Spam Quarantine: Prevent Messages from Going to the Quarantine

Overview

Sometimes the EOP Spam Quarantine will filter legitimate messages. Below are a few actions you or your recipients can take to ensure messages reach the Inbox.

Instructions

To prevent the message from going to the EOP Spam Quarantine, add the sender's address or the domain to your Safe Senders list and report the message to Microsoft as being quarantined falsely when releasing it from quarantine.

Adding a sender or domain to Safe Senders

1. Sign in to Office 365.
2. Choose Outlook.
3. At the top of the page, select Settings (Gear Icon) and select View all Outlook settings near the bottom of the Settings pane.
4. The Settings window will open; choose Junk email.
5. Under Safe Senders and Domains, select +Add and enter the email address or domain that you want to mark as safe in the text box.  Press Enter.
   • To mark a particular domain as safe, such as all addresses that end in utk.edu, enter utk.edu in the text box.
   • To mark a particular person as safe, enter that person's full email address.  For example, to mark all messages from johndoe@utk.edu as safe, enter johndoe@utk.edu in the text box.
6. Select Save at the bottom of the Junk email window to save your changes.

Reporting the Message to Microsoft as Safe

1. Log in to your Spam Quarantine.
2. Select the message from the list of quarantined messages. 
3. Select Release messages. To train the spam filter to not filter these types of messages, leave the check box to Report to Microsoft to improve detection checked. (Note this may take several releases to take effect.)
   
4. At the bottom of the page click Release message.
