We have a user with some issues opening Word documents. Word is showing a message every time it is opened that it is not the default app for documents, but it is set to default on all relevant file types. Icons are not showing as Word icons, instead showing as the default "white sheet" for documents, and in order to open a document from another program, the file has to be saved and opened independently. I have verified that his Office365 account is signed in correctly, run Office repair (Online), fully uninstalled Office then downloaded and installed a fresh version, and have had no change. This is also only happening on one profile, the Administrator profile seems to be working fine. Any thoughts?
