I’m currently experiencing an issue with Exchange 2013 UM. I can’t access to UM user information or activate a new exchange user for UM.
Here’s the Exchange topology:
We’re currently migrating Exchange 2010 to 2013.
Exchange 2013 Details:
– 2 Exchange 2013 FRONT-END
– 2 Exchange 2013 BACK-END
– All are Virtual Machines under Hyper-V 3
– OS Windows Server 2012 (no R2)
– Exchange 2013 SP1 (CU4)
My problem is mainly with the UM part. As a reminder, under Exchange 2013, UM is present on both the FRONTEND (for the routing part UM: UMCallRouter) but also on the BACKEND (UM services).
UMCallRouter services and UMServices are active, respectively on the active FE and BE. Services are running as I have assigned the Exchange 2010 UM DialPlans to the 2013 services: so the service is fully functional on that end.
The problem is when I want to access information from a UM user via the ECP (Exchange Control Panel) I get the following error:
Unified Messaging cannot validate or generate a PIN for UM mailbox ‘Exakis@domain.com': An error occurred while Accessing the user’s mailbox.
Details: Client found response content type of ‘text / html; charset = utf-8 ‘goal expected’ text / xml ‘.
Here is the Error returned by the ECP:
From what I understand, Exchange 2013 relies on the WebServices (EWS) of the back-end for managing security PINs.
We also have several events that I think are related to this problem in the event viewer of the active back-ends:
– ASP.NET 4.0.30319.0 ID : 1309
– MSExchange Common ID : 4999
– MSExchange Web Services ID : 29
So, i’m still searching a solution… L
