SPAM Filtering

Microsoft Defender to Begin Filtering Spam This Summer

Microsoft Defender logo.As one of the final steps in our cloud email migration project, OIT will soon retire our legacy Cisco IronPort spam filtering and replace it with Microsoft’s Defender spam filtering service. While providing better real-time spam filtering and detection using artificial intelligence, this transition also means new ways of managing your spam quarantine. Keep reading to find out more!

Once the transition is complete, you will no longer need to go to to view and manage your spam quarantine. Instead, you can manage your spam messages directly in Outlook or Webmail via your Junk email folder. No more switching back and forth! Also, you won’t have to forward suspected spam and phishing messages to Once we switch to the new service, a “Report Message” button will appear in your Outlook toolbar as well as within Webmail. Just click the button when viewing the message, and it will be immediately reported and moved to your junk folder.

Deployment of this new system is slated for later this summer once testing is completed. We hope this new spam filtering platform makes it easier for you to manage your mailbox and keep spam at bay. Of course, always stay vigilant when checking your email, and keep an eye out for phishing and other suspicious email schemes. The IT Help Desk is always here to help you with any concerns you may have with any suspicious messages.
