New users added to AD are imported successfully into SharePoint 2016. Updating user information in AD (ex. title, department) does not get imported into SharePoint2016. Not sure when this behavior started but has been going on for a few months. SharePoint 2016 sits on Windows 2016. Only changes would be installing server and SharePoint 2016 patches. UPS is started and we are using AD Import. The service account associated with UPS has full control of the site web app and mysites. I have not been able to locate any errors.
How can I fix this?
