Copilot does not create an appointment in the calendar even though it claims to do so.

I have a new calendar in Outlook.

I tell Copilot to create a new entry in this calendar with the title X and the time 4.11. 1 p.m.

Copilot replies that it has created this appointment—even with a reminder.

But the appointment never appears in the calendar.

What am I doing wrong? What else do I need to configure so that Copilot creates an appointment for me via chat in a named calendar?
