Outlook 2007 not receiving certain emails

Emails are receiving fine on laptop that has outlook 2013 and they are also coming through on iphone.

outlook 2007 shows that they are being downloaded but they wont show in the inbox.

Junk email folder is always empty? are they going to junk and getting auto deleted?

I've tried going into safe mode with outlook but no success, also checked my rules and nothings there either.

The computer also doesn't have any anti virus that would delete them as its only got Microsoft security essentials.

I was able to fix it by going into junk mail settings and unchecking the delete junk mail.

Not sure why it was enabled but any email going into junk folder was auto deleted
