Microsoft 365 Administrator — Question 327

You have a Microsoft 365 E5 subscription that contains the following user:

Name: User1 -

UPN:[email protected]-
Email address:[email protected]

MFA enrollment status: Disabled -
When User1 attempts to sign in to Outlook on the web by using the[email protected]email address, the user cannot sign in.
You need to ensure that User1 can sign in to Outlook on the web by using[email protected].
What should you do?

Answer options

• A. Assign an MFA registration policy to User1.
• B. Reset the password of User1.
• C. Add an alternate email address for User1.
• D. Modify the UPN of User1.

Correct answer: D

Explanation

The correct action is to modify the UPN of User1, as it needs to match the email address being used to sign in. The other options do not address the core issue of the UPN not aligning with the email address, which is essential for successful authentication.
