Assuming that Exchange is already set and in production, it’s often advisable to record its AD integration settings with these commands:

# View current settings by first importing Exchange PowerShell
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn;

# Show static AD server settings of Exchange organization
[PS] C:\Windows\system32>get-adserversettings

The output above indicates that dynamic AD Settings have been set. Most likely, that is preferred so that Exchange organization can adapt to any DC changes in the domain. In the cases where static DC entries must be set, here are some commands to make it so:

# Set Static variables
$dc1="DC1.intra.net"
$dc2="DC2.intra.net"
$exchangeServers=Get-ExchangeServer | select Name

# set the StaticDomainControllers for all Exchange servers
$exchangeServers | %{Set-ExchangeServer -Identity $_.Name -StaticDomainControllers $dc1,$dc2}
# set the StaticGlobalCatalogs for all Exchange servers
$exchangeServers | %{Set-ExchangeServer -Identity $_.Name -StaticGlobalCatalogs $dc1,$dc2}

# Set Exchange AD server settings
$globalCatalog="ADPDC.intra.net"
$preferredDCs="ADPDC.intra.net","AD01.intra.net"
Set-AdServerSettings -ViewEntireForest $true -PreferredGlobalCatalog $globalCatalog -PreferredDomainControllers $preferredDCs
