Hi Readers,

Some of the users reported that their Communicator/Lync  Presence in outlook stopped working.

On further analysis  it is found that users have installed another IM client (Cisco Jabber) for testing purposes.

There is a registry key that gets set when another IM client is installed.

HKEY_CURRENT_USER\Software\IM Providers

DefaultIMApp: 

We have uninstalled the Jabber client & then reset the reg-key back to  Communicator as shown below to fix the issue.

restart both outlook & communicator in the end.

Regards
