Microsoft Account Email Hacked Last Night Error: Step-by-Step Fixes

When Office stops working as expected, start with the shortest official checks before you reinstall anything.

Problem Description: Email Hacked Last Night

My Microsoft account was hacked, I regained access, they changed passwords for everything, it now looks like I’m sending spam emails and other emails some have sent some are undelivered, how do I stop this ?

Quick Answer for Office Setup on New Device

Immediately disable your compromised account using the Microsoft Graph PowerShell module to halt all unauthorized activity and prevent further data exfiltration.

Likely Causes Behind Account Security Problems 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• Cached credentials, outdated builds, or damaged local components can trigger account security problems.

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

Recommended Solution: Transferring Office License Safely

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

1. Change your password to a strong, unique credential and strictly avoid transmitting the new password via email, as attackers may still monitor your mailbox.

2. Use PowerShell commands to audit and remove any suspicious inbox rules designed to forward messages or automate spam distribution.

3. Thoroughly inspect your Sent Items folder to document unauthorized outgoing communications, and collaborate with your IT administrator to remove your account from any restricted entity lists, thereby restoring normal sending capabilities and securing your environment.

Alternative Solutions for Secondary Security 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 Office 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.

• Review connected devices and sign-in activity regularly.
