Microsoft.MetadirectoryServices.AttributeNotPresentException: Attribute "blah" is not present.


  • Hi,

    I am trying to write a custom extension in Visual Basic that creates Exchange mail-enabled users (MEUs) in my target directory, for each mailbox in my source directory. I have the code below in my source MA extension, and have specified "targetAddress" as the flow rule name under the advanced attribute flow on the source MA. However, when I run a sync on the source MA, it returns the error "Microsoft.MetadirectoryServices.AttributeNotPresentException: Attribute "targetAddress" is not present."

    Any idea what I could be doing wrong?

    Thanks in advance,


     Case "targetAddress"
                    If csentry("targetAddress").IsPresent Then
                        mventry("targetAddress").Value = csentry("targetAddress").Value
                        mventry("targetAddress").Value = ("SMTP:" & csentry("mailNickname").Value & "")
                    End If

  • Can you paste the whole exception?

    Thanks, Brian

  • Hi Brian,

    This is everything from the Call Stack Information:

    Microsoft.MetadirectoryServices.AttributeNotPresentException: Attribute "targetAddress" is not present.
       at Microsoft.MetadirectoryServices.Impl.AttributeImpl.get_Value()
       at Mms_Metaverse.MVExtensionObject.Provision(MVEntry mventry)

    Extension File Name: MVExtension.dll

  • So that's in your Provisioning code but you pasted a rules extension. Can you check your provisioning code?

    Thanks, Brian

  • Hmmm, interesting, so here is a portion of my provisioning code. I am using the ExchangeUtils.CreateMailEnabledUser method:

       dn = adMA.EscapeDNComponent("CN=" + mventry("cn").Value).Concat(container)
                    If 0 = adMA.Connectors.Count Then
                        If mventry("legacyExchangeDN").IsPresent Then
                            csentry = ExchangeUtils.CreateMailEnabledUser(adMA, dn, nickName, targetAddress)
                            csentry("proxyAddresses").Values.Add("SMTP:" & mventry("mail").Value)
                            csentry = adMA.Connectors.StartNewConnector("user")
                            csentry.DN = dn
                            If mventry("mail").IsPresent Then
                            End If
                        End If

  • Where do you set the targetAddress variable?

    Thanks, Brian

  • It was up above from what I sent you, here:

    Public Sub Provision(ByVal mventry As MVEntry) _
        Implements IMVSynchronization.Provision

            Dim adMA As ConnectedMA
            Dim csentry As CSEntry
            Dim nickName, mailboxMDB, SMTPemail, targetAddress, container, stralias() As String
            Dim dn As ReferenceValue
            Dim sid As Byte()

            If mventry.ObjectType = "person" Then
                    adMA = mventry.ConnectedMAs("PRD")

                    nickName = mventry("uid").Value
                    targetAddress = mventry("targetAddress").Value
                    'mailboxMDB = mventry("info").Value
                    sid = mventry("objectSID").BinaryValue

  • Brian,

    Thanks for the tip. Even though you never responded to my last post, your question about where I was setting the targetAddress variable got me thinking. I changed the variable to the following, and things started to work!

    targetAddress = ("SMTP:" & mventry("mailNickname").Value & "")

  • Sorry I missed the last reply yesterday. Yes that will work - it will fail though if mailNickname is never null. You may want to do the IsPresent test and throw an UnexpectedDataException if you're missing mandatory attributes.

    Thanks, Brian
