Should you update to Office for Mac 16.114?
Yes, this week. Office for Mac 16.114 is a security update Microsoft released on 14 Oct 2026 for Mac. It fixes 118 security flaws, 30 rated critical and 88 important by Microsoft.[1] None of them is known to be used in attacks.
It is the newest Office for Mac release, so it’s the one to have.
Should you update?
Yes, this week. Microsoft rates 30 fixes critical, and attackers study each release to work out what it fixed. Every security update closes holes that become public the moment it ships, so the risk of staying on the old version only grows. Waiting a week to see if others hit problems is a common habit; with a security update it’s the wrong trade.
Is Office for Mac 16.114 safe to install?
Yes. It’s Microsoft’s own security release, and updates rarely go wrong; a backup makes it painless if one does. The one unsafe way to get it is from a link: Microsoft never sends updates by email, text or pop-up, so install it only from Microsoft AutoUpdate (Help → Check for Updates in any Office app), or the App Store if Office came from there.
