activation error

For Office activation errors on a Mac, use this sequence:

1. Confirm the Mac has internet access by opening a browser and loading https://www.microsoft.com.
2. Quit all Office apps.
3. Verify the account used to sign in is the account that has the Microsoft 365 license:
   • Sign in at https://account.microsoft.com/services
   • Select Install Microsoft 365 or Office
   • If a license is listed there, that is the correct account to use in Office.
4. Reset Office credentials:
   • Open Spotlight
   • Search for and open Keychain
   • Search for Office
   • Delete the data license file
5. Run the License removal tool, then open an Office app and complete activation again.
6. If the Mac is signed in with a network account such as Open Directory, sign out and use a local macOS user account instead. Office for Mac may fail activation because it cannot write credentials to a read-only keychain.
7. If Office is activated but still keeps prompting for activation, quit the app, restart it, and if needed repeat the Keychain cleanup and run the license removal tool again.

If the exact error code is available, the next steps can be narrowed further:

• 0xD000000C: usually resolved by internet check, quitting Office, running the license removal tool, and using a local account instead of a network account.
• 0xD000001c: rename the Mac in Apple icon > System Preferences > Sharing, remove invalid characters, restart, then activate again.
• No license found or sign-in activation issues: sign out and back in with the licensed Microsoft account.
