One of my users started having a problem this morning with all of his inbound email being redirected to the Outlook RSS Feeds folder. He has no rules or RSS Feeds configured. I ran the Microsoft diagnostics.office.com tool, as well as an Office quick repair, but the incoming mail continues to go to the RSS Feeds folder.
We're running Exchange in Office 365. When I log into his Outlook Web, I see the same behavior. Exchange mail trace shows the email being successfully delivered to RSS Feeds, but it is not giving me any clue as to why. Ideas?
