Skype for Business will be released in three stages leading to the public launch of the app during the third quarter of 2016. Starting today, Skype for Business Mac users will be able to see meetings in the Skype business client through built-in Outlook calendar integration, joining them with a click. Full screen video, content viewing, in-meeting chat, and the ability to invite additional people to the meeting are all supported features.
In the second phase of the Public Preview, Microsoft plans to add instant messaging, presence, and contacts, which will come in the early summer. Phase three, which will include telephony features, will be available later in the summer.
Skype for Business, designed for corporate users, supports up to 250 people per call and it includes enterprise-grade security features and employee account management.
Microsoft's commercial customers can request an invite to test the Skype for Business Mac Public Preview through the Skype for Business website. Microsoft plans to begin issuing invites to IT administrators to download the client with a gradual expansion of the preview coming in the current weeks.
