Microsoft 365 is a robust suite of services that many organizations rely on for their daily operations. However, users may occasionally encounter error messages that can hinder productivity. One such error is the “Error 70003: Your Organization Has Deleted This Device,” which can occur when trying to access Microsoft 365 services. Here’s how to troubleshoot and resolve this issue

Step 1: Confirm Device Status with Your Administrator

The first step should always be to verify with your organization’s IT administrator that your device hasn’t been intentionally removed from your organization’s network. In some cases, this error could appear if the device has been remotely wiped or unenrolled by an admin.

Step 2: Clear Your Credential Manager

If there’s been no administrative action behind the error, try clearing your Credential Manager:

– Press `Windows Key + R`, type `control panel` and hit `Enter`.

– Navigate to `User Accounts > Credential Manager > Manage Windows Credentials`.

– Remove any credentials related to Microsoft Office or Microsoft 365.

Step 3: Reset Office Activation State

Sometimes the error might be a result of issues with the activation state of Office:

– Close all Office applications.

– Open Command Prompt as an administrator.

– Type `cd %programfiles(x86)%\Microsoft Office\Office16` or `cd %programfiles%\Microsoft Office\Office16` depending on your installation.

– Run `cscript ospp.vbs /rearm` and then restart your device.

Step 4: Reconnect Your Work Account

Re-add your work account to Windows in case it has been incorrectly removed:

– Go to `Settings > Accounts > Access work or school`.

– Disconnect any existing work-related accounts.

– Connect again using your work account credentials.

Step 5: Repair Office Installation

A repair might solve the issue if it’s related to the installation files:

– Go into the Control Panel and select `Programs and Features`.

– Find your Microsoft Office installation in the list.

– Click on it and choose ‘Change’ from the top menu, then follow prompts for a Quick Repair.

Step 6: Reinstall Microsoft 365

As a last resort, if none of the above steps work, you might need to reinstall Microsoft 365:

– Uninstall the current installation via the Control Panel.

– Reinstall from the official website by logging into your account and following installation prompts.

Always remember to back up any important data before making changes to software installations or settings. If you continue to experience issues after following these steps, contacting Microsoft Support for further assistance would be advisable.
