APPLE updates V27 - INTEL Microsoft WORD and EXCEL will no longer work.

Office 2019, and Office 2021, and later have support for Apple silicon:

Best to get your Microsoft support and questions via the Microsoft forums, though. They know their apps best.

If you are trying to use old versions of Microsoft 365 or Office, you might run into problems, above and beyond the question of Intel-only vs. Universal 2 or Apple Silicon versions.

"Note

Starting July 13, 2026, Microsoft 365 subscribers on macOS, iPhone, and iPad, and those with non-subscription software, including Office 2021 or Office 2019 on macOS might notice that Office apps (Word, Excel, PowerPoint, Outlook, or OneNote) can open and print files, but cannot edit, save, or create new files – called “reduced functionality mode”. For more information, go to Update Microsoft 365 or Office on your macOS or iOS device."
