This article applies to Microsoft Dynamics AX for all regions.
Assume that you do not have permission to access the Application Object Server (AOS) that is defined by the default Microsoft Dynamics AX configuration that uses the Excel add-in in Microsoft Dynamics AX 2012. In this situation, if the default Microsoft Dynamics AX configuration is incorrect, you receive an error message that resembles the following:
Unable to connect to a Microsoft Dynamics AX WCF Service.However, you cannot open the Options dialog box to change connection information about the Excel Add-in workbook.
This problem occurs because the Client SDK does not obtain a default WCF configuration to work with. The add-in uses this default WCF configuration and just overrides the endpoint URIs to switch between AOSes.
