The Output path is stored in the .cproj file. One for each configuration.
Open ur *project_Name.csproj* in any editor (say notepad)
For Debug:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' ">
.....
<OutputPath>myOutput\</OutputPath>
</PropertyGroup>
Similarly For Release:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
...
<OutputPath>bin\Release\</OutputPath>
</PropertyGroup>
You could try manually editing the OutputPath.
The Output Path can take both Relative and Absolute paths.
Note: The Relative OutputPath should be relative to your project directory (project_Name.csproj) .
