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

This guide walks you through account locked & blocked using Microsoft-supported steps first, with WPS only where it genuinely helps.

Problem Description: No Access Microsoft 365

Hi all, A client of ours isn't able to access the admin level of their Microsoft 365 Admin Center. This is due to the original admin being no longer contactable. How would we go about gaining access to the center so we can add additional emails etc to the account? We have twice tried reaching out to Microsoft Support but they are not responding. We asked if perhaps one of the emails already set up within the account could become an admin - or at least temporarily to gain access, then amend the main admin user within the account. We do not even know the .onmicrosoft.com email address original created to set up the account. Any help, direction would be gratefully received. Many thanks *[Moderator note: personal info removed]*

Quick Answer for Microsoft 365 Setup on New Device

To regain access when the original admin is unavailable, first identify if you're the only global admin.

Likely Causes Behind Account Locked 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• Cached credentials, outdated builds, or damaged local components can trigger account locked & blocked.

• 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 so, contact the Azure Data Protection team at +1 866-807-5850.

2. If other global admins exist, reach out to them.

3. If no global admin exists in your company, contact the Microsoft 365 Data Protection team—find your region's support phone number and request transfer to that team for password reset.

4. If you're not part of the tenant, ask a colleague who is to contact them on your behalf.

5. If Microsoft Support hasn't responded, ensure you're using correct channels and start a service request online.

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.

Prevention Tips for Keeping Microsoft 365 Stable Long Term

• Keep one primary Microsoft account for subscriptions and Office sign-in.

• Install updates for Office and Windows before retrying failed workflows.

• Back up important files before repair, reset, or reinstall actions.

• Register more than one MFA method and keep recovery contacts current.

FAQs About Microsoft 365 Support Questions

Can WPS Office fix this account locked & blocked issue directly? Only when the WPS steps match the formatting or file task. Account, activation, and cloud issues stay on the Microsoft side.

Should I reinstall Microsoft 365 before trying these steps? Not first. Confirm account, license, and the exact error before reinstalling.

What should I send to Microsoft Support? The affected account email, device type, Office version, exact error text, and screenshots with personal data hidden.
