Hello,

We tried to update a Exchange 2013 server to CU8 because we needed support from Microsoft (certificate revoked, so OWA not working anymore) and they could only help us after updating to CU8 first. The problem is that the update got stuck and now Exchange is not working at all anymore. Since it is a production enviroment and there is mail in all outboxes we do not want to turn back to a snapshot but solve the problem and continue the update. Any help is welcome because all mail is down now :-(

The error we received at the Exchange Server is:

Hello Gadget,

Please find the solution as follows

This error is concern about WMSVC certificate which was deleted, we could refer to the following steps:

1- Go to IIS Manager and select server certificate,

2- Select Create Self-Signed Certificate,

3- For Server 2012 in the Friendly Name Field type: WMSVC and select the personal (certificate Store),

4- Now go to Management Service,

5- From SSL Certificate choose the newly create WMSVC Self-Signed Certificate,

6- Apply,

7- Now  start service of Web Management service.

Look like there a problem with receive connector binding, each receive connector need to have unique IP:Port:RemoteIPRange binding.

Usually you can't enable 2 Receive Conenctors that overlap on those parameters, but there seem to be a problem with disabled receive connector being analyzed during CU8 setup.

Did you have disabled receive connectors prior to the upgrade?

Hello Bruce, the engineer from Microsoft has indeed removed connectors so after that the update to CU8 worked. The problem now is that the engineer is done working and we only have internal mail and outgoing email. The external mail is not coming in yet. We cannot check or change the connector yet since the owa/ecp is not working yet. Do you have any idea how to test or make the incoming mailconnector working?
