Incoming calls name of contact from Exchange Server not showing topic

Hi all,

I'm syncing my samsung galaxy s4 with a exchange server for email,calender and contacts. This is working perfectly. Only when colleague is calling me i see only this telephone number and not his/her name. I can search for this colleague and add him in my local contact list but i don't wanna do it for all my colleagues.

Does anyone have a solution for this problem?

Thanks!
