Set-CalendarNotification

Exchange Online ExchangeOnlineManagement Set-*

The Set-CalendarNotification cmdlet allows users to set text message notification options for calendar events in their own calendar. By default, the MyTextMessaging end-user role gives access to this cmdlet, so admins can't configure text messaging notification for calendar events in user calendars. **Note**: This cmdlet is deprecated in Exchange Online PowerShell. The text message notification service is discontinued in Microsoft 365.
