We've developed a tool to find basic authentication devices/users ► [ Ссылка ]
These legacy clients will stop working coming October 1st and need to be migrated to Modern Authentication: [ Ссылка ]
This tool helps tenant admins finding all users still using basic authentication connecting to Exchange/Microsoft 365.
Due to security flaws Microsoft is enforcing this end of support for protocols like IMAP, Exchange ActiveSync (iPhone), POP3 and others, which means a lot of users might be affected if they don't start using OAtuh (Modern Authentication).
Give the tool a try and find users which will need support to move to Modern Authentication.
