How to whitelist in Outlook.com (updated for 2021)

Add an email address to your Outlook contact list or safe sender list

Outlook.com is now the home for Hotmail, Live Mail, and other Microsoft email products for consumers. If you’re finding email you want is ending up in your junk mail folder, there’s a couple things you can do to prevent that from happening in the future. First, if the email is already in your junk folder, you can mark it as not spam to teach Outllok that you want to receive that type of message in the future. If you want to prevent desired messages from ending up in junk before they get there, you can use the safe sender list to designate specific sender’s email address, or whole domains, as “safe”. Email addresses in the Safe Senders List are never treated as junk email. We’ll outline the detailed steps for doing these things below.

Safe Senders list

By default, email addresses in your Outlook contacts are considered safe senders by the Junk Email Filter, but you can change this setting. Email messages from safe senders are never routed to the Junk E-mail folder.

Add a sender to the Online (web) version of Outlook

To add people to your Safe Senders List, do the following:

  1. Sign into your Outlook.com account from a computer
  2. Select the Settings icon (gear icon) at the top-right corner
    Outlook settings icon
  3. Select View all Outlook settings

  4. Select Mail
  5. Select Junk email
  6. Under the Safe senders and domains header, select Add

  7. Enter the sender email address then press the [Enter] key on your keyboard
  8. Select the Save that appears in the bottom-right corner

Now messages sent from that safe email address will end up in your inbox going forward.

Check blocked senders and safe senders list

If messages keep ending up in your junk folder from a safe sender, you may have accidently added that sender to your blocked senders. You can check that list to make sure it’s correct.

  1. Sign into your Outlook.com email account
  2. Select the Settings icon (gear icon) at the top-right corner
  3. Select View all Outlook settings at the bottom
  4. Select Mail, and then select Junk email
  5. If you see the sender’s email address listed under the Blocked senders and domains header, select Remove button (trash can) next to it to remove it from the list

Mark a message as “not junk”

If a desired message is already in your junk folder, you can mark it as not spam. This will move the message to your inbox and teach Outlook that you trust that type of message. You should also regularly check your junk folder to see if legitimate messages ended up there that you didn’t notice. Messages in the junk mail folder are automatically deleted after 10 days.

  1. Sign in to your Outlook.com (Live) account
  2. Select the Junk Email folder and look for the missing email
  3. Right-click the desired email and then select Mark as not junk. The message will automatically be moved to your inbox.

I can get to the Mail / Junk Mail / Safe Senders and Domains list, but it will not allow me to enter a domain. Anything that starts with the @ symbol is not accepted. I get the message “Error – Either the email address or the domain name isn’t formatted correctly” If I try entering the domain without the @ key, it does not make it to the list. There appears to be no way to enter a safe domain for Outlook.

this sucks. It fails on step 2. I would think if your entire site is for whitelisting you could get it right. Probably as much to do with Microsoft’s lousy difficult obtuse procedures, but you could do a better job.

I’ve followed these steps consistently for months and yet the emails are still going into my junk mail. Is this an issue
