Hi everybody,

I have a problem on installing a dedicated Exchange UM server.

The customer already have a Exchange Hub on other physical server.

The UM is connected with Lync server with an internal cetificate on a internal root authorities (private pki).

--> I can let a message, it's working.

But nothing goes on Exchange Hub.

I have check all the solutions like it but nothing works: http://eightwone.com/2011/01/07/exchange-um-voicemail-and-missed-call-delivery-failure/

So, I think it's linked with my UM certificate. But on Hub, there is a public certificate on smtp service. If I put it on my UM, Lync voice don't work, and vis versa. I haven't found problematic event on certifiate, logs are empty, so it's a mystery...

If anyone has a solution, it will be nice because I'm blocked...

Thanks

Marc
