Hi Andrew
Are you facing issues in outlook?
If Yes, then you can resolve the issue by using the app password
If you enabled the MFA then you have to configure the app password which is under the Security info
Refer to this link to create an app password.

After creating the password you can use this password for configuring the email module without any error.
I hope it helps
