We want to read data from "State/Province" attribute from AD.
However, this attribute was missing in SharePoint User Profile Service application. So in order to achieve that, we created a custom property for "State/Province" and mapped through "st" attribute of AD.
After running full synchronisation, only 730 user's "State/Province" property was updated out of 5478 users. Also, we have checked in the AD and "State/Province" attribute is already updated for all users.
We are working on SharePoint 2016 Enterprise.
Any help is much appreciated.
