How to Disable Copilot Automatic Scheduling Suggestions

When you compose an email in Outlook, Copilot may automatically suggest meeting times and scheduling options based on the content of your message. This feature is designed to help you arrange meetings faster, but some users find these suggestions distracting or unnecessary. The suggestions appear as a small calendar icon or a pop-up prompt while you are typing. This article explains how to turn off Copilot automatic scheduling suggestions in Outlook for Microsoft 365.

The automatic scheduling suggestions come from the Copilot integration in Outlook that analyzes email text for dates, times, and meeting requests. When enabled, Outlook scans your message for phrases like “let’s meet” or “next Tuesday” and offers to insert a proposed meeting time or a scheduling poll. Disabling this feature removes these prompts entirely without affecting other Copilot capabilities such as draft assistance or email summarization.

You can disable the scheduling suggestions in two ways: through the Outlook Options menu or via the Copilot settings pane. Both methods produce the same result. Choose the one that fits your workflow.

Why Copilot Shows Scheduling Suggestions While You Type

Copilot in Outlook uses natural language processing to detect meeting-related language in your email body. When it identifies a potential meeting request, it displays a small pop-up or an icon near the compose window. Clicking the icon opens a panel where you can select a suggested time or create a scheduling poll. This feature is part of the Microsoft 365 Copilot subscription and is enabled by default for users with a Copilot license.

The scheduling suggestions rely on two components: the built-in AutoCorrect actions list and the Copilot settings service. The AutoCorrect actions list contains predefined triggers for meeting-related phrases. The Copilot settings service controls whether the suggestions appear at all. Disabling either component stops the prompts.

Steps to Disable Copilot Scheduling Suggestions via Outlook Options

This method removes the scheduling action from the AutoCorrect list. It is the most direct way to stop the prompts without affecting other Copilot features.

1. Open Outlook and go to File > Options
   In the Outlook window, click the File tab in the top-left corner. Then click Options at the bottom of the left pane. This opens the Outlook Options dialog box.
2. Select Mail and then click Editor Options
   In the Outlook Options dialog, click Mail in the left column. Scroll down to the Compose messages section and click the Editor Options button. A new dialog titled Editor Options opens.
3. Open AutoCorrect Options and go to the Actions tab
   In the Editor Options dialog, click Proofing in the left column. Then click the AutoCorrect Options button. In the AutoCorrect dialog, click the Actions tab at the top.
4. Uncheck Enable additional actions and remove the scheduling action
   In the Actions tab, uncheck the box labeled Enable additional actions in the right-click menu. Below that, in the list of available actions, find Scheduling suggestions or Meeting scheduling. Click it and then click Remove. Click OK to close each dialog.
5. Restart Outlook
   Close Outlook completely and reopen it. The scheduling suggestions should no longer appear while you compose emails.

Steps to Disable Copilot Scheduling Suggestions via the Copilot Settings Pane

This method uses the Copilot sidebar in Outlook. It is faster if you already have the Copilot pane open.

1. Open a new email or reply in Outlook
   Click New Email or reply to an existing message. This opens the compose window where Copilot suggestions appear.
2. Open the Copilot pane
   In the ribbon at the top of the compose window, click the Copilot icon. It looks like a purple or blue sparkle. The Copilot pane opens on the right side of the screen.
3. Click Settings in the Copilot pane
   At the bottom of the Copilot pane, click the Settings gear icon. A list of toggles appears.
4. Turn off Show scheduling suggestions while composing
   Find the toggle labeled Show scheduling suggestions while composing. Click it to set it to Off. The change saves automatically.
5. Restart Outlook
   Close Outlook and reopen it to ensure the setting is applied. The scheduling prompts will no longer appear.

Common Issues After Disabling Scheduling Suggestions

Copilot Scheduling Suggestions Still Appear After Disabling

If suggestions continue to appear, the AutoCorrect actions list may still contain the scheduling action. Repeat the steps in the first method and verify that the scheduling action is removed from the list. Also check that the Copilot settings pane shows the toggle as Off. If both settings are correct, sign out of your Microsoft 365 account and sign back in.

Other Copilot Features Stop Working After Disabling Scheduling Suggestions

Disabling scheduling suggestions does not turn off other Copilot features such as draft assistance, email summarization, or meeting recap. Only the scheduling prompts are affected. If other Copilot features stop working, the issue is unrelated. Check your Copilot license status or contact your IT administrator.

Cannot Find the Scheduling Suggestions Option in the AutoCorrect List

If the Actions tab does not list Scheduling suggestions, the feature may not be installed or enabled for your account. This can happen if you do not have a Copilot license or if your organization has disabled the feature. Confirm with your IT administrator that Copilot for Microsoft 365 is active. You can still use the Copilot settings pane method to disable the prompts.

Item	Outlook Options Method	Copilot Settings Pane Method
Steps required	Five steps through File > Options	Five steps through the Copilot sidebar
Permanence	Removes the action from AutoCorrect permanently	Toggle is saved per user account
Affects other Copilot features	No	No
Works without Copilot license	No, requires Copilot for the action to exist	No, the pane requires Copilot
Requires restart	Yes	Yes

You can now disable Copilot automatic scheduling suggestions in Outlook using either the Outlook Options method or the Copilot settings pane. Both approaches stop the pop-up prompts without affecting other Copilot features. If you later want to re-enable the suggestions, follow the same steps and turn the setting back on. For users who need more control over meeting scheduling, try using the built-in Scheduling Assistant instead of relying on Copilot prompts.
