We’re excited to announce a new preview release of the Microsoft 365 network connectivity test tool at https://connectivity.office.com today.

This update builds on the existing features (network connection map, 20+ network connectivity tests) and adds a connection to your Microsoft 365 tenant so you can submit your test report to your administrator in the Microsoft 365 Admin Center. The update also features a new, streamlined user interface and updated documentation.

The tool shows elements detected from your network perimeter in a map:

We are maintaining all the existing tests we currently run:

Network backhaul distance from the user to the network egress
In use Exchange Online service front door
Comparative performance of Microsoft 365 customers near you
Time to make a DNS request on your network
Distance to your DNS recursive resolver
Distance to y our proxy server if one is detected
Your VPN if one is detected and evaluation of whether you are following split tunnel guidance
Exchange Online service front door network latency
Best Exchange Online service front doors for your location
The in-use Exchange Online DNS entry
SharePoint Online service front door latency
SharePoint and OneDrive download speed
Buffer bloat while under download load

NEW: Connection to your Microsoft 365 tenant and ability to submit test reports to the Microsoft 365 Admin Center.

You do not need to sign in to run the tests and see results, but if you sign in you are then able to share test reports with your administrators, your account team at Microsoft, your coworkers, and with anyone using a deep link URL. Sharing with coworkers and with a deep link URL are controlled by the tenant administrator.

By default, the deep link URL sharing is disabled in connectivity.office.com but an Administrator can enable it.

Coworker sharing is enabled by default for connectivity.office.com but can be disabled by an administrator. Once you have shared the report, send the other user(s) a link to https://connectivity.office.com/reports and ask them to sign-in.

You can review test reports that you previously ran while signed in by selecting the Reports node.

There is also a page showing the status of Microsoft’s global network and any issues impacting Microsoft 365.

Tenant administrators with the Report Reader role can view the network test reports under Health -> Network Connectivity (preview).
