Wondering if anyone can help please. I have an on premise SharePoint 2013 environment which users used to access using: "DOMAIN\FirstName.LastName" however the organisation recently made a change and users are now authenticating using "[email protected]". Since this change users are being continuously prompted to login when accessing SharePoint via the browser or opening a document stored in SharePoint using office.
I have tried deleting the user profile service and completely recreating this however still no luck. Users are using a mix of IE and Chrome however I have checked all IE settings are set and also added the credentials to the credential managers, however still no luck.
Appreciate any help than can be provided.
