You must set the ImmutableId parameter if Active Directory Federation Services (AD FS) is deployed to allow single sign-on into off-premises mailboxes and AD FS is configured to use a different attribute than ExchangeGUID for sign-on token requests. Both, Exchange and AD FS must request the same token for the same user to ensure proper functionality for cross-premise Exchange organizations.

However, if the MessageFormat parameter is set to Text, the MessageBodyFormat parameter can only be set to Text. Therefore, if you want to set this parameter to Html or TextAndHtml, you must also set the MessageFormat parameter to Mime.
