I went to install the CU5 update today and it fails on the step Mailbox role: transport service.

Error:
The following error was generated when "$error.Clear(); 
          $connectors = Get-ReceiveConnector -Server $RoleFqdnOrName;
          foreach($connector in $connectors) { if($connector.MaxLocalHopCount -gt 1) { Set-ReceiveConnector -Identity $connector.Identity -MaxLocalHopCount 5 } };

When I try to re-run the setup, it fails at the same spot. I can't use the ECP nor the Shell to remove the Receive Connector (it is just a receive connector for the MFP).

Is there any way to remove this receive connector with Powershell not working?

(It looks like this is the problem: http://exchangemaster.wordpress.com/2014/01/24/incorrectly-adding-new-receive-connector-breaks-exchange-2013-transport/ but since I can't get a shell to run in this failed upgrade state I can't take the recommended fix nor just remove the connector.)

I was able to find it -- I had to go one step deeper, specifically

CN=Configuration\CN=Services\CN=Microsoft Exchange\CN=<Organization>\CN=Administrative Groups\CN=Exchange Administrative Group (FYDIBOHF23SPDLT)\CN=Servers\CN=<Server Name>\CN=Protocols\CN=SMTP Receive Connectors

But you set me on the right track.

My first instinct was to delete it but I thought that might cause more problems. So I simply edited the bad receive connector and changed the listening port to something else entirely. I then re-started the update and was able to run through.Everything is good to go now!

So thank you for this.

Hi,

you can see this post: http://exchangeserverpro.com/exchange-server-2013-upgrade-fails-due-to-receive-connector-conflicts/

You must run this command for every "custom" receive connector...

Set-ReceiveConnector
"SERVERNAME\CONNECTORNAME" -TransportRole FrontendTransport

Bye.

Raffa!!!
