includepath with network folders

I have a C++ workspace with following folder hierarchy

myWorkspace/
myWorkspace/component1/ImportedInterfaces/*.h --> need to exclude this folder
myWorkspace/component1/publicinterfaces/*.h
myWorkspace/component1/module1/localinterfaces/*.h
myWorkspace/component1/module1/src/*.cpp
myWorkspace/component2/ImportedInterfaces/*.h --> need to exclude this folder
myWorkspace/component2/publicinterfaces/*.h
myWorkspace/component2/module1/localinterfaces/*.h
myWorkspace/component2/module1/src/*.cpp

myWorkspace also depends on two other workspace folders on the network with similar hierarchy:

\\machine1\home\users\myDependentWorkspace1
\\machine2\home\users\myDependentWorkspace2

below is my c_cpp_properties.json file:

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "//machine1//home/users/myDependentWorkspace1/**",
                "//machine2//home/users/myDependentWorkspace1/**",
                ],
            "windowsSdkVersion": "10.0.14393.0",
            "compilerPath": "C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/cl.exe",
            "cStandard": "c11",
            "cppStandard": "c++11",
            "intelliSenseMode": "msvc-x64",
            "browse": {
                "path": [
                    "${workspaceFolder}/**",
                "//machine1//home/users/myDependentWorkspace1/**",
                "//machine2//home/users/myDependentWorkspace1/**",
                ],
            }
        }
    ],
    "version": 4
}

=============================
for folder exclusion i have the following in my settings.json file:

"C_Cpp.intelliSenseEngineFallback": "Enabled",
    "C_Cpp.loggingLevel": "Debug",
    "C_Cpp.exclusionPolicy": "checkFolders",
    "files.exclude": {
       "**/ImportedInterfaces": true
    }

========================================
I see the following message in Log(Extension Host):

Workaround is to copy all these folders to a local folder(e:\folder or d:\folder). Include paths to local drive folders work fine. Is network drive folders supported in VSCode. If so, how do we point to it via includepath ?

Beginnen Sie mit dem includePath und den browse-Einträgen in c_cpp_properties.json sowie den Ausschlusseinstellungen in settings.json und reproduzieren Sie dann den Extension Host URI-Fehler anhand der angezeigten Pfade zu Netzwerkordnern. Prüfen Sie, ob unterstützte UNC-Pfade ohne den gemeldeten Fehler aufgelöst werden können; abgeschlossen ist dies, wenn Netzwerk-Includes ohne den Providerfehler funktionieren und der angeforderte Ordn er Ausschluss wirksam bleibt.
