Configuring preferences and options in Outlook.com
For Outlook on the web, profile editing is not done from Outlook for iOS, and some profile details are edited from the My account or My profile area instead of a general Settings page.
Try these paths:
- In Outlook on the Web (OWA), select the profile image.
- Open My profile.
- Select Update profile.
If the goal is specifically to change phone numbers in Outlook Web App:
- Go to the My account page.
- In Contact numbers, add or edit work, fax, home, and mobile numbers.
If the profile option still does not appear where expected, use Outlook for Windows:
- Open Outlook for Windows.
- Go to File > Office Account > User information > About me.
- This opens the Microsoft 365 profile online, where Update Profile is available.
