Assosciating my Microsoft purchase from Apple

This usually means the Apple App Store purchase is active, but it is linked to a different Microsoft account than the one currently signed in to Excel. The 0x0 error on Mac can also occur when Office needs updating or the current macOS/Office combination is no longer supported.

Try this in order:

1. Sign out of Office completely
   • In Excel or another Office app, sign out.
   • Then sign back in with the Microsoft account that was most likely used when the Apple purchase was first associated.
   • If multiple Microsoft accounts exist, use Sign in with another account.
2. Restore the Apple purchase again
   • In the Office app, use Activate previous purchase / Restore previous purchase.
   • This is the recommended step for Apple-purchased Microsoft 365 subscriptions when Office cannot validate or associate the purchase.
3. Confirm the subscription is active in Apple
   • If Apple shows the Microsoft 365 subscription as active, continue with the restore flow.
   • If it has expired, renew it first.
4. Check whether the correct Microsoft account has the license
   • Sign in to https://account.microsoft.com/services.
   • Select Install Microsoft 365 or Office.
   • If a Microsoft 365 or Office license appears there, that is the correct account to use in Excel.
   • If no license appears, search all email accounts for the Microsoft purchase/confirmation message to identify the associated account.
5. If Office still cannot activate, reset Office credentials on the Mac
   • Open Spotlight.
   • Search for and open Keychain.
   • Search for Office.
   • Delete the data license file.
   • Then try activation again.
6. Address the 0x0 error
   • If Office was installed from microsoft.com, update using Microsoft AutoUpdate: Finder > Applications > Microsoft AutoUpdate > Update All.
   • If Office apps were installed from the App Store, open App Store > Updates and update the Office apps there.
   • Microsoft’s resolved guidance for 0x0 / License Not Found on macOS also requires macOS 12 or higher.
7. If the purchase still cannot be associated
   • For Apple-purchased subscriptions, use the restore-purchase article first.
   • If the issue persists after restoring and signing in with the correct Microsoft account, contact Microsoft Support.

Important:

• If the subscription was purchased through Apple, billing is managed by Apple.
• The association problem is usually caused by signing in with the wrong Microsoft account at the time of activation.
