Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
Are you using a Mac or Windows computer?
If Windows, open any Office app (Word, Excel, etc.), then go to File > Account. Scroll down and click Sign out. Restart your computer, then sign back in using the correct Microsoft account.
If Mac, open Word or another Office app, click your profile icon or account name in the top-right corner, select Sign Out, close the Office apps, then reopen one and sign in with the correct Microsoft account.
If the issue persists, go to https://account.microsoft.com/services.
Can you confirm whether your Office license or subscription appears there and is listed as active?
