We’ll guide you through the common causes and solutions to keep Outlook running smoothly. Whether it’s a simple setting tweak or a deeper issue, we’ve got the insights you need.

Common Causes of Outlook Closing When Minimized

When troubleshooting Outlook closing upon minimization, we’ll encounter a range of typical triggers that might be causing this behavior. Our expertise and experience point us in the direction of a few suspects known to disrupt Outlook’s proper functioning frequently.

These are the potential reasons for Outlook closes when minimized error on Windows 11/10 or macOS.

  • Incorrect Account Settings
  • Add-ins and Integrations
  • Software Bugs or Updates
  • System Resource Management
  • Power Saving and Sleep Settings

Pro Tip: Here is a quick tip I can provide from my experience. To identify whether the Outlook program is completely closed/terminated on your PC or running in the background when minimized, check the running programs in the Windows task manager. If you find Outlook.exe (or Microsoft Outlook) in active programs/processes, but you are not able to see and open from the normal taskbar, then follow the below solution 1.


Solution 1: Check your Outlook Settings

When tackling the issue of Outlook closing when minimized, one of the first places we’ll want to check is the Outlook settings themselves. Misconfigured settings are often the culprit behind such erratic behavior, and a few adjustments can sometimes set things right.

The first important setting you need to check is its behavior settings in the taskbar when the Outlook program opens on a Windows PC.

  • Open Outlook and right-click on the icon in the System tray. You may need to click the ^ in this section to get this option.
  • Make sure ‘Hide When Minimized’ is not toggled. Otherwise, remove it to fix Outlook closes when minimized issue.


Next, let’s examine the account settings. Incorrect account configurations can lead to various operational issues, including Outlook closing unexpectedly. Under the ‘Account Settings’ tab, let’s verify that all account information is up-to-date and correct. Here’s what we should be on the lookout for:

  • Email address
  • Incoming and outgoing mail server details
  • Usernames and passwords
  • Server timeout settings

Solution 2: Update Your Outlook Software

Updating Outlook is a critical step in ensuring it functions properly. Often, problems like Outlook closing when minimized are addressed in the latest software updates. Microsoft regularly releases patches and updates that not only introduce new features but also fix bugs and improve overall stability.

To update Outlook, we’ll navigate to the File menu and select Office Account or Account. From there, we can access the Update Options dropdown and click on Update Now. This action prompts Outlook to search for and install any available updates. It’s important to ensure that we are connected to the internet during this process for it to be completed successfully.

Solution 3: Disable Third-Party Add-Ins

Sometimes, the culprit behind automatic Outlook closes when minimized is third-party add-ins. These extensions can offer additional features, but they can also cause conflicts or instability in Outlook, leading to unexpected closures. To check if add-ins are to blame, we’ll need to disable them and see if the problem persists.

To disable add-ins, follow these steps:

  • Open Outlook and click on the ‘File’ menu.
  • Select ‘Options’ and then choose ‘Add-ins’ in the left pane.
  • At the bottom of the window, make sure ‘COM Add-ins’ is selected in the ‘Manage’ box and click ‘Go’.
  • Clear all the checkboxes next to the add-ins to disable them.
  • Click ‘OK’ and restart Outlook to test if the issue has been resolved.


If Outlook runs smoothly with the add-ins turned off, it’s likely one of them was causing Outlook to close when minimized. We can then enable add-ins one by one to pinpoint the exact one responsible. Once identified, we have the choice to either update the faulty add-in, if an update is available or remove it permanently to prevent further issues.

It’s essential to keep a note of the add-ins previously installed. Here’s a list of common third-party add-ins that we might encounter:

  • Antivirus add-ins
  • Productivity tools
  • Social media integration add-ins
  • Calendar synchronization tools

Keep in mind that after troubleshooting with add-ins, it’s prudent to conduct regular checks for updates or patches from the add-in developers. This practice will make sure that the add-ins we use are always up-to-date and compatible with the latest version of Outlook, thus minimizing any potential conflicts.

Solution 4: Run Outlook in Safe Mode

Sometimes, running Outlook in safe mode can help us identify if the problem is inherent to Outlook or caused by external factors like add-ins or custom settings. When we start Outlook in safe mode, it launches with limited features, which can often bypass problems that cause the application to close unexpectedly.

To start Outlook in safe mode, simply follow these steps:

  • Close Outlook if it’s currently open.
  • Press the Windows key and type “Outlook.exe /safe” (without quotes).
  • Hit Enter, and Outlook will start in safe mode.

Running in safe mode allows Outlook to operate without the interference of custom toolbar settings, command-line switches, or certain extensions that can often be the culprits behind stability issues if Outlook remains stable while in safe mode, we know that we need to look at external elements rather than the core application itself.

When we have confirmed that Outlook runs smoothly in safe mode, we must determine which component is causing the trouble during normal operation. This troubleshooting step can be tedious, as it involves reactivating add-ins and settings one at a time and testing Outlook after each change. Remember, patience here is key; this methodical approach ensures we don’t miss out on what’s specifically triggering our issue.

Conclusion: Outlook Closes When Minimized in Windows

We’ve covered the vital steps to troubleshoot Outlook closing when minimized, emphasizing the significance of running it in safe mode. This process isolates the problem, pointing us toward a solution without external interference. It’s a strategic approach that often precludes the need for professional help.

Remember, keeping Outlook updated is not just about new features; it’s about maintaining stability and security. By methodically re-enabling add-ins and settings, we can pinpoint the culprit and restore Outlook’s functionality. We’re confident that with these tips, you’ll have Outlook running smoothly again in no time.
