Question details

Excel on macOS fails to recognize a previously activated, one-time Office Home & Student purchase license, even though Microsoft Word continues to function correctly without activation prompts.

How to Fix Excel Not Recognizing Purchased Office License on Mac

Product: Microsoft Excel (Mac)
Device & OS: macOS
Scenario: Opening Excel to view or edit spreadsheets after having previously purchased and successfully activated Microsoft Office.
Observed behavior: Excel prompts the user to activate the software or states the license cannot be found, while other Office apps like Word recognize the license perfectly.

Before you start

Ensure you have the exact email address and password for the Microsoft account associated with your Office Home & Student purchase, and completely quit all Office applications before proceeding.

Solution 1Recommended

Clear Office Credentials from Mac Keychain Access

Use this method to remove corrupted activation files cached in macOS Keychain, forcing Excel to fetch the correct license details.

Often, the Mac Keychain holds onto outdated or corrupted Microsoft credentials, causing a mismatch where one app works (like Word) but another fails (like Excel). Clearing these entries forces a fresh license validation.

Close all Office applications

Right-click the Excel and Word icons in your Mac Dock and select 'Quit' to ensure no Microsoft applications are running.

Open Keychain Access

Open Finder, navigate to Applications > Utilities, and double-click the 'Keychain Access' app. Alternatively, search for it using Spotlight (Cmd + Space).

Search and delete Office credentials

In the Keychain Access search bar, type 'Office'. Select any items named 'Microsoft Office Identities Cache' or 'Microsoft Office Identities Settings', right-click them, and select 'Delete'.

Reopen Excel and sign in

Launch Microsoft Excel. You will be prompted to sign in. Enter the Microsoft account credentials associated with your original Office purchase to reactivate the license.

Clear Office Credentials from Mac Keychain Access

Safe Deletion: Deleting these Keychain entries will not affect your spreadsheets or data. It only resets the login tokens.

Solution 2

Run the Microsoft Office License Removal Tool

If clearing the Keychain manually does not work, this official tool scrubs all hidden license files from your Mac so you can start fresh.

Frequently Asked Questions

Why does Word work but Excel asks for activation on my Mac?

This happens when the local authentication tokens in macOS get corrupted or out of sync. Word might be reading a cached token that is still valid, while Excel tries to generate a new one and fails. Clearing your Mac's Keychain credentials usually syncs them back up.

How do I verify which account owns my Office Mac license?

Go to account.microsoft.com/services in your web browser and sign in. Look under the 'Products you've purchased' section. If your Office Home & Student license is listed there, that is the exact email address you must use to sign into Excel.

Will removing Office credentials delete my Excel files?

No. Deleting Keychain entries or running the License Removal Tool only affects the login and activation data. Your actual Excel workbooks (.xlsx files) stored on your Mac's hard drive or iCloud will remain completely untouched.

Does the License Removal Tool uninstall Microsoft Office?

No, the License Removal Tool only scrubs hidden license and activation files from your system library. It does not uninstall the actual Excel, Word, or PowerPoint applications from your Mac.
