ClearCategories

Optional

System.Boolean

This parameter specifies whether to clear Microsoft Office Outlook categories during content conversion. The default value is $True.

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm parameter causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm parameter.

DSNConversionMode

Optional

Microsoft.Exchange.Data.Transport.DSNConversionOption

The DSNConversionMode parameter controls how Exchange handles DSNs that are generated by earlier versions of Exchange or non-Exchange messaging systems. You can specify one of the following values for this parameter:

• UseExchangeDSNs
  
• PreserveDSNBody
  
• DoNotConvert
  

If you set this parameter to UseExchangeDSNs, Exchange will convert the DSNs to the Exchange 2007 DSN format. Any customized text or attachments that the original DSN has will be overwritten.

If you set this parameter to PreserveDSNBody, Exchange will convert the DSNs to Exchange 2007 DSN format, but the text in the DSN message body will be retained.

If you set this parameter to DoNotConvert, Exchange will not modify the DSN, and will deliver it as a standard message.

The default value is UseExchangeDSNs.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

To specify the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to the Active Directory directory service, include the DomainController parameter on the command. The DomainController parameter is not supported on computers that run the Edge Transport server role. The Edge Transport server sole reads and writes only to the local ADAM instance.

GenerateCopyOfDSNFor

Optional

Microsoft.Exchange.Data.MultiValuedProperty

This parameter controls the non-delivery reports (NDRs) that are copied to a mailbox by specifying the delivery status notification (DSN) codes that you want to monitor. You must configure the list of monitored DSNs on one Hub Transport server and locally on each Edge Transport server in your Exchange 2007 organization.

On a Hub Transport server, NDRs are copied to the mailbox that is assigned to the Microsoft Exchange Recipient. On Edge Transport servers, NDRs are copied to the mailbox that is assigned to external postmaster address.

DSN codes are entered as x.y.z and are separated by commas. By default, the following DSN codes are monitored:

• 5.4.8
  
• 5.4.6
  
• 5.4.4
  
• 5.2.4
  
• 5.2.0
  
• 5.1.4
  

Although these DSN codes are monitored by default, the associated NDRs aren't copied to the Microsoft Exchange Recipient or to the external postmaster address if no mailbox is assigned to the Microsoft Exchange Recipient or to the external postmaster address. By default, no mailbox is assigned to the Microsoft Exchange Recipient or to the external postmaster address.

To assign a mailbox to the Microsoft Exchange Recipient, use the MicrosoftExchangeRecipientReplyRecipient parameter in the Set-OrganizationConfig cmdlet. To assign a mailbox to the external postmaster address, create a new mailbox that is named "Postmaster". The default e-mail address policy of the Exchange organization should automatically add an SMTP address of postmaster@<Authoritative domain> to the mailbox.

To enable the transport dumpster, the value of the MaxDumpsterSizePerStorageGroup parameter must be greater than 0, and the value of the MaxDumpsterTime parameter must be greater than 00:00:00.

MaxReceiveSize

Optional

Microsoft.Exchange.Data.Unlimited

This parameter specifies the maximum message size that can be received by recipients in the organization. The default value is 10 MB. When you enter a value, qualify the value with one of the following:

• KB (kilobytes)
  
• MB (megabytes)
  
• GB (gigabytes)
  

Unqualified values are treated as kilobytes. The valid input range for this parameter is 0 to 2097151 kilobytes. If you enter a value of Unlimited, no limit is imposed on the message size that can be received by recipients in the organization.

MaxRecipientEnvelopeLimit

Optional

TLSReceiveDomainSecureList

Optional

Microsoft.Exchange.Data.MultiValuedProperty

This parameter specifies the domains from which you want to receive domain secured e-mail by using mutual Transport Layer Security (TLS) authentication. To fully support mutual TLS authentication, you must also perform the following steps:

• Enable Domain Security (Mutual Auth TLS) and the TLS authentication method on the Receive connectors that receive messages from the domains that you specified with the TLSReceiveDomainSecureList parameter.
  
• Specify the domains to which you want to send domain secured e-mail by using the TLSSendDomainSecureList parameter.
  
• Enable Domain Security (Mutual Auth TLS) on the Send connectors that send messages to the domains that you specified in the TLSSendDomainSecureList parameter.
  

Multiple domains may be separated by commas. The wildcard character (*) is not supported in the domains that are listed in the TLSReceiveDomainSecureList parameter or in TLSSendDomainSecureList parameter. The default value for both parameters is an empty list ({}).

TLSSendDomainSecureList

Optional

Microsoft.Exchange.Data.MultiValuedProperty

This parameter specifies the domains from which you want to send domain secured e-mail by using mutual TLS authentication. To fully support mutual TLS authentication, you must also perform the following steps:

• Enable Domain Security (Mutual Auth TLS) on the Send connectors that send messages to the domains that you specified in the TLSSendDomainSecureList parameter.
  
• Specify the domains from which you want to receive domain secured e-mail by using the TLSReceiveDomainSecureList parameter.
  
• Enable Domain Security (Mutual Auth TLS) and the TLS authentication method on the Receive connectors that receive messages from the domains that you specified in the TLSReceiveDomainSecureList parameter.
  

Multiple domains may be separated by commas. The wildcard character (*) is not supported in the domains that are listed in TLSSendDomainSecureList parameter or in TLSReceiveSecureList parameter. The default values for both parameters an empty list ({}).

VerifySecureSubmitEnabled

Optional

System.Boolean

The valid values for this parameter are $True or $False. The default value is $False. The VerifySecureSubmitEnabled parameter verifies that e-mail clients that are submitting messages from mailboxes on Mailbox servers are using encrypted MAPI submission. By default, Outlook 2007 uses encrypted MAPI submission to send messages from Exchange 2007 mailboxes. By default previous versions of Outlook do not use encrypted MAPI submission to send messages from an Exchange mailbox. If the VerifySecureSubmitEnabled parameter is set to the value of $True, and Outlook 2007 is used to submit the message, the message is marked as secure. If a previous version of Outlook is used to submit the message, the message is marked as anonymous. If the VerifySecureSubmitEnabled is set to the value of false $False, all MAPI message submissions are marked as secure. Messages that are submitted from mailboxes on the Mailbox server by using any MAPI client are not checked for encrypted MAPI submission. If you use previous Outlook versions in your Exchange organization, you should set VerifySecureSubmitEnabled to $False.
