Office 365 (Outlook) - Junk Email Folder

The Junk Email Filter evaluates each incoming message based on several factors.These can include the time when the message was sent and the content of the message. 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. If you find a message that isn’t junk, drag it back to the Inbox or any other folder. In order to make changes to your junk email filter, please do the following (scroll further down to see instructions for Outlook on the Web):

Note: Parkland College employs additional spam email filtering through use of Mimecast. For additional information on that, please see Parkland College Email Spam Filter.

Installed Outlook Application:

To change the options for the Junk Email Filter, do the following:

    From within the Home tab, in the Delete group, select Junk > Junk Email Options.


By default, the protection level is set to No Automatic Filtering. You can make the filter more aggressive by changing the level of protection that it provides. The higher you set the protection level, the greater the risk of some legitimate messages being identified as junk and moved to the Junk E-mail folder.

While the Junk Email Filter checks your incoming messages automatically, Junk Email Filter Lists let you control what is considered spam. You can add names, email addresses and domains to these lists so the filter doesn’t check messages from sources you trust, or blocks messages that arrive from specific email addresses and domains you don't know or trust. To access these lists, click on the various tabs to the right of the Options tab as seen in the picture above.
Safe Senders list: Email addresses and domain names in the Safe Senders List are never treated as junk email, regardless of the content of the message.

Safe Recipients list: If you belong to a mailing list or a distribution list, you can add the list sender to the Safe Recipients List.

Blocked Senders list: You can easily block messages from particular senders by adding their email addresses or domain names to the Blocked Senders List. The blocked sender limit is 500.

International list: Some email you receive might be written in languages you are unfamiliar with and don't want to read. You can block messages such as these by selecting the various options in the International tab.

Outlook on the Web:

There are fewer junk filtering options if you are using Outlook on the Web.  To access, click on the Settings icon >View all Outlook settings>Junk email.  From here, you can add or delete addresses from the Blocked Senders and Domains list and the Safe Senders and Domains list. You can also set up a couple of filtering and reporting options.
