external company telling me i need to allow my users to enter their meetings

does this make sense to anyone?

I have an outside company telling me that they are creating Teams meetings for my company and potential candidates.  She indicates that my company is the only company that is not allowed to start the meetings she creates.  This does not happen to any of her other customers.

She's asked me that I get this fixed on my end.  What am i missing here?  Is there some sort of setting in my tenant that says do not allow my users to start an external teams meeting?
