Step 2- Choose Processes Tab:

After opening your Task Manager window, you need to select the Processes tab which is generally the second tab at the left top side of the window.

Step 3- Close Invisible Background Procedures:

Now it’s time to close all the unwanted invisible background procedures which are left run by your Outlook and causing it not to open.

Step 4- Outlook.Exe:

Find out the process with the name “Outlook.Exe.”

Step 5- Click on the Process:

When you find out that process with the name “Outlook.Exe”, click on that immediately.

Step 6- End Process:

After that, just click on the “end process” button located at the right bottom side of your Task Manager.

Always repeat from step 3 to step 6 when the outlook is left running on your device. It’s also recommended to check the list of all the programs that your Outlook is running.

Step 7- Warning:

You may see a warning box stating something like “terminating a process can cause undesired results including loss of data and system instability.” Do not worry. This is normal and has nothing to do with your system. So just press the Yes button and continue.
