How to: Whitelist Email Addresses in Microsoft Office 365

Sometimes Exchange can be a little overzealous in protecting you from spam and other unwanted email. To make sure messages get through, you can whitelist email addresses in Office 365.

Whether you’re new in the IT Environment or an IT Pro getting started managing Office 365 Admin center, here are a few tips on how to do white list an email address or domain in Exchange Online or Office 365. Believe me, it is pretty easy to do.

Well, let’s get started:

1. Sign into Office 365 by going to https://portal.office.com and sign in.

2. Click on Admin from your list of apps.

3. In the left-hand column, click on Show all and then click Exchange to open the Exchange Admin Center.

4. Click on Protection from the left-hand menu.

5. Click on Spam Filter.

6. Double-click on Default.

7. In the pop-up window, click on Allow Lists.

8. Under Allowed Sender or Allowed Domain, click the + to add a new email address. Be careful about allowing whole domains, as entering popular domains here like gmail.com, outlook.com, hotmail.com, etc. can allow bad actors to bypass filtering.

9. In the window that pops up, add the address you’d like to let through.

10. Click Ok and then Save.

That’s it! Now email from the addresses you white listed will be delivered to your organization’s inboxes, not marked as junk anymore.
