Dynamics 365 includes a basic diagnostic tool that analyzes the client-to-organization connectivity and produces a report. To run the Dynamics 365 Diagnostics tool, follow these steps.

• On the user’s computer or device, start a web browser, and sign in to a Dynamics 365 organization.
• Enter the following URL, https://myorg.crm.dynamics.com/tools/diagnostics/diag.aspx, where myorg.crm.dynamics.com is the URL of your Dynamics 365 (online) organization.
• Click Run.

The report displays a table with test and benchmark information. Of particular importance is the Latency Test row value. This value is an average of twenty individual test runs. Generally, the lower the number, the better the performance of the client. Although users may receive a satisfactory experience by using connections with more latency, for best application performance we recommend that the value be 150 ms (milliseconds) or less.
