Managing personal Outlook.com account settings, security, and privacy
Hi Chakan Glou,
Welcome to Microsoft Q&A forum.
For the standard steps (updating the account display name, removing the unwanted suggestion via the X in the To field, and checking whether the entry is saved in People/Contacts), you can refer to the guidance provided by Q&A Assist.
In addition, to help prevent the suggestion from returning, please also try:
1. Clear / turn off expanded “Suggested people”
- Settings > General > Privacy and data
- Under Suggested people, select Clear data and turn off.
2. Mailbox setting review
- In Outlook on the web: Settings > Mail > Rules and Forwarding: remove anything you didn’t create and confirm forwarding is not enabled.
- Review connected apps and remove access for anything unrecognized.
Please feel free to let me know if you have any further updates, thanks.
