We have a staff member that moved from Korea to China and their numbers changed. Everything updated OK in AD except for the mobile number. If I try to change the mobile number, it updates for 2 days but then reverts back to the Korea mobile number. Seems like something is overwriting the AD mobile attribute. Any ideas guys? I have checked ADSI and exchange and they both update when I make the change in AD mobile attribute, but like AD, they revert back after 2 days. We also have cisco jabber that integrates with AD so the new mobile should reflect in jabber but doesnt.
