When you open a message in Microsoft Outlook, or when it is displayed in the
Reading Pane, the online status

of a person is shown beside the sender's name. In addition, if you enabled this option, each name on the
To and
Cc lines will display the online status when you rest the pointer on the name.
- On the Tools menu, click Options, and then click the Other tab.
- Under Person Names, select the Display online status next to a person name check box.
- Optionally, select the Display online status in the To and Cc fields only when mouse pointer rests on a person name check box. Note:This option allows you to still see online status information, but only when you rest the pointer on a name.
