Optional

• 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 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.

Optional

Microsoft.Exchange.Data.Directory.Recipient.MessageFormat

The MessageFormat parameter specifies the message format for messages 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.

ModeratedBy

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The ModeratedBy parameter specifies the users who are responsible for moderating the messages sent to this mailbox. To designate more than one user, separate the users by using commas.

This parameter is required if you set the ModerationEnabled parameter to $true. If you leave this parameter blank, and a user is already specified as the manager of this mailbox, the ModeratedBy parameter is automatically set by the ManagedBy parameter of the mailbox. Otherwise, an error is returned.

ModerationEnabled

Optional

System.Boolean

The ModerationEnabled parameter enables or disables moderation for the mailbox. To enable moderation, set this parameter to $true. To disable moderation, set this parameter to $false.

The default value is $false.

This parameter is available for multi-tenant deployments. It isn't available for on-premises deployments. For more information about multi-tenant deployments, see Multi-Tenant Support.

The Organization parameter specifies the organization in which you'll perform this action. This parameter doesn't accept wildcard characters, and you must use the exact name of the organization.

OrganizationalUnit

Microsoft.Exchange.Configuration.Tasks.OrganizationalUnitIdParameter

The OrganizationalUnit parameter specifies the organizational unit (OU) to which the new contact is added. For example, redmond.contoso.com/contacts.

The OverrideRecipientQuotas parameter specifies that the recipient quotas for this mail contact can be overridden. Mail contacts that are part of a tenant organization will use the quotas defined in the tenant organization's service plan. Use this parameter to allow the command to skip the tenant-level recipient quotas check.

Note:
Using this parameter doesn't set quotas. You need to define the quotas for the mail contact using the Set-MailContact cmdlet.

PartnerObjectId

Optional

System.Guid

This parameter is reserved for internal Microsoft use.

PrimarySmtpAddress

Optional

Microsoft.Exchange.Data.SmtpAddress

The PrimarySmtpAddress parameter specifies the primary SMTP address for the mail contact. By default, the email address that is specified in the ExternalEmailAddress parameter is set as the PrimarySMTPAddress. If you specify a primary SMTP address by using this parameter, the command sets the EmailAddressPolicyEnabled attribute of the mail contact to $false, and the e-mail addresses of this mail contact aren't automatically updated based on e-mail address policies.

SendModerationNotifications

Optional

Microsoft.Exchange.Data.Directory.Recipient.TransportModerationNotificationFlags

The SendModerationNotifications parameter specifies whether status notifications are sent to users when a message they sent to the moderated distribution group is rejected by one of the moderators. You can specify one of the following values:

• Always
  
  
• Internal

Set this parameter to Always if you want notifications to be sent to all senders.

Set this parameter to Never to disable all status notifications.

The default value is Never.

UsePreferMessageFormat

Optional

System.Boolean
