Not Receiving Verification Code Email

[steiergroup]

We have created 2 new profiles for new employees and when clicking on the verify button for the email verification code, they are not going into their email. Our IT company has been working on this too. I tried using my personal email address and I got the verification email. Why am not getting them on these new users?

@steiergroup, in my experience with this issue, the root cause has always been one of two things: 

email arrives to junk mail

organization's network security settings are preventing delivery
