Outlook.com shared calendar disappeared for one user
I have a personal Microsoft account with a Live.com address. For over 10 years, I have had a calendar that is shared with my wife and daughter. It was created when Microsoft introduced the Family Room feature, which created a shared OneNote and shared calendar. While the Family Room feature was discontinued, the shared OneNote and shared calendar have continued to work without problem until today. The shared calendar has disappeared from my daughter's Outlook on Windows, Web and Android. My wife still has access to the shared calendar. I have tried removing her shared access permission and then adding it again. She receives the invitation to accept the access and clicks Accept. The shared calendar reappears in her Outlook calendars with all events shown, but after a few seconds, the calendar disappears. I have not found any useful information about this problem online. All the articles I can find relating to problems with shared calendars relate to Outlook for Microsoft 365 and not the consumer Outlook.com. If anyone can help resolve this problem, it would be greatly appreciated.
