How to fix Outlook if it won’t open in Windows 10
If you’re having trouble getting Outlook to open on your Windows 10 computer, there are a few things you can try to fix the issue. First, make sure that your computer meets the system requirements for Outlook. Then, try opening Outlook in Safe Mode, which will disable any add-ins that could be causing the problem. If that doesn’t work, you can try resetting Outlook to its default settings. Finally, if none of these solutions work, you may need to reinstall Outlook.
1 Start Outlook 2016 in Safe Mode and Disable Add-ons
Assuming that you are using Microsoft Outlook 2016, there are a few things that you can try if you find that Outlook won’t open in Windows 10. Firstly, you can try starting Outlook in Safe Mode. To do this, simply press and hold the CTRL key while you click on the Outlook shortcut. This will bring up a dialog box asking if you want to start Outlook in Safe Mode. Simply click on the Yes button and Outlook should start in Safe Mode.
If Outlook starts in Safe Mode, then the problem is most likely due to an add-in that is causing issues. To disable add-ins, simply go to the File menu and click on Options. This will bring up the Outlook Options dialog box. Click on the Add-ins tab and then click on the Go button. This will bring up the Manage COM Add-ins dialog box. Simply uncheck the box next to the add-in that you want to disable and then click on the OK button.
If Outlook still won’t open, then the next thing to try is to repair your Outlook profile. To do this, simply go to the Control Panel and click on Mail. This will bring up the Mail Setup dialog box. Click on the Show Profiles button and this will bring up the Outlook Profile Manager. Simply select the profile that you want to repair and click on the Remove button. You will then be prompted to create a new profile. Simply follow the prompts and once the profile has been created, try opening Outlook again.

If Outlook still won’t open, you can create a new profile and see if that fixes the problem. To do this, go to the Control Panel and then click on Mail.
In the Mail setup window, click on Show Profiles. This will bring up a list of all the profiles currently on your computer.
Click on Add and then enter a name for the new profile. Once you’ve done this, click on OK.
Now you’ll need to add your account information to the new profile. To do this, click on the new profile and then click on Properties.
Enter your name, email address, and password. Once you’ve entered this information, click on OK.
Now try opening Outlook. If it still doesn’t work, you can try repeating these steps with a different profile name.

If you’re still having trouble opening Outlook, try checking your dialog boxes. Dialog boxes are small windows that pop up to request information from you or give you messages.
