Steps to invite bulk number of Guest to your meeting and event on MS Teams using outlook

Looking for an option to be able to invite over 1000 people to a MS Teams Live meeting. Currently outlook marks spam if over 500 people. Need a simple way for invitees to receive an invite with a link to the event and add it to their outlook calendar. Any help greatly appreciated - nothing found thus far....mijawidnazir
