Many people who have upgraded to Mac Outlook 2016 have expressed their disappointment that SpamSieve no longer works. This is because Outlook 2016 dropped support for AppleScript, which SpamSieve relies on to handle spam.

Reminder: Mac Outlook 2016 is part of Office 2016 for Mac, and is currently available only to Mac Office 365 subscribers. A full retail version of Microsoft Office 2016 for Mac will be available to purchase in September.
