Use the Test-MRSHealth cmdlet to test the health of an instance of the Microsoft Exchange Mailbox Replication service.

Test-MRSHealth [-Identity <ServerIdParameter>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-MaxQueueScanAgeSeconds <Int32>] [-MonitoringContext <$true | $false>] [-WhatIf [<SwitchParameter>]]

The Microsoft Exchange Mailbox Replication service runs on Client Access servers. This command ensures that the Mailbox Replication service is running and that it responds to a remote procedure call (RPC) ping check.

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 "Mailbox move" entry in the Mailbox Permissions topic.


Parameter Required Type Description




The Confirm switch 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 switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that retrieves data from Active Directory.




The Identity parameter specifies the server on which to perform the health test. If you don't specify the server, the command runs on the server to which you're connected.




The MaxQueueScanAgeSeconds parameter specifies the threshold for the last queue scan property. If the time stamp on the last queue scan property is older than the value specified by this parameter, an error event is created that shows the Mailbox Replication service isn't scanning mailbox database queues. The default value is 1800 seconds (30 minutes).




The MonitoringContext parameter specifies whether the results of the command include monitoring events and performance counters. The two possible values for this parameter are $true or $false. If you specify $true, the results include monitoring events and performance counters in addition to the information about services.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, 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 switch.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.

This example tests the health of the Mailbox Replication service on all Client Access servers.
