Hi,
Thank you for reaching out. Microsoft has removed the traditional Junk Email controls in the New Outlook interface, including the Junk Email option under Settings > Mail, the right-click "Junk" menu, and the "J" keyboard shortcut.
Even though the New Outlook doesn’t show traditional Junk Email options, you can still try this workaround to unblock a sender using Outlook on the web.
- Go to https://outlook.office.com.
- Click the gear icon for Settings.
- Select Mail.
- Open Junk Email.
- Remove the sender from your Blocked Senders and Domains list so their emails start coming through again.
Hope these helps and let me know if you need further assistance.
