My first suggestion is to add the sender of those messages to your safe senders list. That way emails from that address will never end up in the junk folder.

Beyond that, Microsoft purposely keeps Outlook's junk classification methods undocumented. No one knows what they are exactly. Therefore, it is impossible to tell you what to do to avoid the junk folder.
