It has come to our attention that a feature of the O365 mailbox (Clutter: https://blogs.office.com/2014/11/11/de-clutter-inbox-office-365/)  has been flagging some internal messages sent by the University as ‘clutter’. This means the message bypasses the inbox and is deposited in the “Clutter” folder. The tool is adaptive based on user activity and therefore customized to each user. Details of the algorithm are not known.

To prevent this we are putting some changes into production on the morning of June 2, 2016 (Thursday). Consultations with peer institutions suggest no appreciable impact on mail delivery performance from these changes.

If you have technical questions about this change specifically please contact email.ops@utoronto.ca
