Unable to sign in to the Office Apps

Use these checks and steps to resolve the sign-in issue.

1. Confirm the correct type of account is used
   • Office apps require either:
     • A personal Microsoft account that owns a Microsoft 365/Office license, or
     • A work or school account assigned a Microsoft 365 license.
   • Many people have both types of accounts. Make sure the email entered in the Office sign-in prompt is the one associated with the active Microsoft 365 or Office subscription.
2. Verify the account works on the web
   • Go to www.microsoft365.com and select Sign In.
   • Sign in with the same email and password used in the Office apps.
   • If sign-in fails or shows no subscription, the account may not have a valid Microsoft 365/Office license; use the account that does, or contact the subscription owner/admin.
3. If using mobile apps (Word, Excel, PowerPoint, OneNote, etc.)
   • Open the Microsoft 365 or Office app.
   • On the Recent screen, tap Sign In.
   • Enter the email and password for the account that owns the subscription.
   • If sign-in still fails, follow the mobile guidance:
     • Make sure the correct Microsoft account or work/school account is used.
     • Confirm the username and password work by signing in via a browser as above.
     • Check that the device meets the app’s system requirements.
4. If Office says “no account” but the account is valid
   • Office may be signed in with a different account or cached credentials:
     • Sign out of all accounts inside any Office app.
     • Close all Office apps.
     • Sign back in using only the account that owns the Microsoft 365/Office license.
   • Remember that Microsoft 365 apps do not support being logged in with multiple user accounts from the same organization/tenant at the same time. Log off one account before signing in with another.
5. If sign-in to the Microsoft account itself is failing
   • Use the Microsoft sign-in helper tool to diagnose and fix common account problems: Sign-in helper.

If, after these steps, the account still “does not exist” or shows no subscription, the email being used is almost certainly not the one that owns the Microsoft 365/Office license, or the subscription has expired or been removed by an admin.
