Email notification for all users or a group of users when Setting up a future maintenance window
Currently, when a future maintenance window is set up by a SysAdmin, users will only be aware of it if they try to reserve a Sandbox that overlaps with the maintenance.
It would make more sense to also add a system wide or by-group notification email to let you know that a maintenance window will occur in a set time/date.
"CloudShell Maintenance will take place at {DATE} {TIME} {TIMEZONE}"
"System maintenance is scheduled between @StartTime@ and @EndTime@. You will not be able to log in to the system during this time." (same message as the maintenance window message set by the admin").
The admin should be able to toggle on/off whether or not this notification will be sent via email.
Note: This idea was suggested by Quali Partner ADOC International
