Note - Microsoft have now deprecated the ability to connect to IMAP services using PLAIN authentication.

Microsoft and Google are changing the connection requirements for third-party applications (like Incisive) to send emails through their SMTP (out-going) email services.  These connections now require a token to be requested and passed back to Incisive application, instead of just requiring your encrypted login & password, for the Microsoft & Google services to allow the email to go through.

There is a alternative security option called 'App Password' which may work for you, but is only available if you have 2FA authentication enabled on your Microsoft account.

Microsoft have a Knowledgebase article on adding App Passwords

The basic steps are:

  1. Login to your Microsoft account

  2. Add a new App Password in the Security Info section

  3. The App Password is then automatically generated.  Copy & save the password as you won't be able to view it again.

  4. Use the password for the SMTP Authentication field in Setup > Provider > Email
