SharePoint 2016 user profile service issue

I have the User Profile service for Sharepoint 2016 completely setup. I run the full import and users were populated. I now update a user in AD and it does not update in SharePoint.

The only indicator I can find is a couple of log entries similar to:

Exception while updating properties for ‘XXXX\XXX’: Property: MailNickName, Exception Microsoft.Office.Server.UserProfiles.PropertyNotDefinedException: Property Not Defined: MailNickName. An administrator must create this property in the Profile Administration tool.

this is coming up for most users. Any thoughts on where to start looking for this issue.?
