In July 2021 the Visio Web App was made available for users with Microsoft 365 Business Basic/Standard/Premium, Office 365 E1/E3/E5/F3, Microsoft 365 F3/E3/E5, and Microsoft 365 Apps for business/enterprise licenses.

Now there's a new Visio app for Teams available for users to view, edit and create Visio files without leaving Teams. If a user is licensed with Visio Plan 1/Plan 2 then it’s functionality available to them in the Teams app, otherwise it's the Visio Web App (aka Visio in Microsoft 365) functionality for those users licensed with the Office/Microsoft 365 licenses listed above.

The Visio app comes pre-installed for enterprise users and can be accessed in several places from within Teams, for instance, in the left pane by selecting More added apps (). Scroll through the list of available apps and then, select the Visio icon to open the app within Teams.

Note: The Visio app is not yet available in the new Teams experience but is coming soon.
