We have a Exchange 2010 servers that shows a mismatch of versions with the get-exchangeserver command between the single core and edge server.
The Edge server also shows a decommissioned server.


On the HUB, CAS, Mailbox Server (one server), it shows the Edge has an older build number.
On the Edge Server, it shows both servers to have the correct build number, but it has an old server that was decommissioned properly still as installed.

Both have had Update Rollup 2 for Exchange 2010 Service Pack 3 (KB2866475) installed.
This is confirmed within the Control Panel Installed Updates as well as Help...About in the Management Console.


The layout is:
HUB,CAS & Mailbox Server - EXCHANGE02
Edge Transport Server - EDGETRANS

A server did exist called EXCHANGE01 but that was removed from the network gracefully. It was removed by uninstalling Exchange 2010 via the control panel, and it was removed successfully.
This decommissioned server EXCHANGE01 does not exist in the ADSI Edit under "Configuration, Services, Microsoft Exchange, {DOMAIN}, Administrative Groups, Exchange Admin Group, Servers". Only the existing servers EXCHANGE02 and EDGETRANS are there. No reference to the decommissioned server.

However, when I run the PS command:

Get-ExchangeServer | fl name,edition,admindisplayversion

I get odd results.


On EXCHANGE02

Name                : EXCHANGE02
Edition             : Standard
AdminDisplayVersion : Version 14.3 (Build 123.4) correct build number

Name                : edgetrans
Edition             : Standard
AdminDisplayVersion : Version 14.1 (Build 218.15) wrong build number


On EDGETRANS

Name                : edgetrans
Edition             : Standard
AdminDisplayVersion : Version 14.3 (Build 123.4) correct build number

Name                : EXCHANGE02
Edition             : Standard
AdminDisplayVersion : Version 14.3 (Build 123.4) correct build number

Name                : EXCHANGE01
Edition             : Enterprise
AdminDisplayVersion : Version 14.2 (Build 247.5) decommissioned server


So EXCHANGE02 shows the incorrect build version of EDGETRANS.
And EDGETRANS shows both correct build versions, but has a decommissioned server visible.

How can I fix this up so that this doesn't cause issues and that the next person who comes through these doors doesn't get confused as to what is in the environment?

Thank you
