Acronis Recovery for Exchange Error E007A0001

Hello,

I installed the German Acronis Recovery for Exchange Version 1.0.176.23 Management Console on a new Microsoft Windows Server 2008 Standard 64 Bit Edition German an the Agent on an Exchange Server 2003 with SP2 on Microsoft Windows Server 2003 Standard 32 Bit Edition German with SP2.
I have no receive any errors during the Installation.
If I go on the Management Console I see my Exchange Server with a green hoeing. I would like connect to the listed below Exchange Server and receive the follow error Message "E007A0001 Could not connect to the Server myservername.domain.local".

The hostname and the user credentials are correct.
The User has Domain-Admin rights.
The Service on both server are started without any errors.
I restarted both servers and I deinstalled and installed again the Exchange Agent, but without success.

Please help!

Best Regards
