Outlook 2007 / 2010: Accepting meeting request deletes the email

In Microsoft Outlook application we use meeting request to invite people to the meetings. The Receivers of this meeting request can accept or reject the meeting request based on their availability or willingness to attend the meeting. When the user accepts a meeting request, the mail gets deleted from the mailbox / Inbox and would be sent to Deleted Items. In case if the user wants to see the mail again, the user would have to check Deleted Items folder.

We can change this functionality by configuring the settings of Outlook. This can be done as follows. The steps are different based on which version of Outlook you are using.

Outlook 2010:

  • Click on File menu.
  • Click on Options. Click on the Mail tab.
  • Under ‘Send Messages‘ category, disable the check button ‘Delete meeting request and notifications from Inbox after responding‘.

Outlook 2007:

  • Click on Tools in Outlook application.
  • Select Options
  •  Now in the options windows click on E-mail Options button shown in the above window. Now you will see a window like below.
  • Now in this new window you need to click on the button ‘Advanced E-mail Options‘ as shown in the above image.
  • Now in this Advanced E-mail options window, unselect the check button ‘Delete meeting request from Inbox when responding’
  • After making the above changes, meeting request emails will not get deleted even after you accept/reject them.

Registry key :

This meeting request email deletion is controlled by the registry key DeleteWhenRespond. In Outlook 2007, navigate to the  following path.


Under the above key, create a new registry value of type REG_DWORD and name it DeleteWhenRespond.  Set its value to 0.

For Outlook 2010, you need to create the key under the below node.


Closing and reopening Outlook will make the changes effective. It’s OK even if the registry key exists already, just change the value in such case. The key will not exist if you have never modified this setting before.
