Hi everyone,

Need some help here.  Been trying to install Exchange 2013 to coexist with our live Exchange 2010 environment and was having issues with the mailbox hub transport role.  Been trying to uninstall exchange to try again and come up with the following error.  Any help would be appreciated.  

Error:
The following error was generated when "$error.Clear(); 
                    $agentName = "Text Messaging Delivery Agent";
                    $agent = get-transportagent -Identity:$agentName;
                    if ($agent) {
                    uninstall-transportagent -Identity:$agentName;
                    };
                " was run: "No valid agents.config file was found in 'C:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\Shared\agents.config'.  The default configuration for transport agents can be recovered by running 'scripts\ReinstallDefaultTransportAgents.ps1'.".

Hi,

Run the following two commands and see whether it fix this issue:

cd $exscripts

./ReinstallDefaultTransportAgents.ps1

Thanks,

I Installed exchange 2013 successfully alongside my exchange 2010 with no issues.

I did not make any changes to the setup or move any mailbox roles from exchange 2010 just completed the exchange 2013 install.

My raid controller in the server failed & lost the raid 5 configuration which caused me to have to rebuild my raid array. The raid I rebuilt house all the exchange server folders etc.

As a consequence now my server 2012 OS thinks exchange is installed but it is not. I have tried to run add/remove programs but this fails. I have tried the /m:recoverserver option this fails, I have tried uninstall server from cmd prompt & now get error trying to remove transport role.

I have ran the script as it suggests "reintstallDefaultTransportRoles" but this fails saying it cannot find the Exchange Server Reliant (this is name on my 2013 server).

Any one have any suggestions on how best to fix this install or how to re-install the system?
