# Remove PSTs

To remove PSTs from outlook usw the code below. Copy it to a global configuration script. In the **afterFinalize()** function, call **removePstFromOutlook(true)** or **removePstFromOutlook(false)**.\
If the boolean parameter is true, PST files are moved to the recycle bin.

```c++
def afterFinalize() {
    removePstFromOutlook(true);
}


def isVirtualOutlook() {
    var reg=gkScript.openRegistry();

    return (!reg.readString("HKEY_LOCAL_MACHINE\\SOFTWARE\\WOW6432Node\\Microsoft\\Office\\16.0\\Common\\InstallRoot\\Virtual\\VirtualOutlook").empty() || !reg.readString("HKEY_LOCAL_MACHINE\\SOFTWARE\\WOW6432Node\\Microsoft\\Office\\15.0\\Common\\InstallRoot\\Virtual\\VirtualOutlook").empty());
}

def removePstFromOutlook(bool trash) {
    var progid = "Outlook.Application";
    var ol;

    if (isVirtualOutlook()) {
        ol = gkScript.createComObject(progid, false);
    } else {
        ol = gkScript.getComObject(progid);
        if(!ol.connected()) {
            gkScript.logInfo("failed to get outlook application, starting outlook..");
