Now that Microsoft Visio 2016 is firmly into rapid updates, especially with Visio Pro for Office365, I thought it would be useful to update a diagram of mine that shows the Microsoft Support Lifecycle for Visio. All of the data comes from the following web page : https://support.microsoft.com/en-gb/lifecycle/search/default.aspx?alpha=visio%20&filter=filterno
The diagram clearly shows that we are already past the date of mainstream support for Visio 2010, and are well into its extended support period.
There is no official support from Microsoft for Visio versions prior to 2007.
