Hello Luciano,

you can get the correct url by issuing a PROPFIND on the base folder of your
mailbox querying the properties mentioned in this article:

You can use also code below:

'1 Way -  For current user (for example, current session user for asp,
asp.net etc.)
Set oPerson = Createobject("CDO.Person")
Set oADsInfo = CreateObject("ADSystemInfo")
oPerson.DataSource.Open "LDAP://" & oADsInfo.UserName
Set oADsInfo = Nothing
'------------
'2 Way -For some user (your script must be executed with Administrator or
Exchange Domain Servers groups priveleges!)
sUserMail = "user@exchange.com" '  example account
Set oPerson = Createobject("CDO.Person")
oPerson.DataSource.Open "mailto:" & sUserMail

  Set iMbx = oPerson.GetInterface("IMailbox")
  sFolderName = iMbx.Inbox '   or iMbx.SentItems, iMbx.Outbox, iMbx.Tasks,
iMbx.Calendar

'If You need to know full path for some user folder You can use this code:
sUserAlias = Split(sUserMail, "@")(0)
sDomainName = Split(sUserMail, "@")(1)

sExchPath = "file://./backofficestorage/" & sDomainName & "/MBX/" &
sUserAlias & "/" & sFolderName
' or
sExchPath = "http://" & sDomainName & "/exchange/" & sUserAlias & "/" &
sFolderName

Enjoy!
Alexander.
