Unable to setup O365 Account

[NateC]

Hello!

I am trying to setup my work O365 email, but I am receiving errors for both IMAP and POP3.

IMAP

POP3
New Users can only post 1 media/ post, but the error reads: "Setup could not finish - Username or password incorrect. (POP3 SASL auth PLAIN authentication failed: -ERR Authentication failure: unknown user name or bad password.)

It is saying username or password is incorrect, but I verified multiple times that the username and password is correct by signing in successfully through office. com and even resetting the password and using the new one.

Settings I’m using:

IMAP - Using outlook.office365.com for the server, port 993, SSL/TLS

POP3 - Using outlook.office365.com for the server, port 995, SSL/TLS

Any guidance is appreciated!

Depending on the configuration the administrator may also have to specifically allow the app “K-9 Mail” to be used to access your account. In the “Set up a new account” screen enter your email address. Tap the “Manual setup” button. Tap the “IMAP” button. Enter outlo…
