Outlook Meeting RSVP ‘Tentative’ Default Behavior: How to Change

When you receive a meeting invitation in Outlook, the default response is often set to Tentative. This can be frustrating if you prefer to accept or decline meetings directly without an intermediate status. The Tentative default behavior is controlled by a specific Outlook setting that many users overlook. This article explains why Outlook defaults to Tentative and shows you how to change it to Accept or any other option you prefer.

Why Outlook Defaults to Tentative for Meeting RSVPs

Outlook sets Tentative as the default RSVP response because it assumes you want to review the meeting details before committing. This behavior is built into the Calendar options and applies to all new meeting invitations you receive. The Tentative status places the meeting on your calendar with a striped appearance, indicating you have not fully accepted it.

The default applies when you double-click a meeting invitation in your Inbox or click the meeting in the reading pane. If you do not change the default, Outlook automatically sends a Tentative response to the meeting organizer. This can lead to confusion if you intended to accept immediately.

The setting is stored in the Calendar section of Outlook Options. It is a global setting that affects all meeting requests across all email accounts configured in your Outlook profile. Changing it to Accept or Decline applies to every future meeting invitation you receive.

Steps to Change the Default RSVP Response in Outlook

1. Open Outlook Options
   Click File in the top-left corner of the Outlook window. In the backstage view, click Options at the bottom of the left navigation pane.
2. Navigate to Calendar settings
   In the Outlook Options dialog, click Calendar in the left sidebar. This section contains all settings related to meetings, reminders, and scheduling.
3. Locate the meeting response setting
   Scroll down to the Meeting requests section. Look for the option labeled Default response to meeting requests. The current value is shown in a dropdown menu.
4. Change the default response
   Click the dropdown arrow next to the current setting. Select one of the following options: Accept to automatically send an Accept response, Decline to automatically send a Decline response, or Prompt to show a dialog asking you to choose each time. Selecting Prompt gives you full control over every RSVP.
5. Save the change
   Click OK at the bottom of the Outlook Options dialog. The new default applies immediately to all future meeting invitations you receive. No restart is required.

Alternative Method: Change Default Using the Reading Pane

You can also change the default response directly from a meeting invitation in the reading pane, but this only affects the current meeting, not the global default. To change the global default, you must use the Options dialog as described above.

What Happens After Changing the Default

Once you set the default to Accept, Outlook will automatically send an Accept response and add the meeting to your calendar without any confirmation dialog. If you set it to Decline, Outlook sends a Decline response and does not add the meeting. If you select Prompt, a dialog appears each time you open a meeting invitation, asking you to choose Accept, Tentative, or Decline before sending the response.

Common Issues After Changing the Default RSVP Behavior

Outlook Still Shows Tentative After Changing the Default

If you changed the default to Accept but Outlook still sends Tentative responses, check whether you have multiple Outlook profiles or accounts. The setting applies per profile. Open the correct profile by going to File > Account Settings > Manage Profiles. Also verify that you clicked OK after changing the setting — closing the dialog without clicking OK discards the change.

Meeting Organizer Receives Wrong Response

If the organizer receives a response you did not intend, it is likely because you clicked the meeting invitation in the reading pane without changing the default. The reading pane uses the global default. To avoid this, set the default to Prompt so you must manually select a response each time. Alternatively, use the shortcut keys: Ctrl+R to accept, Ctrl+T for tentative, or Ctrl+D to decline.

Change Does Not Apply to Existing Meetings

The default response setting only applies to new meeting invitations you receive after the change. Existing meetings on your calendar retain their original response status. To change the response for an existing meeting, open the meeting from your calendar, click the Respond button in the ribbon, and select Accept, Tentative, or Decline.

Default RSVP Response Options Compared

Item	Accept	Tentative	Decline
Calendar appearance	Solid color	Striped	Not added
Response sent to organizer	Accept	Tentative	Decline
Time on calendar	Busy	Tentative	Free
Default behavior	User must change default	Out-of-box default	User must change default

The table shows how each RSVP option affects your calendar and the organizer. Changing the default to Accept or Decline can save time if you consistently respond the same way to most meetings. The Prompt option gives you maximum control without changing the global default.

You can now change the default RSVP response in Outlook to match your workflow. Try setting it to Prompt if you want to choose a response for each meeting individually. For advanced control, use the keyboard shortcuts Ctrl+R for Accept, Ctrl+T for Tentative, and Ctrl+D for Decline to respond without opening the full meeting form.
