How to Stop Accidentally Closing Outlook

Last reviewed on May 8, 2014   —  23 comments

Note that this method does not work with Microsoft Outlook 2010 pre-SP1. See the Outlook 2010 section below for one solution when using Outlook 2010 SP1 (v 14.0.6023.1000 or higher).

It’s very easy to accidentally close Outlook by clicking on the X in the upper right-hand corner, instead of the minimum button. There are several ways you can prevent this.

Note: If you have Outlook 2003 or above, its possible to set it to minimize to the tray (notification area). Many users don’t realize they enabled this option and think Outlook closed when they minimized it. Look for the Outlook icon in the notification area to verify Outlook is not running minimized.

Unsent method

  1. Open a new message – enter “Keep Outlook Open” as the subject. Don’t enter an address in the To field!
  2. Save the message to Drafts.
  3. Drag it from Drafts to the Outbox.
  4. When you exit Outlook, you’ll have the chance to cancel closing Outlook.

In Outlook 2000 Corp, you’ll need a POP3 account in the profile for this method to work. (It can use fake server names.)

Outlook 2010

The “Unsent Method” mentioned above does not work in Outlook 2010. In fact, in Outlook 2010 RTM (the released version), there is no unsent message warning, even for “real” messages in the Outbox. SP1 restores the warning but it only works if messages are send-able, meaning the Unsent Method above is still useless.

However, you can set Outlook to delay delivery of a message to force the warning and prevent accidental closing. Choose a date in the future in the “Do not deliver before” date field.

Please note, this only works in cached mode. Delayed messages are stored on Exchange server in classic online mode.

To use this method:

  1. Open a new message
  2. Enter your own address in the To field
  3. Enter “Keep Outlook Open” as the subject
  4. Switch to the Options tab
  5. Click the Delay Delivery button and enter a future date (a year or so should be fine.)

OLKeeper reliably prevents users from closing their Outlook and thus possibly missing reminders or e-mails. When you click the X button to close Outlook, OLKeeper asks you what to do: minimize, close or cancel. You will never again miss an important appointment or e-mail just because Outlook was accidentally closed or waste your time with unnecessary, long waits during Outlook restarts. Supports Outlook 2010.

    Hi. you can do it easily in Outook 2007 by selecting the "Hide when minimised" option in the system tray Outlook icon

    2010 has a task bar, and right clicking has different menu, "Hide when minimized" not there.
    When i minimize, outlook closes, it is not hidden. Also within the task bar, you can roll your mouse over an icon for a "preview" again with the outlook icon nothing. Any suggestions?

    Why is there no real option to cancel? This drives me crazy.

    I don't want to seem like a thread hijacker but since it's related, I'd like to ask if anyone knows of a way to exit Outlook (2010) so that any open email/message windows are restored when you start Outlook.

    I'm asking as I usually have 2-3 dozen emails open (work in progress) and it's a real pain to flag each one to followup before exiting, and then opening each one on start.

    Thanks Diane, it is working

    At least once a week I will unintentionally close Outlook, usually after checking calendar, sometimes wrong "X" when closing a message.
    The "delayed send" option didn't seem to work, but minimizing an unsent "Do you really want to close Outlook?" message to self allows me to cancel.

    I have a simpler answer: Don't run Outlook 2007 in full screen mode. Drag the right side of the Outlook window until the Close box goes off the screen. If I can't see it, I can't click it.

    Thanks for the post.... really helpful...

    Bless you Diane. The "Hide when minimized" was the issue that was frustrating me. When I unchecked it, I found I had 8 instances of Outlook running, because I would launch it, thinking I was restoring.

    Hi Diane, I normally keep a lot of emails minimized while Outlook 2010 is openned, to review those emails later. By accident, I closed the Outlook, so all the minimized message were closed too... when I reopen Outlook, how can I get the minimized message back? is there a way to reopen those minimized message? By the way, they were not draft, just regular mode view emails... Thank you and God Bless you!
