I have un open case number: 7109296761

My Outlook.com primary calendar has unexpectedly changed to an empty calendar named “Calendar1”. My original calendar named “Calendario” still contains all my appointments. Calendar1 cannot be removed or renamed. Classic Outlook confirms that GetDefaultFolder(olFolderCalendar) points to \\******@hotmail.com\Calendar1. The To-Do Bar is therefore empty. Please restore “Calendario” as the primary/default calendar folder without moving or deleting its contents.
