Ondemand Monitoring will check if your user can sign in, send, and read emails with Outlook on the web. Ondemand Monitoring uses synthetic monitoring to simulate the user condition. It logs in to a monitoring mailbox that is located in the same mailbox database as the mailbox having issues. It then sends an email to a monitoring mailbox in a different location within the O365 service and delivers the email back to the monitoring mailbox in the user's mailbox database location. The results of the test allow you to see whether the monitoring mailbox is having the same issues as your selected user.
