Hi, I know this is not a right place to ask this qn, but I cant find any other relative forum as well? I am trying to connect to our company's 'Microsoft Exchange Server 2007 ' using Java Mail API. I was able to send emails after enabling relays (I am not sure what it means). But I am facing problem while reading the emails. My application code throws Authentication error, which works fine while sending email. Is there any setting on server side which can prevent read operation from third party application like Java Mail API. Can someone please let me know what all possible options that could prevent me from reading emails using Java Mail API. Your help is appreciated. Thanks, Hanumant

You should try to post your question in the Exchange Development Forumhttp://social.technet.microsoft.com/Forums/en/exchangesvrdevelopment/threads While most of the discussions are concentrated around the EWS Managed API, VBScript and PowerShell, some Java-related issues have been talked over as well. The topics discussed include Web services, APIs, application conversion and apps in general.MCTS: Messaging | MCSE: S+M | Small Business Specialist
