About availability and presence status
The desktop app automatically detects and displays a user’s availability status as one of up to seven states: online, away, busy, offline, in-call, in a meeting (if Outlook integration is enabled), or pending presence subscription approval. You can also manually set your status by clicking on your availability flag.
To view presence information, a contact must authorize the presence relationship. If a contact accepts a presence subscription, his or her presence will be shown automatically.
Automated location detection is supported as part of presence. You can choose to disable it in Preferences or via a separate pop-up dialog.
