In its July 2018 roundup   of Microsoft Teams news, they announced a new feature that I dismissed at first. “Visio in Teams”, I thought. “So what – it’s just read-only with Visio Online.” But this is *not* Visio Online. Or is it?

At the bottom of this article it says, “Viewing diagrams within Teams is free for most Office 365 customers  , but editing is only available for those with a Visio Online Plan 1 or Plan 2 subscription.”

I’ve searched through the articles for ‘co-authoring’, but all it says is “Team members can work together on diagrams through in-app conversations to provide feedback in real time.” But can we edit the same diagram with another member in real time? One article compares the new editing feature to other Office co-authoring capabilities within Word, Excel, and PowerPoint. “We’ve extended these editing capabilities to Visio files, enabling you to make simple changes to your diagrams without leaving the Teams app.

So does this mean we can also co-author as we would in Word? I think not. Oh, but wait…

On one page of Microsoft’s website it says, “Real-time co-authoring – Not available in Visio Online. Advanced reviewer features, such as merge conflicts and compare diagrams, are only available in the Visio desktop application. With Visio Online, you can view, add, or delete comments.”

But on the features page for Visio Online 2 (not Visio Online 1) it says, “Complete diagrams faster with multiple people working on the same diagram at the same time.”

And in order for members to see any changes, they have to refresh the diagram in Teams.

In order to perform with full functionality, we are advised to use the desktop version of Visio. For ‘almost desktop’ functionality, we can subscribe to Visio Online 2.

Update 07/07/2018: Direct from Microsoft: “At this point in time Visio Online does not support co-authoring inside Teams, irrespective of the license. But this is part of our roadmap and we are working to enable this in future.”
