Outlook sync: Method 'TestConnection' is invalid

sphinx

Hi,

I'm trying to setup a sync between Outlook 2010 and RTC 2009R2 via web service. My webservice is running (see attachment) and everything on NAV side is setup as it should be (walktrough MSDN). But when i press Test Connection in the outlook Addin (settings), then it returns the error:

The connection to "" Microsoft Dynamics NAV database failed. The program returned the following error: connection error: Method "TestConnection" is invalid! connection string:
NavsynchronizationUrl="http://localhost:7047/DynamicsNAV/WS/Codeunit/DynamicsNAVsynchOutlook;CompanyName=XXX;

Please verify your synchronization settings. If the problem persists contact your system administrator.




Someone has experience with this?

Best regards
