Is the Outlook Junk Mail Filter needed when our mail server is hosted on O365?
We are running into problems white listing domains. I've found that the Junk mail filter in outlook will still send email to the Junk mail folder even if the server has tagged that email with a SLC Rating of -1 (a rating that bypasses the junk mail filtering on the server). I'm now wondering if the Junk Mail filter in outlook even serves a purpose if our email is already getting filtered by Microsoft.
