Outlook Online and Android Phone App Not Saving Settings

Hi @Vernon, Isabelle M, 

I appreciate you reaching out regarding the issue where Copilot settings in Outlook Online and the Android app fail to save, resulting in the feature re-enabling itself daily. 

Based on my testing environment and reports from other users, Copilot may automatically reappear in Outlook after a short period, even after it has been manually disabled. I am sorry that you have had this experience, as I understand how disruptive it is to have your workflow settings reset unexpectedly. 

In this situation, I recommend providing feedback directly to the Outlook product development team at Microsoft. You can do this by clicking Help > Feedback > Report a problem. Submitting this report is vital because it alerts the engineering team to specific synchronization issues that may not be apparent in standard testing. Your feedback serves as a primary driver for future updates, ensuring that the software respects user-defined configurations and providing the team with the telemetry needed to implement a permanent fix. 

I am truly sorry, as I know this is not the resolution you were hoping for. As a community moderator, the most I can do here is confirm the behavior and explain the technical reasons behind it. Since this is a product-level issue regarding how settings sync across the cloud, I am unable to manually intervene at the service level to force these preferences to stick.

While awaiting a service update, you can try the following workaround to refresh your local data: 

1. Completely close the Outlook application. 
2. Press Windows + R, then enter the following command: olk.exe --devtools 
3. Click on the Application tab. 
4. Under Local Storage and Cookies, right-click on outlook.office.com and select Clear to delete the stored data. 

After completing these steps, please disable Copilot again to see if the setting remains. 

If you have Global Administrator permissions for your tenant, you also have the option to disable Copilot at the tenant level. This is a more definitive method to ensure the feature does not reappear. To do this, go to admin.microsoft.com, select Settings, and then Integrated apps. Under the Available apps tab, search for Copilot and configure the option to disable it for your account. Please allow 24 to 48 hours for the system to process these changes. 

Note: Once this option is applied, you will not be able to use Copilot in any situation unless you re-enable this feature for the corresponding account. If you are not an administrator, you can contact your tenant admin and ask them to assist you with these steps and apply the setting specifically to your account. 

If this information is helpful, please consider marking this response as the "Accepted Answer." This helps other users easily notice the issue and take immediate action by reporting it, which assists in securing a fix and improving Outlook for everyone. 

If you have any updates or need further assistance, please share them with me.

Copilot in Outlook uses different controls depending on the platform, and those controls sync in specific ways.

For Outlook on the web and the new Outlook for Windows, Copilot is controlled by a Turn on Copilot toggle under Settings > Copilot. For Outlook on Android, the same toggle is under Quick Settings > Copilot. As of June 3, 2025, this toggle is available on:

1. Android: Quick Settings > Copilot
2. Web: Settings > Copilot

When Copilot is turned off using this toggle in Outlook, that choice applies to Outlook on all devices where the same account is signed in. For example, turning Copilot off in Outlook on the web should also turn it off in Outlook on Android for that account.

If Copilot keeps turning back on each day, check the following:

1. Make sure the Turn on Copilot toggle is being used in Outlook (web and Android), not just other Microsoft 365 apps like Word or Excel. The Outlook toggle is separate from the Enable Copilot checkbox used in Word, Excel, PowerPoint, and OneNote.
2. Confirm Outlook on Android is updated to the latest version from the app store so the Copilot toggle is available and can sync correctly.
3. Verify that the same account is being used in both Outlook on the web and Outlook on Android; the Copilot setting roams per account.

If the Copilot toggle is not available in Outlook yet, Copilot can be turned off by changing account privacy settings, but this also disables other connected experiences (such as suggested replies in Outlook, text predictions in Word, PowerPoint Designer, and automatic alt text). Details on those features are listed under connected experiences in Office.
