We have a user who has recently changed their surname.
I changed the name in Sharepoint admin.
But the user cannot save to Sharepoint from Office apps as it comes up with her previous name login.
All logins to Office and Sharepoint are with a new name.
But it keeps coming up with the old name in the site when trying to save from Word for example. When clicking on SharePoint site in the word it comes up blank and the user cannot save directly to Sharepoint.
