Self-Service: Release Messages from Quarantine
Spam filtering in Office 365 is configured to quarantine e-mail considered to be "high confidence spam" - i.e. e-mail that receives a score of 9 out 9 in Exchange Online Protection. Users can view and release quarantined e-mail using the the self-service option available in Office 365 and documented below.
Access Office 365 Quarantine and Release Quarantined Messages
- Log in to https://security.office.com/quarantine using your eID in the format of "ename@colostate.edu" along with your eID password.
- Find and select the message you want to release from quarantine.
- Click on the envelope icon to release the message.
- Click "Yes" on the warning message asking you to confirm that you want to release the message.
- Do not close the window until you receive confirmation.
- The previously-quarantined message should arrive in your Inbox.
Manage Safe and Blocked Senders
Optionally, users may want to add a sender or sender domain to their Safe Senders list in Office 365 to ensure e-mails from the sender are not quarantined. Steps to add Safe Senders are provided below.
- Log in to the O365 Portal at https://portal.office.com. Enter your username as "ename@colostate.edu" when logging in.
- Access the "Outlook" section of the portal by clicking the "waffle" icon in the upper left corner and clicking the "Outlook" tile.
- Click the "Gear" icon in the upper-right and then click the "View all Outlook settings" link (towards the bottom).
- On the left, click "Mail" > "Junk email".
- Use the resulting form to set Blocked senders and domains or to mark Safe senders and domains.
Note: Safe Sender lists are limited to 1000 entries and must be specified as full e-mail addresses because adding Safe Sending domains is not supported. Blocked Sender lists are limited to 500 entries, which can be full email addresses and/or email domains.
