The WindowsForum thread discusses issues with OneDrive on Windows build 10122, with users sharing their experiences. While some users report that OneDrive works fine after a clean install, the original poster faces problems with a greyed-out icon and inability to access it on their PC, despite online and mobile access. Through troubleshooting and multiple clean installs, the user eventually gets many apps working properly, though some issues like Cortana availability remain, and other users express sympathy and appreciation for the shared updates.
