Daily activation of my 365 license

For Microsoft 365 Apps that repeatedly ask for activation, use the following steps that apply to Mac and general account/licensing issues.

1. Confirm the correct subscription and license

• Sign in to the Microsoft 365 portal in a browser with the same Work or School account used on the Mac.
• Verify that the subscription is active and that it includes the right to install desktop apps (for example, Microsoft 365 Personal/Family or a business plan with apps). A Microsoft 365 Basic subscription does not include desktop apps and will always fail activation on the device.

2. Sign out of Office and sign back in

• Open an Office app (for example, Word).
• Go to the account/profile area (File → Account or the name/profile icon at the top, depending on platform).
• Sign out of all accounts listed.
• Close all Office apps.
• Reopen an Office app and sign in only with the Work or School account that has the valid Microsoft 365 license.

3. Make sure the account has a license assigned (for business/enterprise) If this is a work or school subscription and an admin manages licenses:

• An admin should go to the Microsoft 365 Admin Center → Users → Active users.
• Select the affected user → Licenses and apps.
• Under Licenses, ensure the appropriate Microsoft 365 license is checked and Save changes.
• If a license is already assigned, clear the checkbox, save, then re‑check it and save again to refresh the assignment.

4. Remove unused devices tied to the license If the license is used on too many devices, activation prompts can recur.

• Go to https://myaccount.microsoft.com/device-list and sign in with the same account used for activation.
• Remove any unused devices.
• Restart the Mac and try activating again.

5. Reset the activation state (if using Microsoft 365 Apps for enterprise) If the issue persists, reset the Microsoft 365 activation state and then sign in again to re‑activate. Follow the steps in the “Reset activation state for Microsoft 365 Apps for enterprise” article referenced in the context.
6. Check for network/proxy issues (if using corporate network) If the device is behind a proxy or restricted network, activation calls may fail and cause repeated prompts. Ensure required Microsoft 365 URLs and IP ranges are allowed as described in the network and proxy guidance in the context.

If the subscription is confirmed active, the correct account is used, the license is properly assigned, unused devices are removed, and activation state has been reset, the apps should stop asking for activation daily.
