Thanks for getting back to me,
I checked my servers IP on mxtoolbox and it's not blacklisted.
Outlook's Error message:
Server error: '554 5.7.1 <email address>: Relay access denied'
mail log: (I have taken out the ip's and other information I deem to be sensitive)
Sep 02 16:30:08 s10 postfix/smtpd[13073]: connect from xxxxxx.com[ip]
