Excel 16.114 for Mac: What Changed, 16.114.1 and License Issues

Excel 16.114 is the October 2026 release of Excel for Mac, shipped as part of Office for Mac version 16.114 (build 26101123), which Microsoft’s release notes date to October 14, 2026. For Excel itself it contains no new features, only “quality and performance improvements”, and it was followed on October 22, 2026 by a maintenance update, 16.114.1 (build 26102031), which is the version most Mac users should now be on.

Much of the search interest is not about features at all. Since 16.114.1 arrived, a number of Office 2021 for Mac owners have reported that Excel stopped letting them edit or save files. Below is what the release actually contains, how to check and update your copy, and what is known (and not known) about the license problem, as of October 24, 2026.

What is in Office for Mac 16.114

Microsoft publishes one set of release notes for the whole Office for Mac suite, with a section per app. For 16.114, the notes break down roughly like this:

The Outlook changes are the most visible part of the release. According to the release notes, you can now choose a supported third-party online meeting provider when creating a calendar event, and supported Microsoft 365 apps can appear dynamically in Outlook’s left rail. Fixes include restored Gmail keyboard shortcut support for snooze times and corrected calendar times for Morocco after its September daylight-saving change.

If you were expecting a new Excel function or Copilot feature in 16.114, it is not in the notes. The most recent Excel feature entries we found predate this release: 16.112 (August 11, 2026) let Copilot in Excel ground analysis in governed Power BI data, and Copilot-related changes followed in September.

What 16.114.1 changed

The 16.114.1 entry, dated October 22, 2026, lists only a “Resolved issues” section with quality and performance improvements. Microsoft does not describe specific bugs fixed in that build. The update history page lists 16.114.1 (26102031) along with per-app update packages, including one for Excel.

How to check your Excel version on a Mac

1. Open Excel.
2. In the menu bar, choose Excel > About Excel.
3. Read the version line. It shows the version (for example, 16.114.1) and the build number in parentheses.
4. Compare it with Microsoft’s update history for Office for Mac to see whether a newer build exists.

How to update to the latest Excel build

Microsoft updates Office for Mac through Microsoft AutoUpdate (MAU), unless you installed the apps from the Mac App Store. The official steps from Update Office for Mac automatically:

1. Open Excel (or any Office app) and choose Help > Check for Updates.
2. If that menu item is missing, install the latest Microsoft AutoUpdate tool from Microsoft and try again.
3. In the AutoUpdate window, turn on the option to automatically keep Microsoft apps up to date if you want future builds installed for you.
4. If you installed Excel from the Mac App Store, update it from the Updates section of the App Store instead.

Not sure which install you have? Microsoft suggests running mdls -name kMDItemAppStoreReceiptType in Terminal against the app’s path. A result of “(null)” means you should use AutoUpdate; App Store copies report a receipt type.

Check your macOS version first

Microsoft’s macOS requirements page says that starting with the September 2025 update (16.101), macOS Sonoma (14) or later is required to receive updates to Word, Excel, PowerPoint, Outlook and OneNote. If your Mac runs an older macOS, Office keeps working, but it stops receiving updates, including security fixes. We did not find a Microsoft page that restates the requirement specifically for 16.114, but nothing we found suggests it has been relaxed.

The Office 2021 license problem after 16.114.1

This is the part to read carefully if you own a one-time-purchase copy of Office 2021 for Mac.

What users are reporting

On Microsoft Q&A, several threads posted in the days after the 16.114.1 release describe the same pattern: after updating, Excel and the other Office apps showed a “No License Found” message or asked the user to upgrade to Microsoft 365, and editing and saving were blocked. One widely viewed thread is titled Office 2021, release of 16.114.1 - License Removed.

Some commenters in that thread say that going back to the 16.114 build restored editing, and that they then turned off automatic updates. Treat this as anecdotal. It is not Microsoft guidance, it depends on getting an installer from a trustworthy official source, and it leaves you on a build that will not receive further fixes.

Why the timing matters

Microsoft’s end of support page for Office 2021 says support ended on October 13, 2026, with no extension and no extended security updates. After that date Microsoft no longer provides security fixes, bug fixes or technical support for Office 2021, and no further Office 2021 software updates. The same page says the Office 2021 apps will continue to function. Office Watch and other outlets reported the same date.

16.114 shipped the day after support ended, so it is reasonable to suspect the two are connected. However, as of October 24, 2026 we found no official Microsoft statement confirming the cause of the license errors, saying whether the behavior is intended, or announcing a fix. That may change, so check the Q&A threads and Microsoft’s release notes for updates.

What you can do, using official routes

1. Confirm your license still appears in your Microsoft account under Services & subscriptions, signed in with the account you used to redeem Office 2021. Microsoft moderators have noted that a retail Office 2021 for Mac license is tied to the account that redeemed it.
2. Contact Microsoft support with your version and build number from Excel > About Excel. Even with Office 2021 out of support, a license that disappears after an update is worth reporting.
3. If support directs you to it, Microsoft has an official license removal tool for Office for Mac that clears stored license files so you can sign in and reactivate. Have your Microsoft account details ready first, and only use the tool from Microsoft’s own support site.
4. Avoid “fixes” from download aggregators or sites offering modified installers. Several of them rank for “16.114” searches right now; they are not official and can carry malware.

Longer-term options

Because Office 2021 no longer gets security updates, Microsoft points people to Office 2024 (supported until 2029, according to the coverage we reviewed) or a Microsoft 365 subscription. Either way you get current builds such as 16.114.1 with security fixes. Which makes sense depends on whether you want Copilot and cloud features, but that is a separate decision from fixing today’s error.

Bottom line

For Microsoft 365 and Office 2024 users, Excel 16.114 and 16.114.1 are routine maintenance updates with no new Excel features, and installing them through Microsoft AutoUpdate is the right move. For Office 2021 for Mac owners, the update has coincided with reports of lost licenses, and as of October 24, 2026 Microsoft has not publicly explained why. Check your account, contact Microsoft support, and watch the official release notes before reaching for unofficial workarounds.
