I’m running the beta of Outlook 2015 and it’s visibly missing the whole scripting option. Has anyone thought of a way of still integrating SpamSieve? The junk mail filter on Outlook 2015 is GARBAGE.
Please see the Setting Up Outlook 2016 page. SpamSieve can filter the messages, but it won’t do so automatically when they come in because Outlook 2016 has removed the feature of applying AppleScripts from a rule. It is, however, possible to manually tell SpamSieve to filter a batch of selected messages. I’m also working on a way to have it automatically check the inbox for new messages that need to be filtered.
You could also try the new Outlook - Filter Mailboxes script.
