Various DAG maintenance scripts do not work in an Exchange Server 2010 environment

Applies to: Exchange Server 2010 Service Pack 3Exchange Server 2010 EnterpriseExchange Server 2010 Standard


This issue occurs when you deploy Windows Management Framework (WMF) 4.0 in a Microsoft Exchange Server 2010 environment. The following Microsoft Exchange PowerShell scripts for database availability group (DAG) management do not work:
  • StartDagServerMaintenance.ps1
  • StopDagServerMaintenance.ps1
  • RedistributeActiveDatabases.ps1


This issue occurs because of a by design logic in an Exchange Server 2010 environment.

Note Exchange Server 2010 PowerShell scripts, Exchange Server 2010 cmdlets and Exchange Server 2010 setup are not supported in Windows PowerShell 4.0 that is included in WMF 4.0.



Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
