Office-Reset is a free downloadable tool that you can use to fix problems and errors encountered with Microsoft Office for Mac apps. This includes Word, Excel, PowerPoint, Outlook, OneNote, OneDrive, Teams and AutoUpdate. The tool can help fix app launch errors, freezes, hangs, crashes, bad plug-ins, corrupt templates, performance issues, and confusing error messages.
You can tell Office-Reset to fix a specific app, or you tell it to perform a 'factory reset' - essentially putting Office back to the same pristine state as when you first installed it. There's also an option to completely start over, where the tool can remove every app, cache, container, preference and keychain entry that Office may have created while it was running.
Office-Reset does not delete your documents and workbooks. The tool doesn't have ads, an upsell, collect your data, or install software that you don't want. It simply runs, fixes, and quits.
