I get error message below when I try to connect Microsoft Project 2016 to my Visual Studio Team Services (VSTS/VSO) project.

TF80070: Team Foundation encountered an error while performing the operation...


  • Create a new project file & save it
  • Team > Choose Team Project
  • Select my server
  • Select my collection from the list
  • Select my team project
  • Click Connect

Please can you help me track the problem down?

Note: I am able to connect Excel to a VSTS query and retrieve results, so I believe this not to be a connectivity issue.

Installing the Team Foundation Server Standalone Office Integration 2015 (free) solved this problem for me.
