This proof of concept tool evaluates the quality of your network connection to Microsoft 365 services, like Exchange, SharePoint and Teams.

To troubleshoot network connection issues for someone in your organization, send this page to them and have them run the test for their location.

Your network connection to Microsoft 365 depends on several things – your internet service provider (ISP), how close you are to an entry point for Microsoft’s global network and an Office 365 service front door server, and how close you are to the point where your organization or home network connects to your ISP. This tool tests these factors and provides recommendations to improve your connectivity. Learn more
