Why upgrade to Microsoft Teams?

Microsoft Teams extends the capabilities of Skype for Business, bringing together chat, meetings, calling, collaboration, app integration, and file storage into a single interface. This new central hub for teamwork can help streamline the way users get things done, improving user satisfaction and accelerating business outcomes. We’re continually expanding Teams’ capabilities to enable you to communicate and collaborate in new ways, break down organizational and geographical barriers, and drive efficiency in process and decision making. Learn more about the benefits of upgrading to Teams in the Forrester report: Total Economic Impact of Microsoft Teams.

When should my organization migrate to Teams?

Skype for Business Online will be retired on July 31, 2021, after which it will no longer be accessible or supported.
