I've been using Gmail via Outlook for some time with no problems. I have Office 365 and my Gmail is attached by the default method. However I've just caught Gmail marking random (as far as I can see) emails as junk and putting them in a junk folder which seems not to be visible from Outlook. The folder says that any messages left in it are deleted after 30 days so I can't see how long this has been going on for. Outlook seems to list the same folders as are shown by Gmail (accessed via Chrome) but the Junk E-mail folder remains empty on Outlook. I've see similar posts but not quite this specific issue! Help!
