Turn Junk Mail Filtering Off/On
Turning your Junk Mail filter to be off or on should be done through the Exchange Online interface: https://outlook.office365.com/ This setting in Exchange Online will override any setting for junk mail filtering that you may have set up through your local mail client.
- Log in to https://outlook.office365.com/
- Click on the Gear icon at the top right of the web interface, near your name.
- Scroll to the bottom of this list, and under 'Your App Settings', click on Mail.
- The Mail settings will appear on the left hand side of the window. Under Mail > Accounts, click on Block or Allow.
- At the top of this section, to turn OFF junk filtering, select: Don't move email to my Junk Email folder. To turn ON junk filtering, select: Automatically filter junk email.
If you turn junk filtering off, but still have addresses under Blocked Senders, emails from those addresses will still be moved to your Junk folder.
