Microsoft has released an out-of-band Office update to fix a known issue that caused Word, Excel, and Outlook to crash after installing the KB5002700 security update for Office 2016.

The company acknowledged these problems following user reports on social media that Office apps no longer open after applying the April 2025 security updates.

“We’re experiencing an issue on Windows 10 with Office 2016 where Word and Excel no longer open,” one impacted Office user said.
