After a serious database corruption, I've succeeded rebuilding my Outlook identity (with the great help of Diane Ross).
I've moved now tons of messages that were 'On my computer' into folders of an IMAP email account (Hover). However, Outlook doesn't seem to 'sync' folders automatically. It's only when I go into a certain folder and press 'Synchronize now' (by right clicking) that it synchronizes all emails. This is however not feasible, as I've 5000+ folders. Any way to 'force' Outlook to synchronize all messages to make sure they are 'synchronized'/pushed into my IMAP email account?

(I'm receiving new messages in my inbox without any problem).
