Adding contacts to another users Address Book in Outlook 2011 for Mac

I have a client who uses Mac products. They are currently using Outlook 2011 for Mac. The president of the company has assigned his personal assistant as a delegate. She can open his folders via her Outlook without issue. When she inputs new contacts for him on his Address Book via her Outlook, all appears fine. However, he never sees the new contacts. Thoughts and/or suggestions?

Thanks in advance!!!!

I'll bet he (at least) is setup as a pop3 account and, as such, everything is on his local drive including his contacts.  If this is true, she'll have to send new contacts to him via email:

@DavisMcCarn - Thank you for your response. I failed to mentioned to mention in my original post that all users are using Microsoft Office 365 and all users are setup with Exchange profiles in Outlook 2011.

@DavisMcCarn - she was given delegate authority into his account where she can add calendar, contact and task entries. The calendar and task entries appear, but not the contacts.
