Zoom Appts, when sending in Outlook will not give option to use certain email accounts

[Bing240x]

I have 6+ different email accounts in Outlook, at least 4 of which need to be the senders of Outlook/Zoom appointments. However, when i create the Zoom meeting and go to email it to the invitees I click the drop down box for :FROM: and i only get 2 email options.

How do i get my other email addresses recognized as senders?

As it is, i have to email the Zoom appt to one of the unrecognized accounts, delete the portion of the email that shows the wrong signature from the 2 accounts i can send from and re-forward the appointment from the proper email account to the desired participants.
