Frequently Asked Questions

Why does Microsoft 365 say 'Unlicensed Product' after I just paid for it?

This usually happens if the Office apps on your computer are logged into a different Microsoft account than the one used for the purchase, or if the local license cache hasn't updated yet. Try signing out of all accounts in the Office app, restarting the app, and signing back in with the correct email.

How long does it take for a Microsoft 365 subscription to activate after purchase?

Typically, activation is instantaneous. However, in some cases involving bank delays or server syncing issues, it can take up to 24 hours for the payment to fully process and update the subscription status on Microsoft's servers.

What should I do if the Microsoft 365 installer hangs or gets stuck?

A stuck installer is often caused by network interruptions or conflicting antivirus software. Cancel the installation, restart your computer, temporarily disable your antivirus program, and try running the downloaded installer again as an administrator.
