e-mail is slow to deliver. Even in Webmail. If this was just outlook connectivity issues then i'd expect to see the e-mail in webmail but there's definitely a delivery or routing issue. My colleagues receive the same e-mail on time & I would not. Very intemittent as well— Stuart Graham (@stueyg25) June 21, 2022
According to the notification in the admin center, this is limited to Europe— Raphi (@RaphiRou) June 21, 2022

The Importance of Office 365 Monitoring
In a cloud-world, outages are bound to happen. While Microsoft is responsible for restoring service during outages, IT needs to take ownership of their environment and user experience. It is crucial to have greater visibility into business impacts during a service outage the moment it happens.
ENow’s Office 365 Monitoring and Reporting solution enables IT Pros to pinpoint the exact services effected and root cause of the issues an organization is experiencing during a service outage by providing:
- The ability to monitor networks and entire environments in one place with ENow’s OneLook dashboard which makes identifying a problem fast and easy without having to scramble through Twitter and the Service Health Dashboard looking for answers.
- A full picture of all services and subset of services affected during an outage with ENow’s remote probes which covers several Office 365 apps and other cloud-based collaboration services.
