Mac mail cannot get outlook.com inbox message when using IMAP

Hi

I am suffereing from the same problem as many others when using Mac mail (the mail.app in OS X 10.9), that I cannot see messages in the inbox. Please see my details below:

1. I set it up correctly according to this: http://answers.microsoft.com/en-us/windowslive/forum/mail-email/how-to-set-up-mac-mail-to-sync-your-outlookcom/afdfe981-20c7-4d4a-b6b1-9329b27f018a?tm=1379009343708

2. In my first attempt, everything worked fine, I had all messages downloaded to all my default folders (including inbox, sent, draft) and all other created folders, and I seemed to have received new messages.

3. However, after a day it stopped receiving new messages (continued for a whole day).

4. As such, I deleted the entire directory that held the mailbox and re-started again.

5. This time, it only downloaded messages in some of the folders (in this case, all the created folders and the draft - but not the inbox nor the send folder). This has been going on for a whole day. At the moment, I still have an empty inbox...

Can you help plesae?

Many thanks and regards.
