Overview

Follow these steps if you are having trouble signing into Outlook with your Microsoft 365 account.

Step 1 - Start with the onmicrosoft.com Address

First, try signing in using the @myorg.onmicrosoft.com format email address
Example: joe@myorg.onmicrosoft.com
Use the same password as your normal email account

NOTE: This sign-in attempt will fail — this is expected and part of the process.

Step 2 - Fresh Authentication Session

This failed attempt will open a fresh authentication session inside the Outlook app, which is required for the next step to work correctly.

Step 3 - Sign In with Your Correct Credentials

Outlook will now prompt you to sign in again
This time, enter your correct email address in the standard format
Example: joe@mydomain.com
Enter your normal email password

Outlook will now redirect and complete the sign-in process without issues.

Notes

This method works by forcing Outlook to reset its authentication session before accepting your correct credentials
If the issue persists after following these steps, contact Twilight I.T. for further assistance
