Exchange Server 2003, Outlook 2003 and Aspose Version 2011.10.28
We are trying to send emails in our .Net application using Aspose.Email.Exchange.ExchangeClient. We are not having any issues instantiating our ExchangeClient object using the MailBoxURI, Username, Password and Domain but when it comes to invoking the "send" method, we receive the following error message:
The remote server returned an error: (403) Forbidden.
Anyone else experienced this and could shed some lights? We thought our issues were with our Exchange/Outlook security policies but we tried updating our securities using these steps but without success:
As a test, we ran our application directly from the Exchange server, we increased all permissions in IIS for Exchange, and we increased the permissions in Exchange using System Manager.
We are out of ideas so any help would be greatly appreciated.
