office 365 login issue

Question

Office 365 was shared with me and I installed it but it won't let me login. I have been trying for two days.

Answer 1

If you're having trouble logging into Office 365, there could be several reasons for this issue. Here are some common causes and resolutions:

1. Incorrect Username: Make sure you are using the correct Office 365 user ID, which is typically your user principal name (UPN), such as ******@contoso.com.
2. Expired Password: Check if your password has expired. If it has, you will need to reset it.
3. Account Activation: Ensure that your Office 365 user account is activated. If it is not, you may need to follow the activation process.
4. Blocked Account: If your Microsoft account is blocked, wait for about 15 minutes and try logging in again. If the issue persists, consider resetting your password to unblock your account.

If you continue to experience issues, you may want to run the Microsoft 365 sign-in troubleshooter or check your security software settings, as they can sometimes interfere with the sign-in process.

Hello, thank you for reaching out to Microsoft Q&A.

May I please know the exact error message you receive when you try to sign in with your Microsoft account in the Office 365 applications?

Also, do you see the Office 365 subscription that was shared with you listed under the Services & Subscriptions section of your Microsoft account?
