Blocked and Safe Senders lists

Office 365 Blocked and Safe Senders Lists

Office 365 allows users to add senders or domains to their blocked or safe senders lists.  These lists will - regardless of whether a message is marked as Junk or Not Junk by Office 365, force messages to go into your Inbox (for the Safe Senders list) or your Junk folder (for the Blocked Senders list).

A few notes before the actual instructions:

  • The instructions below are for the web version of Office 365.  If you use the desktop version that is part of Microsoft Office, we still recommend using the web version to update your blocked and safe lists.
  • These instructions are for the newer version of Outlook Web Access.  You are using the "Old" Outlook if instead it says "Try the new Outlook" at the top right (If it says this - click "Try the new Outlook" to move to the new version).

 

  1. Open the full Outlook settings by clicking the gear icon at the top right, then choosing "View all Outlook settings" at the bottom.

  2. Click on "Junk email" on the left
  3. You'll be in the Blocked Senders and Safe Senders lists.  You can add a full email address (someaddress@gmail.com) or a full domain (suny.edu for example) a list.

 

Warning: These settings override any rules set by ITS to allow or block external senders - so you should be cautious about adding addresses to these lists.  Even if a message is detected as having fraudulent content - adding a sender to your safe senders list will allow those messages to come through.  Likewise, even if the sender is a legitimate message whitelisted by the college - if you add it to your blocked senders list, it will mark mail from that sender as Junk.
