Sometimes, double-clicking on the application shortcut icon does absolutely nothing for you, and you encounter various error messages instead. In this article, you will know the answer to your query: how do I fix Outlook not opening issue.
Reasons Behind Outlook Not Opening Issue
The reasons that prevent your Outlook app from opening are
- It might because of your corrupt/broken local AppData and .pst files.
- The Outlook application or your Outlook account might need fixing,
- A particular problematic add-in might be preventing your Outlook from launching,
- Your PC might have issues running in compatibility mode, etc.
Method 1: Kill MS Outlook Task
There might be a simple answer to how do I fix Outlook not opening question. Before moving forward with specific solutions, let us make sure that an instance of Outlook is not already active in the background. If it is, simply terminate it and check whether this solves the problem or not.

Method 2: Start Outlook in Safe Mode & Disable Add-Ins
Microsoft allows users to expand Outlook functionality by installing a number of useful add-ins. These add-ins work in a similar way to extensions on a web browser and complement the already incredible user experience. Although, sometimes these very add-ins can result in the downfall of the app itself. An outdated or corrupt add-in can prompt a number of issues including Outlook won’t open issue in Windows 10.
Although, before you go on an add-in uninstallation spree, let us confirm that one of them is indeed the culprit. This can be done by launching Outlook in Safe Mode, a mode in which no add-ins are loaded, the reading pane is disabled and custom toolbar settings are not applied. Here’s how to do so:
1. Press the Windows key + R keys simultaneously to open Run dialog box.
2. Type outlook.exe /safe and hit Enter key to launch Outlook in Safe Mode.
3. A pop-up requesting you to choose a profile will appear. Open the drop-down list and choose the Outlook option and hit the Enter key.
Note: Some users may not be able to launch Outlook in safe mode using the above method. In this case, read our guide on How to Start Outlook in Safe Mode.
If you were successful in launching Outlook in safe mode, rest assured that the problem indeed lies with one of the add-ins. Hence, uninstall or disable these as follows:
4. Launch Outlook from the Windows search bar as illustrated below.
5. Click on File tab as shown.
6. Select Options as highlighted below.
7. Go to Add-ins tab in the left and then click on GO… button next to Manage: COM Add-ins, as shown.
8A. Here, click on the Remove button to remove the desired Add-ins.
8B. Or, check the box for Desired Add-in and click OK to disable it.

Method 3: Run Program Compatibility Troubleshooter
The Outlook application is primarily made to run on Microsoft Windows 10, and optimized accordingly.

1. Open the Run dialog box as earlier.
2. Type %localappdata% and hit Enter to open the required folder.
Note: Alternately, follow the folder path C:\Users\username\AppData\Local in File Explorer.
