Some of the instant messaging features shared between your instant messaging (IM) client and Microsoft Outlook may be missing. For example, in Microsoft Outlook 2010 the Quick Contacts from Microsoft Lync are not available in the Outlook To-Do Bar, or presence information and contact photos do not appear in Outlook.
This problem can occur when a wrong or incompatible IM client is listed as the value for DefaultIMApp in the registry.
In one case, Microsoft Support teams have seen the problem described in the "Symptoms" section when the value of DefaultIMApp was set to "Cisco Jabber". Cisco Jabber is manufactured by Cisco Systems.
