Configure Group Metrics
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
MailTips that provide information about the size of distribution groups and dynamic distribution groups rely on group metrics data. Group metrics data is generated on designated Mailbox servers and is copied to Client Access servers using the Microsoft Exchange File Distribution Service. For more information about group metrics, see Understanding Group Metrics.
You can enable or disable group metrics generation on a Mailbox server and configure the time when group metrics data is generated.

Prerequisites
Group metrics data is only used for MailTips. Make sure that group metrics MailTips are enabled in your organization. For detailed steps, see Configure Organizational Settings for MailTips. To learn more about MailTips, see Understanding MailTips.
Use the Shell to enable or disable group metrics generation
You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Group metrics" entry in the Mailbox Permissions topic.
Note
You can't use the EMC to enable or disable group metrics generation.
Note
By default, group metrics data is generated on any server responsible for generating the offline address book (OAB). The configuration shown in this example is only necessary for organizations that don't use OABs. For more information, see Understanding Group Metrics.
You use the Set-MailboxServer cmdlet to enable or disable group metrics generation on a Mailbox server. This example forces group metrics generation on server MBX1.
Set-MailboxServer MBX1 -ForceGroupMetricsGeneration $true
This example disables group metrics generation on server MBX1.
Note
If this server is generating OABs, it will continue to generate group metrics data. This example is only applicable for servers that don't generate OABs.
Set-MailboxServer MBX1 -ForceGroupMetricsGeneration $false
Note
In the release to manufacturing (RTM) version of Microsoft Exchange Server 2010, this parameter was named GroupMetricsGenerationEnabled.
For detailed syntax and parameter information, see Set-MailboxServer.
Use the Shell to configure the group metrics generation time
You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Group metrics" entry in the Mailbox Permissions topic.
Note
You can't use the EMC to configure the group metrics generation time.
You use the Set-MailboxServer cmdlet to configure the time of day when group metrics data is generated on a Mailbox server. You must use the 24-hour clock notation (HH:MM) when specifying the generation time. These examples configure group metrics generation on servers MBX1 and MBX3 to occur at 11:30 P.M. and 3:00 A.M. respectively.
Set-MailboxServer MBX1 -GroupMetricsGenerationTime 23:30
Set-MailboxServer MBX3 -GroupMetricsGenerationTime 03:00
For detailed syntax and parameter information, see Set-MailboxServer.
