Sending, receiving, and organizing email in Outlook.com
Hello derp
From your description, I understand that you accidentally blocked your sender.
You can unblock an accidentally blocked sender in Outlook on the web by following these steps:
- Sign in to Outlook.com via your browser
- Click the "Settings" gear icon in the top right corner.
- Navigate to "Mail" > "Junk email".
- Under the "Blocked senders and domains" list, look for the address you accidentally added, click the "Trash can (Delete)" icon next to it to remove it from the block list, and then click "Save".
For more details, you can see: Block or unblock senders in Outlook
