Boss cannot start a zoom meeting that I set up, it says I am the host.

I set up zoom meetings for my boss as a delegate via outlook and I list myself as the alternative host when I set up each meeting. I will get a phone call at the time of the meeting saying that he cannot start the zoom meeting and the message he gets is I am the host.   When you open up the invite in Outlook, it clearly says  Boss Name is inviting you to a scheduled meeting.     This has been happening for a while now but it is very random.   When it happens I notify our IT department and they perform an update.  Has this happened to anyone else, if so, did you find a resolution? Thank you!
