FirstName

Optional

System.String

The FirstName parameter specifies the first name of the mail user.

ImmutableId

Optional

System.String

The ImmutableId parameter is used by GAL synchronization (GALSync) and specifies a unique and immutable identifier in the form of an SMTP address for an Exchange mailbox used for federated delegation when requesting Security Assertion Markup Language (SAML) tokens. If federation is configured for this mailbox and you don't set this parameter when you create the mailbox, Exchange creates the value for the immutable ID based upon the mailbox's ExchangeGUID and the federated account namespace, for example, 7a78e7c8-620e-4d85-99d3-c90d90f29699@mail.contoso.com. You must set the ImmutableId parameter if Active Directory Federation Services (AD FS) is deployed to allow single sign-on into an off-premises mailbox 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 a cross-premises Exchange deployment scenario.

• BinHex
  
  
• UuEncode
  
  
• AppleSingle
  
  
• AppleDouble
  
  

By default, this parameter is set to BinHex. The acceptable values for the MacAttachmentFormat parameter are dependent on the MessageFormat parameter. If the MessageFormat parameter is set to Text, you can only use BinHex or UuEncode values for this parameter. If the MessageFormat parameter is set to Mime, you can only use BinHex, AppleSingle, or AppleDouble values for this parameter.

MessageBodyFormat

Optional

Microsoft.Exchange.Data.Directory.Recipient.MessageBodyFormat

The MessageBodyFormat parameter specifies the message body format for messages sent to the mail user. The valid values for this parameter are:

• Text
  
  
• Html
  
  
• TextAndHtml
  
  

By default, this parameter is set to TextAndHtml.

The MessageFormat and MessageBodyFormat parameters are interdependent. If the MessageFormat parameter is set to Mime, the MessageBodyFormat parameter can be set to any valid value. 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.

MessageFormat

Optional

Microsoft.Exchange.Data.Directory.Recipient.MessageFormat

The MessageFormat parameter specifies the message format for messages sent to the mail user.

The valid values for this parameter are:

• Text

The MessageFormat and MessageBodyFormat parameters are interdependent. If the MessageFormat parameter is set to Mime, the MessageBodyFormat parameter can be set to any valid value. However, if the MessageFormat parameter is set to Text, the MessageBodyFormat parameter can only be set to Text. Therefore, if you want to change the MessageFormat parameter from Mime to Text, you must also change the MessageBodyFormat parameter to Text.
