Hi everyone I keep running into the infamous. Delivery is delayed to these recipients or distribution lists It only happens to one user and so far its only one address he has the issues with. Its to a ( user@somethingsupplies.biz. ) Sometimes it takes all day to get the e-mail to the person. How would i go about figuring this out?

Another user in your org can send to this external user without delay? If this is the case than you need to work with this external company to see if they're greylisting\throttling your particular user.

Well i personally have sent a few to this user myself and i'm trying to recreate the problem myself. Just a waiting game at this point.

Sure, you can also go to https://www.testexchangeconnectivity.com/ and perform an inbound test agains this domain to see if it's an issue with your domain.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
