SMTP basic authentication connections going away
We have certain apps mailboxes which works on IMAP. We were planning to leverage o365 and migrate those mbxs to Office 365 by enabling IMAP for those mailboxes in office 365.
So, as per Microsoft's plan, would it be a problem for us after the migration?
thetechguru IMAP is a mail access protocol, so you use it to download messages from a mailbox. That will continue to work as Microsoft is developing modern authentication for IMAP (Oauth). I don't know when this will be available, but it is coming. SMTP is used to send messages, so you need to use it in conjunction with IMAP. Make sure that the accounts used by the app mailboxes are enabled for authenticated SMTP connections and stay up to date with developments in this field. And do lots of testing...
