event. You can
override this behavior using the option to allow the Google
account to impersonate the Outlook account which allows the
sync to assume your Google account is on the attendee list. This option should be used carefully.
