Exchange: Error you get while you open the EMC / GUI Console:

Error you get while you open the Exchange 2010 EMC / GUI Console:

You also have Exchange PowerShell Error:

And you are unable to access Exchange PowerShell from within the BLUE-Windows_Powershell.

Status:

• Exchange GUI/EMC not opening
• OWA and ECP are running so you can check BRAC permission
• Mail flow is stable and all other services are running
• People have access to Exchange

This was caused by a missing Registry Path entry. I suspect there was a “Service Pack” or “Rollup” installed and not fully

went through (Maybe Missing MSI Sources to other MSP files) and the person did interrupt the setup of the rollup.

Get the Exchange 2010 path from without the \bin\ at the end:

Type path in dos Box

You may also get the path from C:\ExchangeSetupLogs where you see all information.

Regular Path with Exchange on C:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Setup]

“Servcies”=”C:\\Program Files\\Microsoft\\Exchange Server\\V14\\”

This sample customer who has Exchange running on D: drive.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Setup]

“Servcies”=”D:\\Program Files\\Microsoft\\Exchange Server\\V14\\”
