While most Office 365 subscribers have access to Visio Online, those end users just have file-viewing rights. In addition to outlining those plans, Microsoft's announcement explained that "Visio Online Plan 2 is the new name for Visio Pro for Office 365." Microsoft shows a full comparison of Visio Online Plan 1 and Plan 2 at this page. In a Visio FAQ, Microsoft explained that Visio Online Plan 2 "includes the same capabilities as Visio Professional 2016."

Plan 2 expands on Plan 1 to include the Visio desktop application and the ability to connect Visio diagrams to Office 365 data, priced at $13 per month per user. In a nutshell, Plan 1 permits Visio Online diagram creation and sharing for $5 per month per user, but it lacks the Visio desktop application.

However, specific software use rights for end users depend on selecting between two added options, namely Visio Online Plan 1 or Visio Online Plan 2. Visio Online is included in most Office 365 subscription plans. The news this week apparently is the two added plan options, which are described to a degree in this Wednesday Microsoft announcement. The Visio Online service actually went live in March for Office 365 subscribers. Microsoft describes some of the associated licensing details at this page. It's offered as service via a browser and there also are premises-based Visio applications, namely Visio Standard 2016 and Visio Professional 2016. Visio is an application that lets users map processes in graphical forms of various sorts.

Microsoft this week said it was announcing the "general availability of Visio Online, including two new subscription plans: Visio Online Plan 1 and Visio Online Plan 2," according to a Microsoft spokesperson, via e-mail.
