Scheduling Zoom Meetings for others from Outlook, they all have given me privilege's

I am the scheduler for our office, and have been given privilege's by all of out team members to schedule for them.  I schedule the meeting from their Outlook calendar, the meeting appears it says,

Hi there,

(the correct team member) is inviting you to a scheduled zoom meeting.  Etc.

When they go into the meeting and try to start the meeting it says the host must start the meeting.  What am I doing wrong?
