In Microsoft Lync 2010, by default, there is no notification for status changes (online, offline, inactive, etc.).
Still, there is a simple solution: Tag for Status Change Alerts
How to do it?
- If we wish to receive notifications for certain contacts just press Ctrl and click on the desired contacts and then right click.
- If we wish to receive notifications for all contacts, just click on the first contacts from the list, press the Shift key and click on the last contact from your list. Then right click on them.
- From the contextual menu choose Tag for Status Change Alerts.
Below are two screenshots for a contact that goes online and then offline.
