If you want to make changes to your settings, such as if you get a new phone number, for instance, you can easily do so in Office 365.
Changing your settings
1. Sign into Office 365 at http://www.lesley.edu/office365. If you are already logged into email or any other Office 365 account, you can still follow these same instructions.
2. Click on your picture (or initials) in the upper right-hand corner and choose My account.
3. You can click on either Security info from the menu on the left, or click on UPDATE INFO > from the Security info box.
4. On the Security info page you can choose to use a different method of signing in (A) or just update an existing number (B).
