Why Is The Reason Behind This?
Before jumping into the fixes, knowing the root cause is necessary. Understand the possible reasons behind the Outlook.exe Entry Point Not Found Error.
- Broken DLL Files
Outlook is heavily dependent on DLL files like MAPI32.dll to run properly. If these files get wiped out by a virus, a messy software install, or a computer that shuts down mid-update, Outlook loses its roadmap and throws an error.
- A Glitchy Installation
Sometimes, the Outlook installation remains incomplete or interrupted. When this happens, some files or data will be missing. This can happen because of slow internet, storage issues, system crashes, and more. Because of that, Outlook may start successfully, but some important parts are not properly registered, which leads to the Outlook.exe Entry Point Not Found Error
- Faulty or Incompatible Add-ins
Add-ins like Zoom plugin, Grammarly, and CRM tools will increase the functionality of Outlook. It also creates problems sometimes, such as old add-ins not being compatible with Outlook’s new versions, add-ins corrupting the DLL system, and conflicts with multiple add-ins. Open Outlook in Safe mode. Press Win+R, type outlook.exe /safe, and hit Enter. If Outlook opens successfully in Safe Mode, it confirms that a faulty add-in is causing the conflict. You will then need to disable your add-ins one by one to find the specific problem.
- Bloated Data Files
Outlook stores its data in PST and OST files. Large or corrupted PST/OST files can prevent Outlook from opening correctly. While this often leads to loading failures, resolving data corruption is a key step in restoring stability after a system error occurs.”
- Version Mismatches
Outlook must be compatible with your specific versions of Windows and Office. A mismatch, such as using outdated 32-bit components on a newer 64-bit system, often triggers version conflicts and entry point errors. For example, a 32-bit version of Outlook might be installed on a 64-bit Windows system that was recently updated. It’s the same story with Office 2016; DLLs might still be present while Outlook 2019 is trying to use them. Other Microsoft products, such as Teams and OneDrive, are different versions, and Recent Office updates replaced old files. Outlook starts looking for a tool or entry point in a DLL that does not exist in that version, so as a result, an error occurs.
How to Fix the “Outlook.exe Entry Point Not Found” Problem
Method 1: The Classic Restart
Sometimes, the error may be the fallout of temporary system conflicts or background processes.
By refreshing system resources and clearing transient system states, restarting the computer can resolve such issues.
Restarting helps with clearing temporary memory conflicts. Reset the background services. Properly implement any outstanding updates.
Steps:
- Close all applications that you have open.
- Restart your device.
- Attempt to reopen Outlook after the system has resumed.
- Outlook functions routinely if the problem was the result of a temporary system conflict.
Method 2: Open Outlook in Safe Mode.
The application can be launched without the need to install add-ins by operating Outlook in Safe Mode. This assists in determining whether the problem is associated with a third-party extension.
Steps:
- To access the Run dialog box, press the Windows key and the R key.
- Enter the subsequent command:
- exe /safe
- Press the Enter key.
- The conflict may be caused by one of the installed add-ins if Outlook opens successfully in Safe Mode. The issue can be resolved by disabling superfluous add-ins.
Method 3: Repair the Microsoft Office Installation
The necessary components can be restored by repairing the Office installation if the Outlook program files are damaged or absent.
Steps:
