Why Microsoft 365 Keeps Access Microsoft 365 and How to Fix It

This guide walks you through mfa & verification issues using Microsoft-supported steps first, with WPS only where it genuinely helps.

Problem Description: Unable Access Microsoft 365

I recently changed my phone and lost access to the Microsoft Authenticator app associated with my Microsoft 365 admin account. The authenticator was installed on my previous device and I no longer have access to it. I’m unable to recover it and cannot complete the sign-in process. Additionally, when I try to contact support, the system requires me to sign in, which I’m unable to do due to this issue. I need assistance regaining access to my admin account.

Quick Answer for Microsoft 365 Setup on New Device

If you lost access to Microsoft Authenticator and cannot sign in to your Microsoft 365 admin account, contact Microsoft support by calling the hotline and indicating you are a business email user needing technical support.

Likely Causes Behind MFA Root Factors

• The Microsoft account or license context may not match the purchase or device.

• Cached credentials, outdated builds, or damaged local components can trigger mfa & verification issues.

• A file-specific corruption or add-in conflict can mimic a broader application failure.

Recommended Solution: Repairing Microsoft 365 Startup Issues

When to use this: Apply these steps when the symptoms match and you can access the relevant Microsoft account or administrator.

1. If other administrators exist, ask them to reset your Multi-Factor Authentication (MFA) settings via the admin portal.

2. As a workaround, create a trial Microsoft 365 tenant to access the Admin Center and submit a support ticket to the Data Protection team for your previous tenant, then escalate the issue if needed.

Alternative Solutions for Secondary Login Fixes

1. Retry the Microsoft-side steps after restarting the app and device.

2. Test the same action in a private browser session or a new blank file to isolate account vs file issues.

3. Capture exact error text and screenshots before contacting Microsoft Support or your administrator.

Working with WPS Office: WPS as a Local Alternative

WPS Office cannot replace Microsoft account, activation, or cloud fixes for this scenario. It remains one of the best free Microsoft Office-compatible alternatives for opening and editing local files.

1. Download and install WPS Office from the official website.

2. Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.

3. Save a working copy locally while Microsoft-side issues are resolved.

4. Return to Microsoft Office after the primary fix succeeds.

If you need a practical local workspace in the meantime, try WPS Office.
