Junk Email Options in Outlook on Windows

IT Services utilizes the anti-spam and anti-virus capabilities of Office 365, which block delivery of unwanted emails to your main inbox in Outlook 2016. You can manage some elements of this service using the Outlook Junk Filter settings, including enabling higher levels of filtering.

There are also instructions for Outlook for Mac and Outlook on the Web.

All users who previously checked spam using spamq.uwindsor.ca or Spam Digest email will need to follow the instructions in this knowledge base article. That functionality has been retired as of May 2020. 

Checking Junk

It's a good idea to regularly review messages in the Junk Email folder to check for legitimate messages that were incorrectly classified as junk. All junk email will be delivered to the Outlook folder titled "Junk Email"

If you find a message that isn’t junk, drag it back to the Inbox or any folder. You can also mark the item as not junk by doing the following:

  • Click Home > Junk > Not Junk.

Change Level of protection in Junk Email Filter

The Junk Email Filter in Outlook identifies messages that are likely junk and moves them to the Junk Email folder. You can easily enable additional junk email protection or automatically delete junk email.

By default, the personal Junk Email Filter protection in your mailbox is set to No Automatic Filtering. You can make the junk filter more aggressive (i.e. turn it up above the system-level junk mail filtering built into Office 365) so that it catches more junk messages. The higher you set the protection level, the greater the risk of some legitimate messages being identified as junk and moved to the Junk Email folder.

  1. Click Home > Junk > Junk Email Options.

  2. Choose the level of protection you want.

    • No Automatic Filtering     Default level. Only Office 365 system-wide filtering is applied. Even if you use this to turn off the additional Junk Email Filter in your mailbox, messages are still evaluated for basic security / spam identification by Office 365 and against email addresses in your Blocked Senders List.

    • Low     If you want to filter more messages that are probably junk, select this option.

    • High     If you want aggressive junk filtering, but don’t want to restrict messages to only those from senders on your safe lists, select this option. We recommend you occasionally check the Junk Email folder to make sure that a message you wanted isn’t moved in error.

    • Safe Lists Only     This is the most restrictive option. Any message that isn't from someone on your Safe Senders List or isn't to a mailing list on your Safe Recipients List, is classified as junk

Adding emails to Safe Sender List

Email addresses and domain names in the Safe Senders List are never treated as junk email, regardless of the content of the message. You can add your Contacts and other correspondents to the Safe Senders list to confirm you'll always receive their messages in your inbox.

To add people to your Safe Senders List, do the following:

  1. On the Home > Junk Junk E-mail Options > Safe Senders tab

  2. Click Add button

  3. Enter email of your recipient

  4. Press OK

On the Safe Senders you can also click Automatically add people I email to the Safe Senders List box to ensure anyone you email is never treated as junk.
