A few considerations apply to using Chatter Messenger:
Chatter Messenger is not available in new orgs created after the Spring ’16 release.
Your administrator can disable Chatter Messenger at the organization level. In addition, you can access Chatter Messenger only if your administrator has selected “API enabled” in your profile permissions. If you don’t see Chatter Messenger when you log in to Salesforce, ask your administrator if they have disabled the feature and granted the necessary permissions to access Chatter Messenger.
Chatter Messenger is not available with Communities. It is available for internal users only when the organization-wide default for the user object is set to Public Read Only.
Chatter Messenger is not supported on Microsoft® Internet Explorer® version 7.0. Internet Explorer 7 users appear offline to other Chatter Messenger users.
