However when I try to use an @hotmail.co.uk I get no messages in my inbox. It downloads messages perfectly fine from the Deleted, Junk and Sent folders but it doesn't grab anything from the inbox folder. 

Suggestions? I'd appreciate it if you didn't advise me to set it up again or that it's a config option. I've set it up multiple times with the same result and it can't be a config problem as A) it works perfectly correct with an @outlook address and B) I wouldn't get any emails from the Deleted, Junk and Sent folders if it was a config problem.

Looks like there's a problem with specifically @hotmail.co.uk addresses. Haven't yet tried an @msn address or any other regional Hotmail.
