Organizing and accessing contact information in Outlook.com
Hi,
- Open People (the contacts icon) from the app launcher or the left navigation.
- Select All contacts or the contacts list you want to sort.
- Choose Filter or Manage contacts, then select Sort if it’s available.
- Set the sort order to First name or Last name, and choose Ascending (A–Z).
- Alternatively, click the Name column, and it should sort in one click.
I hope this information helps. If you have any more questions, don't hesitate to reach out. Wishing you good luck!
