Newer versions of Outlook present a "Focused" view of your inbox, that tries to sort emails that require your attention (e.g. from people you frequently correspond with) into a "Focused" inbox and emails that aren't important (e.g. email from mailing lists) in an inbox labeled "Other".
On the whole, it does an okay job.
However, it's far from perfect: Sometimes important emails end up in my "Other" inbox, while some unimportant emails end up in my "Focused" inbox. Is there a way to configure Outlook to change what it categorizes at "Focused" and "Other"?
