Problem Description: Office 2024 Work Macos
I am currently on MacOS 15.7.2on two Macs and due to age I cannot update one of them to 26.2 and need to keep it with 15.7.2. I have Office (Desktop) 2024 on both and concerned with compatibility issues if the two machines are not on 26.2, and unsure if there are any compatibility issues between Office 2024 & MacOS 26.2

Likely Causes Behind Common Office Compatibility Issues Triggers
The Microsoft account or license context may not match the purchase or device.

Recommended Solution: Restoring Office After Errors
When to use this: Apply these steps when the symptoms match and you can access the relevant Microsoft account or administrator.
Since you're on macOS 15.7.2, verify if macOS 26.2 is newer and supported; if so, Office 2024 should work.
For the Mac that cannot update to 26.2, ensure Office versions are compatible with macOS 15.7.2.
Check specific compatibility details to avoid issues on older machines.
Alternative Solutions for Broader Office Compatibility Issues Workarounds
Retry the Microsoft-side steps after restarting the app and device.
Test the same action in a private browser session or a new blank file to isolate account vs file issues.
Run Quick Repair, then Online Repair from Programs and Features if the app still fails.
Capture exact error text and screenshots before contacting Microsoft Support or your administrator.
Working with WPS Office: Using WPS While Office Is Unavailable

WPS Office cannot replace Microsoft account, activation, or cloud fixes for this scenario. It remains one of the best free Microsoft Office-compatible alternatives for opening and editing local files.
Download and install WPS Office from the official website.
Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.
Save a working copy locally while Microsoft-side issues are resolved.
Return to Microsoft Office after the primary fix succeeds.
If you need a practical local workspace in the meantime, try WPS Office.
Prevention Tips for Avoiding Repeat Office Compatibility Issues
Keep one primary Microsoft account for subscriptions and Office sign-in.
Install updates for Office and Windows before retrying failed workflows.
Back up important files before repair, reset, or reinstall actions.
Document exact error messages before the next troubleshooting attempt.

Should I reinstall Office before trying these steps? Not first. Confirm account, license, and the exact error before reinstalling.
What should I send to Microsoft Support? The affected account email, device type, Office version, exact error text, and screenshots with personal data hidden.
