Yesterday I installed the Maori keyboard for Windows, and accidentally set my display language to Te Reo. After a bit of a struggle (my introductory Te Reo lessons weren't much of a help with Windows Control Panel names!) I managed to switch the display language back to English.
However, this doesn't seem to have worked for Office 365 - all of the menus are in Te Reo! Any idea how I can fix this?
