Fetching mail from Office 365 mailbox using modern authentation?

Hello

I am reading that legacy protocols will be permitted to connect to Office 365 after Oct 13 2020. No more POP, IMAP, EWS, etc.

What are my options, come October, for retrieving email to create tickets?  Presently emails go to a helpdesk mailbox, which is read by ManageEngine to create tickets.

Thanks
