Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Test-EdgeSynchronization cmdlet to diagnose whether the subscribed Edge Transport servers have a current and accurate synchronization status.

Test-EdgeSynchronization [-ExcludeRecipientTest <SwitchParameter>] [-FullCompareMode <SwitchParameter>] [-MaxReportSize <Unlimited>] [-MonitoringContext <$true | $false>] [-TargetServer <String>] <COMMON PARAMETERS>
Test-EdgeSynchronization -VerifyRecipient <ProxyAddress> <COMMON PARAMETERS>
COMMON PARAMETERS: [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example diagnoses the synchronization status of subscribed Edge Transport servers, outputs only the first 500 data inconsistencies, and generates events and performance counters for use by System Center Operations Manager 2007.

Test-EdgeSynchronization -MaxReportSize 500 -MonitoringContext $true

This example verifies the synchronization status of the single recipient kate@contoso.com.

Test-EdgeSynchronization -VerifyRecipient kate@contoso.com

The Test-EdgeSynchronization cmdlet is a diagnostic cmdlet that provides a report of the synchronization status of subscribed Edge Transport servers. You can use the VerifyRecipient parameter with this cmdlet to verify that a single recipient has been synchronized to the Active Directory Lightweight Directory Services (AD LDS) instance. The Edge Subscription process establishes one-way replication of recipient and configuration information from Active Directory to AD LDS.

This cmdlet compares the data stored in Active Directory and the data stored in AD LDS. Any inconsistencies in data are reported in the results output by this cmdlet.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "EdgeSync" entry in the Mail flow permissions topic.


Parameter Required Type Description




The VerifyRecipient parameter specifies a single recipient with which to verify the synchronization status. You identify the recipient by specifying a proxy address assigned to the recipient. The proxy address is the recipient's email address. The recipient verification test is mutually exclusive of the test that verifies synchronization of configuration data.




The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.




The ExcludeRecipientTest switch specifies whether to exclude validation of recipient data synchronization. If you include this switch, only the synchronization of configuration objects is validated. Validating that recipient data is synchronized takes longer than validating only configuration data. You don't have to include a value with this switch.




The FullCompareMode switch specifies whether a full comparison of the configuration data between Active Directory and AD LDS instance on the target Edge Transport server is performed. If you don't use this switch, a full comparison of replicated configuration data is skipped and the command only tests the Edge synchronization by verifying the replication cookie.




The MaxReportSize parameter specifies the total number of objects and properties listed in the results. The results output by this command include a list of all out-of-sync objects and properties in both AD LDS and Active Directory. If the directory services aren't synchronized, a large amount of data can result. If you don't specify a value for this parameter, the default value of 1,000 is used. The minimum value for this parameter is 1. The maximum value for this parameter is unlimited.




The MonitoringContext parameter specifies whether to include the associated monitoring events and performance counters in the results. Valid values for this parameter are $true or $false. The default value is $false. If you specify the value $true, the monitoring events and performance counters are included in the command results. Typically, you include the monitoring events and performance counters in the results when the output is passed to MicrosoftSystem Center Operations Manager (SCOM).




The TargetServer parameter specifies an Edge Transport server to initiate edge synchronization with. If omitted, all Edge Transport servers are synchronized.

You may want to use this parameter to specify a single Edge Transport server for synchronization if a new Edge Transport server has been installed or if that Edge Transport server has been unavailable for some time.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
