I'm trying to read and modify the ACL of a mailbox in Exchange 2003 using a VBScript. I can read and modify the user object ACL no problem, I just can't access the mailbox ACL. I have ESM installed on the computer I'm running the script on as well.
Set objsd = objUser.Get("msExchMailboxSecurityDescriptor")
...but I get "The directory property cannot be found in the cache."
Any ideas to access the mailbox ACL in VBScript?
