MacAttachmentFormat

Optional

Microsoft.Exchange.Data.Directory.Recipient.MacAttachmentFormat

The MacAttachmentFormat parameter specifies the Apple Macintosh Operating System attachment format for messages that are sent to the mail contact. The valid values for this parameter are:

• 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 that are sent to the mail contact. 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 that are sent to the mail contact.

The valid values for this parameter are:

• Text
  
  
• Mime
  
  

By default, this parameter is set to Mime.

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.

Microsoft.Exchange.Configuration.Tasks.OrganizationalUnitIdParameter

The organizational unit to which the new contact is added. For example, redmond.contoso.com/contacts.

Use this parameter to specify the primary SMTP address for the mail contact. By default, the primary SMTP address is generated based on the default e-mail address policy. If you specify a primary SMTP address by using this parameter, the cmdlet will set the EmailAddressPolicyEnabled attribute of the mail contact to $false, and the e-mail addresses of this mail contact will not be automatically updated based on e-mail address policies.

The UseRusServer parameter instructs the command to use the specified Mailbox server on which the Address List service is running to obtain and then set mailbox and Active Directory user attributes.

The Address List service is a component in the Exchange System Attendant service. The Address List service creates and maintains Exchange-specific attribute values in Active Directory. You can use the Address List service to update recipient objects in a domain by using specific information, such as address list membership and e-mail addresses.

The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf parameter.
