Configuring preferences and options in Outlook.com
Hello, thank you for reaching out.
Could you please check whether you experience the same issue when using a private browsing tab (Incognito session) or another browser?
- Open an Incognito tab in any web browser, then copy and paste the link below: https://outlook.live.com/mail/0/options/mail/junkEmail
- In the Blocked senders and domains section, delete the email address you blocked, then click Save.
- Next, go to the Safe senders and domains section, add the email address to your safe senders list, then click Save.
If you receive an error, try using another web browser and check whether you can make these changes to your Outlook email account.
