Without a bandwidth monitoring tool, you have no way to know whether your network speed is on point or whether certain applications are consuming bandwidth like there’s no tomorrow. While doing this manually would take several hours or more, a bandwidth monitor identifies the cause in a matter of minutes. When the specter of poor connectivity rears its ugly head, you can use a bandwidth monitor to search for the root cause. Monitoring network bandwidth is one of the most effective ways to get a glimpse of what’s going on in a network and a reliable way to troubleshoot poor connectivity. You can apply this concept for measuring any SaaS/PaaS traffic as long as you can filter the traffic based on Process Name or Destination IP endpoints, not limited to Office 365.Monitoring your network effectively starts and ends with bandwidth monitoring.

This concept assumes you have pilot batch of users on-boarded to Office 365 or you can monitor a subset of user traffic accessing Office 365 services. This solution uses Azure monitoring, specifically Service Map, dependencies for Service Map like Microsoft Monitoring Agent, Dependency Agent are applicable to this solution.
