Junk (Spam) Mail Filtering


Office 365 offers automatic anti-spam and anti-virus filtering. Once all incoming e-mail goes through UCR's graylisting and realtime blocking list filters, any messages which are not blocked by UCR's filters will then go through Microsoft's anti-spam tagging filters to further mark spam content. At that point, any message that is identified as spam will be labeled as "Junk Email", and moved into the Junk Email folder.   

You can access your junk email messages by clicking on the Junk E-Mail in the left hand menu in the O365 web interface. If you find that you are receiving more spam/junk in your Inbox than you should, Computing recommends taking the time to mark the message(s) as junk and not simply delete it.  

If you continue to receive spam messages from the same sender, you can block unwanted emails or senders by creating a filter or rule so they are sent directly to the trash.  

Since no spam/junk filter is 100% accurate, it is recommended that you periodically check your Junk Email folder weekly for legitimate e-mail messages.  If you find legitimate emails in your junk email folder, C&C recommends to mark the message incorrectly marked as 'Not Junk', ensure the sender is added to your contacts, and consider creating a filter or rule to allow emails from that sender to be delivered to your Inbox.

Lastly, although many spam e-mails have an unsubscribe link in the message, it is not advisable to "Unsubscribe" to spam messages, this reply will let the sender know they sent the email to a legitimate address and more spam may result.
