Managing personal Outlook.com account settings, security, and privacy
Hi Nicole Nantel,
Welcome to Microsoft Q&A forum.
Please note that our forum is a public platform, and we will modify your question to hide your personal information in the description. Kindly ensure that you hide any personal or organizational information the next time you post an error or other details to protect personal data.
The domain you see in the From line may not always be the real sending address, as some senders can spoof or disguise the visible sender information. Because of that, blocking only the domain shown in the message list may not reliably stop all similar emails.
Please open one of the unwanted emails in Outlook.com and check the message headers to identify the actual sender address or domain. You can follow Microsoft’s guide here: View internet message headers in Outlook. Microsoft notes that checking the header can help confirm whether the sender address is different from what appears in the message.
Once you identify the actual sender address or domain from the header, please block that exact address or domain in Outlook.com:
- Go to Settings > Mail > Junk email.
- Under Blocked senders and domains, add the exact email address or domain you found in the message header.
- Select Add, then Save.
If the emails continue, you can also create an inbox rule in Outlook.com using conditions such as sender address includes or specific words in the message header, then choose to move or delete those messages automatically.
Please feel free to let me know if you have any further updates, thanks.
