Fix Excel for Mac Activation Required Error and Missing Workbooks
Question details
The user is experiencing an activation loop in Excel for Mac where the app repeatedly asks for activation despite being logged in, while recent workbooks appear missing.
- Product
- Excel for Mac
- Device & OS
- Mac
- Scenario
- Opening Excel files and trying to access recently saved workbooks in Microsoft 365.
- Observed behavior
- Excel reports that activation is required even though the account is already signed in. Furthermore, workbooks are missing from Microsoft 365, leading the user to believe recent work has been lost.
Verify that your Mac is connected to a stable internet network and check your Microsoft account online to ensure your Microsoft 365 subscription is currently active.
Restart Mac and Check Account Connection
A simple system restart and status check can resolve temporary sync glitches between Excel and the Microsoft license server.
Often, Excel for Mac gets stuck in an authentication loop due to background process errors or network interruptions. Restarting the system forces the Office suite to re-verify the active login session.
Ensure your Mac's Wi-Fi or ethernet connection is active and stable.
Click the Apple menu in the top left corner and select 'Restart' to reboot your system.
Open Excel, click on your profile icon or the 'Excel' menu, and confirm that the account displayed matches the one holding the Microsoft 365 license.
Locate Unsynchronized or Missing Workbooks
Use this method to find workbooks that may not have synced properly to Microsoft 365 due to the activation error.
Use the License Removal Tool
If the activation loop continues after a restart, clearing the corrupted license files is necessary.
Use WPS Office to Open Excel Files Without Activation Issues
If you are stuck in a Microsoft 365 activation loop on your Mac, try WPS Office. It is a free, lightweight alternative that offers a familiar interface, seamless migration, and full compatibility with your existing Excel files.
- 1. Download WPS Office: Visit the official WPS website and download the Mac version of WPS Office.
- 2. Install the application: Open the downloaded installer and follow the instructions to install WPS Office on your Mac.
- 3. Open your workbooks: Launch WPS Spreadsheet and select 'Open' to access your existing .xlsx files without any activation prompts.
Frequently Asked Questions
Why does Excel for Mac keep asking me to activate when I am logged in?
This usually happens due to corrupted local license files, a disrupted connection to Microsoft's authentication servers, or a conflict if multiple Microsoft accounts are signed into the Mac.
Will I lose my workbooks if my Microsoft 365 subscription expires?
No, your locally saved files remain on your Mac. However, you will lose the ability to edit them in Excel until you renew the subscription or use an alternative software like WPS Office to open and edit the .xlsx files.
Where does Excel for Mac save AutoRecover files?
AutoRecover files are typically saved in a hidden Library folder. You can access it by opening Finder, selecting 'Go to Folder', and entering: ~/Library/Containers/com.microsoft.Excel/Data/Library/Preferences/AutoRecovery/.
