Sending Bulk Meeting Invites

Good morning Zoom Support,

What is the best way to send out bulk zoom meeting invites?  Currently, when I send out large amounts of emails (re: 80+ invites) I am being blocked by Microsoft 365 and have to call IT support to get unblocked.  Is there a way to have Zoom send these email invites rather than have them come from me?  What are the best practices?

Thanks, and have a good day!
