Dear @Jackie Dyer,
Thank you for reaching out to the Microsoft 365 Q&A forum community. I understand this is incredibly frustrating and urgent, especially since you were using the new Outlook successfully just recently. It's worrying to suddenly be locked out.
As part of the Microsoft 365 Q&A forum community support team, we operate strictly through text-based communication on this platform. We do not have the ability to initiate phone calls or offer remote desktop support directly.
To ensure your issue is resolved as quickly as possible, I will provide the steps for you to connect directly with the Microsoft Support team that can offer live assistance and remote support.
Since you are sure you have the correct password, the issue is likely related to the account setup, application corruption, or a temporary synchronization problem. Please try these two common fixes first:
Step 1: Try logging in via Outlook on the Web (OWA)
This step will confirm if the issue is with the Outlook application on your desktop or with your user account itself.
- Open your web browser (Chrome, Edge, etc.) and go outlook.office365.com
- Try to log in using your email address and password.
- If you can log in to the web: This means your account is fine, and the problem is with the New Outlook desktop application. Proceed to Step 2.
- If you cannot log in to the web: The issue is with your account (e.g., password change pending, account locked). You will need to contact your IT Administrator within your company for account recovery, as they manage your company credentials.
Step 2: Reset the new Outlook application data
If you could log in via the web (meaning the desktop app is the issue), resetting the app may clear any corrupted sign-in data.
- Close the New Outlook application completely.
- Go to your Windows Start menu
- Type Apps and select Installed apps from the results.
- Find "Outlook (New)" or "Microsoft Outlook" in the list of applications.
- Scroll down and click the Reset button.
Note: This action will reset the application settings but will not delete your emails or data, as they are safely stored on the cloud. You will just need to sign in again after the reset.
For detailed guidance step by step, please refer to Microsoft’s official documentation: Repair an Office application - Microsoft Support
If the steps above do not work and you still need immediate one-on-one help, you must contact Microsoft's dedicated Business Support team, as they handle company (Work/School) accounts and licenses.
The fastest way to connect for a callback or remote session is to use the Microsoft 365 Admin Center. Since you are an end-user, you may need to ask your IT Administrator to initiate this request for you:
Your IT Admin should: Log in to the Microsoft 365 Admin Center > Go to Support > New service request. This process allows Microsoft support engineers to call you or arrange a remote session.
Please try the two troubleshooting steps first. If they fail, contact your company's IT team immediately to request a support ticket with Microsoft Business Support. We are here to guide you through the process!
