MS Office/Outlook Presence Integration C# COM Server RRS feed

  • Question

  • I want to implement the Outlook Presence integration for Outlook 2010, 2013 and up.


    I tried to follow the instructions found in the article "Integrating IM applications with Office" ( and implemented the IUCOfficeIntegration Interface in my C# Application. I created an C# Exe that registers the class for COM Interop by basing my code on the official Example How to develop an out-of-process COM component by using Visual C++, Visual C#, or Visual Basic .NET (

    When I run the C# COM Server I am able to instantiate the registered class from another C# Application using the following code:

     Guid clsid = new Guid("394376DD-3BB8-4804-8CCC-9559434004F3");
     Type t = Type.GetTypeFromCLSID(clsid, true);
     object i = Activator.CreateInstance(t);

    When the COM Server does not run I get the Error HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG) as expected.
    I enabled Outlook Presence Logging as described in (, started the C# COM Server set up the registry keys but Outlook is not able to instantiate my COM Class even though the C# Test app can do it. The constructor of the interface class is never called as the log statements are not getting executed.

    In the Outlook Log I get the following error line multiple times:

    hr = 80040154, We couldn't identify the provider type we now try to manually CoCreate using the LCClient CLSID
    I checked the registry keys but they are correct. For some yet unknown reason it does not work. The docs say Outlook would use CoCreateInstance with the CLSID to instantiate the class. I also tried to simply use a C# COM Interop DLL instead of the COM Server but I get the same behaviour there.

    If helpful I can provide the whole program source that implements the interface.

    What do I need to do to make outlook able to find and instantiate my class?

  • Should work with Office 2010 as well as there is a note in the article stating "A handful of Office 2010 applications can integrate similarly with a third-party IM provider application: Outlook 2010, Word 2010, Excel 2010, PowerPoint 2010, and SharePoint Server 2010 (using an ActiveX control). Many of the steps required for integration with Office 2013 apply to Office 2010 as well."

    But we tried with Office 2013 as well and had the same problem.

  • I'm also facing similar issue on OL 2010, OL2013 and OL 2016.

    In my case IUCOfficeIntegration is invoked by Outlook and appropriate methods are called.

    the issue now is, my IMClient is crashing with COMException when I return the IMClient object from IUCOfficeIntegration::GetInterface (IMclient implements ILyncClient, IClient). 

    I don't see enough documentation  in the msdn, if some one have implemented, please share the knowledge.

    I have implemented IMClient as described in

  • HI Krish, 

    Any idea, how do we call back CallbackClass.OnLookup(...) with resultant contact object in IContactManager.lookup() method.
