This Microsoft update will impact any user who is using Office 365 and Outlook.
If you have Office 2010/2013 installed you need all the latest Office updates installed otherwise Office 365 will no longer work.
The changes will affect all Outlook users who are not using a 2016 version to connect to an Office 365 mailbox. The announcement states that the protocol previously used by Outlook 2007, 2010, and 2013 to connect with Office 365 will no longer be supported by Office 365 after October 31, 2017.
