Outlook Address book issue

Hi,

I need your help in order to resolve one of issue related to Outlook ( I assume) 

I made the changes in designation of a user in AD but it did not replicate in Outlook. Now I noticed whatever changes made in AD, it is not replicating in Global Address List of Outlook but changes are present inAll Users.

I think this is the issue with Offline Address Book .

can somebody assist?
