Get-M365ServiceHealth

<#
.SYNOPSIS
    Reports current Microsoft 365 service health issues and advisories.

.DESCRIPTION
    Pulls active service health issues and message center advisories
    across every Microsoft 365 workload, so incidents affecting your
    tenant get noticed proactively instead of after the help desk
    queue starts filling up with the same complaint from different
    people.

.EXAMPLE
    .\Get-M365ServiceHealth.ps1

.NOTES
    Requires Microsoft.Graph.Devices.ServiceAnnouncement with an active
    Connect-MgGraph session and ServiceHealth.Read.All scope.
