On​  August 26, 2019 Information Services switched spam filtering providers from Google to Microsoft.  As part of the switch the spam quarantine notices are no longer sent.

There are multple way for folders to be created in your mailbox, so it is possible for some users to have multiple Junk E-Mail folders.  Users that want to can remove any folders they do not want by right clicking the folder and selecting Delete Folder. 

The ​Microsoft service analyzes every incoming email based on various attributes and details, including the reputation of the sender, the email content, presence of malware, phishing likelihood, and more to assign a score that indicates the likelihood that this email is spam or malware.  Any email with malware or is part of a phishing campaign is auto-deleted.  All other emails are assigned a score based on the likelihood that the email is spam.  DePaul administrators periodically review and adjust the filter settings to best manage the balance between which emails get delivered (even junk email) vs. which are discarded.
