Configure presence in Skype for Business Online
By default, anyone who can communicate with one of the people in your organization using Skype for Business can also see whether that person is online. Skype for Business shows whether a person is available online, in a meeting, offline, or another indicator.
As the admin for everyone in your business, you can choose who sees their online presence in Skype for Business.
Go to Office 365 admin center > Admin centers > Skype for Business.
In the Skype for Business admin center, choose organization.
Under presence privacy mode, select one of the following settings, and then choose Save.
|Setting||Who can view a user's presence|

|Display presence information only to a user's contacts
||Anyone in a person's Contacts list who they have not added to their External or Blocked list.
Individuals can override your default settings in their Skype for Business app: Settings > Tools > Options.
