A very common question in forums I participate.
Exchange 2000/2003:Â Follow these steps
- Start the Microsoft Exchange Administrator program.
- In left pane | Expand objects | Locate server object.
- Right-click server object | click Properties.
Exchange 2007: Use Powershell cmdlet Get-ExchangeServer to achieve the same.
Get-ExchangeServer | fl Name, Edition, AdminDisplayVersion
Good you are done !!!!!
