Copilot in Outlook mobile depends on the signed-in account, an eligible Copilot license, a supported app build, and access to Microsoft services. Check those dependencies in that order so you can distinguish an account entitlement problem from a temporary app or network issue.
7 Ways to Fix Copilot Not Working in Outlook on a Phone
1. Refreshing the Microsoft 365 Copilot License
- The most common reason for this issue is an expired or desynced Copilot Pro or Enterprise license on the mobile app.
- Sign out of the Outlook app, verify the active subscription on the Microsoft account web page, and sign back in to refresh authorization tokens.
- Solves the root authorization issue immediately without losing local settings.
- Requires remembering account credentials and navigating to a web browser.
2. Updating the Mobile Outlook Application
- Microsoft frequently patches Copilot integration bugs in regular app updates.
- Navigate to the App Store (iOS) or Google Play Store (Android), search for Outlook, and tap Update.
- Fast, safe, and often resolves background API connection errors.
- Requires a stable internet connection and sufficient device storage.
3. Enabling "Connected Experiences" in Privacy Settings
- Copilot relies on cloud-based AI processing, which is completely blocked if optional connected experiences are disabled.
- Open Outlook Settings > Privacy Settings > toggle on "Turn on experiences that analyze your content."
- Fixes a hidden setting that many enterprise users have turned off by default.
- Requires sharing email content data with Microsoft's cloud services.
4. Clearing the Outlook App Cache (Android Only)
- Corrupted temporary data can prevent the AI add-in from loading in the compose window.
- Go to Phone Settings > Apps > Outlook > Storage > Clear Cache.
- Does not delete emails or require signing back in.
- Not available natively for iOS users.
5. Resetting the Account within the Outlook App
- Forces the app to rebuild the folder hierarchy and refresh add-ins without a full software reinstall.
- Tap the profile icon > Settings > select the email account > tap "Reset Account".
- Restores synchronization for Copilot features quickly.
- The app will restart and take a few minutes to download recent emails.
6. Switching Default Email Address to a Microsoft Domain
- Copilot often fails to trigger if a third-party IMAP/Gmail account is set as the primary drafting address.
- Change the "From" address in the email compose window to an @outlook.com or authorized enterprise domain.
- Bypasses compatibility limitations with third-party email providers.
- Restricts the user to specific email addresses for AI drafting.
7. Reinstalling the Outlook App
- The practical fallback when all other methods fail to initialize the AI modules.
- Uninstall the app completely, restart the phone, and download it fresh from the app store.
- Clears all deep-seated bugs and corrupted authentication tokens.
- Time-consuming and requires setting up all preferences and signatures again.
