By default outlook 2007 shows presence from Microsoft Office communicator. We have our own communicator running along with Outlook on same machine instead of Microsoft Office communicator. I want to show presence information using custom IM application but don;t know where to start.
I just got following so far. My application is .Net. From following note I am assuming I have to expose COM and register for TreatAs and implement Windows messanger API but don;t know which function in API should I implement to show presence.If there is sample for this then it will be most useful.
- Uninstall Office Communicator if it is installed.
- Use TreatAs (COM) to replace the Office Communicator CLSID (class identifier) with third-party CLSID. The CSLIDs for Office Communicator is {8885370D-B33E-44B7-875D-28E403CF9270}. For more information about TreatAs, go to http://msdn2.microsoft.com/en-us/library/ms679737.aspx.
- Implement the Windows Messenger API. For more information, go to http://msdn2.microsoft.com/en-us/library/ms630961.aspx.
- Set the IM Application process name in the registry value REG_SZ under HKLM\Software\Microsoft\Office\Outlook\Call Integration\IMApplication = <app_process_name>. For example: HKLM\Software\Microsoft\Office\Outlook\Call Integration\IMApplication = MyIMApplication.exe.
5. Set the IM provider that Office applications call to be Office Communicator by configuring the following registry value: REG_DWORD HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\PersonaMenu\RTCApplication.
Note: Use value 3 for Office Communicator.
6. Advertise the start and shut down of your application’s COM server by setting the registry value REG_DW HKEY_CURRENT_USER\Software\IM Providers\Communicator\UpAndRunning. The possible values to set: 0 (not running), 1(starting), and 2 (running).
