HOW TO:Set folder level permissions using CDO 1.21 and ACL.dll

Articolo

This is not something everyone would want to do, but just in case below is the sample code that uses ACL.dll (found in the Platform SDK) to set "Reviewer" permissions on all the folders for a specific user.

The following sample is a simple VBScript code sample that iterates through all folders in multiple mailboxes and sets the "Reviewer" permissions. To use this sample, paste the following code in a new text file, and then name the file SetFolderPermissions.vbs:

 'This script logs on to a server that is running Exchange Server and iterates through all the mailboxes
'recursively setting the "Reviewer" permission on each folder for a specific user.

' USAGE: cscript SetFolderPermissions.vbs SERVERNAME DATAFILE FullUserName
' This requires that CDO 1.21 and the Acl.dll is installed on the computer.

Dim obArgs
Dim cArgs
Dim objSession
Dim objInfoStores
Dim FullUserName

Set obArgs = WScript.Arguments
cArgs = obArgs.Count

Const CdoMsg = 3,ForReading = 1, ForWriting = 2, ForAppending = 8, TristateFalse = 0

Main

Sub Main()
Dim FileSysObj
Dim DataFileName
Dim DataFile
Dim alias

    If cArgs <> 3 Then
        WScript.Echo "Usage: cscript SetFolderPermissions.vbs SERVERNAME DATAFILE(Name and Path) FullUserName"
        Exit Sub
    End If

    Set FileSysObj = CreateObject("Scripting.FileSystemObject")

    DataFileName = obArgs.Item(1)
    FullUserName = obArgs.Item(2)


    Set DataFile = FileSysObj.OpenTextFile(DataFileName, ForReading, False,0)
    
    'Read line by line
    Do While Not DataFile.AtEndOfStream
         alias = DataFile.ReadLine
    
    'Loop through the mailboxes
        Call IterateInfoStores(obArgs.Item(0), alias)
    Loop
   
    DataFile.Close

The list of mailboxes can be provided via a text file(Datafile). The Datafile contains the aliases of the users(one on each line). So assuming your Datafile is called "Aliases.txt" and is on the C:\, you would run the script as follows:

C:\>Cscript SetFolderPermissions.vbs Exchange2003 C:\Aliases.txt "Akash Bhargava"

The script currently sets and also dumps out the permissions on each folder in the mailbox.

The account that you are logged on the computer with must have permissions on the mailboxes that you are trying to iterate through. You can give the permissions by following the steps in the article below:

This works on Exchange 2003 for sure. I have not tested it on Exchange 2007.
