Issues with using Copilot on Outlook Calendars

Seems that Copilot cannot decipher calendars very well.  I have tried several times to automate some work on Outlook Calendars and Copilot is completely lost when it comes to working with calendars.  One example was when I tried to move 3 attendees from meetings I had scheduled out for several months from required to optional.  It told me it did not have meetings with these 3 people in attendance but showed me events with these 3 people in attendance and asked if I wanted to look at these events!!! Also one other recent instance was to take a Group Calendar and just list out the daily events for the next several months.  It seems like it is unable to work with calendars in Groups?
