This interoperability is essential for automating Outlook processes or integrating Outlook data with other applications.
When you encounter an error with `Microsoft.Office.Interop.Outlook.dll`, it typically indicates a problem with the integration between your application and Outlook. This could be due to the DLL being missing, an incorrect version being referenced in your project, or compatibility issues between the version of Outlook installed and the version targeted by your application.
To resolve issues related to `Microsoft.Office.Interop.Outlook.dll`, ensure that the correct version of the DLL is referenced in your .NET project. This might involve adding the reference through Visual Studio's Reference Manager, potentially targeting the specific version of Outlook you're working with.
