Exception when fetching eMails

Dear Aspose-Team,

we are evaluating your Networking-Components.

We want to fetch e-Mails from an exchange server,
Unfortunately we are getting exceptions from your component:

Object Reference not set to an instance:

{“Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.”}
System.NullReferenceException: {“Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.”}
Data: {System.Collections.ListDictionaryInternal}
HelpLink: Nothing
InnerException: Nothing
Message: “Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.”
Source: “Aspose.Network”
StackTrace: " bei Aspose.Network.xb48d0c971e5c9051.get_Length() bei Aspose.Network.xb48d0c971e5c9051.Read(Byte[] buffer, Int32 offset, Int32 count) bei Aspose.Network.x465598d3637eaed7.x3ad8e53785c39acd(Stream x50a18ad2656e7181, Stream x6b8e154b42d5c1e3) bei Aspose.Network.Imap.ImapClient.SaveMessage(String uniqueId, Stream output) bei Aspose.Network.Imap.ImapClient.SaveMessage(String uniqueId, String fileName) bei IMAP_Queue_Aspose.getMailQueue(Collection& inQueue, XmlDocument objXML, String strLicencePath) in C:\IMAP\E-MAIL-SERVICETEST-IMAP\E-MAIL-SERVICETEST-IMAP\Modules\IMAP_Queue_ASPOSE.vb:Zeile 123."
TargetSite: {System.Reflection.RuntimeMethodInfo}


This is the code we are using:

Do While i < list.Count
'save the eml file locally
Try
objASPOSEIMAP.SaveMessage(list(i).UniqueId, “c:\temp” & list(i).UniqueId & “.eml”)
i += 1

'Threading.Thread.Sleep(100)
'Application.DoEvents()

Catch ex As Exception
Stop
End Try
Loop

If we uncomment the Sleep-Statement then it works …

Kind regards,

Peter
