Step 1: Reasons for ‘Outlook does not close’ issue

It can happen due to different reasons. Here are some:

• The primary cause is third-party add-ins and plug-ins installed in Outlook.
• Outlook is still running in Task manager with the name Outlook.exe
• It might be caused by programs that are integrated or connected to Outlook. Some of these might be Skype, anti-virus scanners and synchronization software like iTunes and ActiveSync.
• In some cases, the sidebar gadgets of Windows 7 and Vista might also cause the issue because they can display Outlook information.

Step 2: What should you do to get rid of “Outlook does not close” error?

There are various ways to solve this issue and here are some top solutions that will help you.

Solution 1: Try to terminate Outlook with task manager
If your Outlook application is still running even after closing it multiple times, the Windows Task Manager can help. Using the Task Manager is very easy; it is the system app shows you the applications running on your PC. So here is how you can use Task Manager to shut down Microsoft Outlook.

1. Press “Ctrl + Shift + Esc” or “Alt + Ctrl + Del” on your keyboard so that the Task Manager will show up.
2. Click the “Details” tab.
3. Look for the “Outlook.exe” in the list of applications, and click it.
4. Click “End Process”

You will be prompted by your computer if you really want to close the application, so just click “End Process” in the dialog box.

Step 3: Disable Outlook Add-ins

If Outlook is not closing even after multiple attempts, unnecessary third-party plug-ins need to be disabled. You can disable them by following the below-mentioned steps.

For Outlook 2010, 2013 and Outlook2016 users:
• Open your PC’s Microsoft Outlook and click “File”
• Click “Options”
• Once the Outlook Options window is opened, go to “Add-ins” and click “Go”
• You will see the different add-ins that are hooked in your Microsoft Outlook application. Uncheck all of the boxes of the add-ins. Press “OK” to disable them.

For Outlook 2007 users:
• Open Outlook and go to Tools.
• Navigate to ‘Trust Center’.
• Then click on ‘add-ins’ and select add in to disable.

For Outlook 2003 users:
• Click on ‘Tools’ and head towards ‘options.’
• Later scroll towards tab ‘Other’ and then click the button ‘Advanced Options’.
• Finally, click on the button ‘Add-in Manager’ or the button ‘COM Add-ins’.
• Disable the add-ins.

If your Microsoft Outlook worked perfectly after doing this method, then the problem was due to one of the add-ins. To know which one of them is causing the issue, try enabling the add-ins one by one and restart the Outlook application after every change.

Step 4: Close the interrupting programs

If you have installed programs such as synchronization software or such other communication programs, then there is a chance that these programs might be the reason Outlook is not closing. Several programs that are associated with Microsoft Outlook are often not available in the Add-ins list.
Therefore, any program that is interrupting the operation of Microsoft Outlook, needs to be disabled. Close the programs such as Skype, ActiveSync, iTunes, Antivirus and then check if the Outlook closes. Also disconnecting the USB devices from your computer might help. Once the issue is fixed you can enable them again.

Step 5: Scanning the Data File

Whenever Microsoft Outlook faces termination issues, there is a chance that your data files (PST and OST) might have got corrupted. So, scan the PST file using Microsoft’s default inbuilt Inbox repair tool to prevent future problems. You can do it by following the below steps:

• You need to close Outlook first.
• Check that it is not running in Task manager. If yes, end the process
from Task Manager.
• Then go to Start and click on Search.
• Type scanpst.exe
• Double click on the exe and run it.
• It will start scanning and report if any errors are found.
• Click Repair if any issues are found.

Step 6: Use automated software to repair PST file
