Backup PSTs on Users PCs
Very useful, as some of my customers are "happy with POP". Hook it in with a GPO like so:




' Backup Users PST to network Share
On Error Resume Next

Set WshShell = CreateObject("Wscript.Shell")

Set objFSO = CreateObject("Scripting.FileSystemObject")
strUserName = WshShell.ExpandEnvironmentStrings("%username%")

'PST taken from default location and copied to a share on server
objFSO.CopyFile "C:\Documents and Settings\" & strUserName & "\Local Settings\Application Data\Microsoft\Outlook\*.pst" , "\\SRV1\Users\" & strUserName & "\"

Set objFSO = Nothing
