Description
The Set-DatabaseAvailabilityGroup cmdlet enables you to manage DAG properties that can't be managed from the Exchange admin center (EAC), such as configuring network discovery, selecting the TCP port used for replication and enabling datacenter activation coordination (DAC) mode.
DAG property values are stored in both Active Directory and the cluster database. Because some properties are stored in the cluster database, the underlying cluster for the DAG must have quorum to set the properties for:
- ReplicationPort
- NetworkCompression
- NetworkEncryption
- DiscoverNetworks
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
Set-DatabaseAvailabilityGroup -Identity DAG1 -WitnessDirectory C:\DAG1DIR
This example sets the witness directory to C:\DAG1DIR for the DAG DAG1.
Example 2
Set-DatabaseAvailabilityGroup -Identity DAG1 -AlternateWitnessDirectory C:\DAGFileShareWitnesses\DAG1.contoso.com -AlternateWitnessServer CAS3
This example preconfigures an alternate witness server of CAS3 and an alternate witness directory of C:\DAGFileShareWitnesses\DAG1.contoso.com for the DAG DAG1.
Example 3
Set-DatabaseAvailabilityGroup -Identity DAG1 -DatabaseAvailabilityGroupIpAddresses 0.0.0.0
This example configures the DAG DAG1 to use DHCP to obtain an IP address.
Example 4
Set-DatabaseAvailabilityGroup -Identity DAG1 -DatabaseAvailabilityGroupIpAddresses 10.0.0.8
This example configures the DAG DAG1 to use a static IP address of 10.0.0.8.
Example 5
Set-DatabaseAvailabilityGroup -Identity DAG1 -DatabaseAvailabilityGroupIpAddresses 10.0.0.8,10.0.1.8
This example configures the multi-subnet DAG DAG1 with multiple static IP addresses.
Example 6
Set-DatabaseAvailabilityGroup -Identity DAG1 -ReplicationPort 63132
This example configures TCP port 63132 as the port used by replication for the DAG DAG1.
After changing the default replication port for a DAG, you must manually modify the Windows Firewall exceptions on each member of the DAG to allow communication to occur over the specified port.
Example 7
Set-DatabaseAvailabilityGroup -Identity DAG1 -DatacenterActivationMode DagOnly
This example configures the DAG DAG1 for DAC mode.
Example 8
Set-DatabaseAvailabilityGroup -Identity DAG1 -AutoDagVolumesRootFolderPath C:\ExchVols -AutoDagDatabasesRootFolderPath C:\ExchDBs -AutoDagDatabaseCopiesPerVolume 4
This example configures the DAG DAG1 for AutoReseed using custom mount point paths and 4 databases per volume.

-Confirm
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
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.

-DatabaseAvailabilityGroupIpAddresses
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The DatabaseAvailabilityGroupIpAddresses parameter specifies one or more static IP addresses to the DAG when a Mailbox server is added to a DAG. If you omit the DatabaseAvailabilityGroupIpAddresses parameter when creating a DAG, the system attempts to lease one or more IP addresses from a Dynamic Host Configuration Protocol (DHCP) server in your organization to assign to the DAG. You must specify this parameter each time an additional IP address is added to the DAG, such as in the case of multi-subnet DAGs. You must also specify all IP addresses previously assigned to the DAG each time the DatabaseAvailabilityGroupIpAddresses parameter is used. Setting the DatabaseAvailabilityGroupIpAddresses parameter to a value of 0.0.0.0 automatically configures the DAG to use DHCP.

-DiscoverNetworks
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The DiscoverNetworks switch specifies whether to force a rediscovery of the network and network interfaces. You don't need to specify a value with this switch.
By default, internal network heartbeats are sent between DAG members on the same subnet. If there's no response to the heartbeats, network discovery is performed automatically by the system. If you add or remove networks or change DAG network subnets, you can force rediscovery of all DAG networks by using the DiscoverNetworks switch.

Applicable: Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The PreferenceMoveFrequency parameter specifies how frequently the Microsoft Exchange Replication service inspects and automatically rebalances the database copies. If the most preferred database copy (ActivationPreference value of 1) isn't the active copy, the most preferred database copy is activated by performing a lossless switchover.
To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh = hours, mm = minutes and ss = seconds.
The default value is 01:00:00 (1 hour). To disable this feature, specify the value ([System.Threading.Timeout]::InfiniteTimeSpan).
