-This parameter is available only in the cloud-based service.

-The ExternalInOutlookEnabled parameter specifies whether to add identifiers to messages from external senders in Outlook on the web (formerly known as Outlook Web App). Valid values are:
-
-- $true: External senders are identified as external in list view and the reading pane.
-
-- $false: External senders are not identified as external. This is the default value.
-
-Whether the sender's domain is considered internal or external is controlled by the Set-AcceptedDomain cmdlet.
