Yammer

Yammer is a collaboration tool and social network that helps you connect and engage across your organization. It is closed, that is, only those who have access within an organization, school or institution can join and see what you are posting.

Yammer provides Microsoft 365, and is suitable for iOS and Andragog, as well as Internet browsers. A Microsoft account is required to sign in. From Yammer you can easily access Outlook, Word, PowerPoint, and several other applications that are part of the Office suite.
