Copilot Not Working in Outlook on Windows: How to Fix It

Microsoft Copilot in Outlook is designed to help users draft emails, summarize conversations, and improve productivity. However, in some cases, Copilot may not appear or may stop working entirely in Outlook on Windows.

This guide explains the most common reasons why Copilot is not working in Outlook and how to fix the issue step by step.

Check If Copilot Is Supported in Your Outlook Version

Copilot does not work in all Outlook versions.

Copilot is supported only in:

• Microsoft Outlook for Microsoft 365
• Outlook with a Copilot-enabled Microsoft account
• Work or school accounts with Copilot access

Copilot is not available in:

• Outlook 2016 or older
• Standalone Outlook licenses without Microsoft 365
• Free Outlook accounts

Make sure you are signed in with the correct account.

Ensure You Have an Active Copilot Subscription

Copilot requires an active subscription.

Check the following:

• You are signed in to a Microsoft 365 account
• Copilot is enabled for your account or organization
• Your subscription has not expired

If you are using a work or school account, Copilot availability depends on your organization’s license.

Update Outlook to the Latest Version

An outdated Outlook version can prevent Copilot from loading.

Steps to update Outlook:

1. Open Outlook
2. Click File
3. Go to Office Account
4. Click Update Options
5. Select Update Now

Restart Outlook after the update completes.

Enable Copilot from Outlook Settings

In some cases, Copilot is disabled in settings.

Steps to check:

1. Open Outlook
2. Click File
3. Go to Options
4. Select General
5. Look for Copilot or AI features
6. Enable the option if available

Restart Outlook and check again.

Check Internet Connection and Microsoft Services

Copilot relies on cloud services.

Make sure:

• Your internet connection is stable
• You are not using a restrictive VPN
• Microsoft services are not experiencing outages

If Copilot works intermittently, network restrictions may be the cause.

Disable Conflicting Outlook Add-ins

Some add-ins can interfere with Copilot.

Steps to disable add-ins:

1. Open Outlook
2. Go to File
3. Click Options
4. Select Add-ins
5. Disable non-essential add-ins
6. Restart Outlook

Re-enable add-ins one by one to find the conflicting one.

Sign Out and Sign Back Into Outlook

Account sync issues can prevent Copilot from loading.

Steps:

1. Open Outlook
2. Go to File
3. Click Account Settings
4. Sign out of your account
5. Restart Outlook
6. Sign in again

This refreshes Copilot and Microsoft 365 services.

Repair Microsoft Office Installation

If Copilot still does not work, repair Office.

Steps:

1. Open Settings
2. Go to Apps
3. Select Installed apps
4. Find Microsoft 365
5. Click Modify
6. Choose Quick Repair

Final Thoughts

Copilot not working in Outlook is usually caused by account limitations, outdated software, or disabled features. In most cases, updating Outlook, checking subscription status, or repairing Microsoft 365 resolves the issue.
