can any body give me solution

can any setting need for iis or exchange server

or any other solution
please help me out

Hi,

Aspose provides .NET component for accessing emails from Exchange Server mailbox. Please visit http://www.aspose.com/documentation/...ge-server.html for details. You can use Aspose.Network in any .NET project type e.g. ASP.NET, Windows Forms, Console, Web Service etc

There are 21 different ways to talk to Exchange.

I think you're looking for ADSI/Directory Services, if you want to access sender information.

Hello shanawazpatel,

When you are posting code into the forum, can you make sure you wrap it in CODE tags, it makes it a lot easier to read, and people will be more likely to look at the code if they can see it clearly.

Does the identity that is running the Application Pool of your ASP application have access to the Exchange Server?

Gary

Can you use WebDAV to access MS Exchange Delegate information from a .Net application? Also, updating MS Exchange Delegate information through the .Net app? The Exchange Server is 2003. I need to write a web application that can view and modify delegate information. Is this possible? Can I use MAPI, CDOEXM, or WebDAV to do this?

Any information is very much appreciated.

Thanks

Hey,

Have you read the link that Mendhak posted?

It pretty much sums up all your options.

Gary

Thanks for the fast reply. The link lists over 20 ways to do it. Wondering if anyone knows how I can do it without researching the 20 different ways? Again, I need to view and edit Exchange/AD Delegate settings through a .net web application. The web application will be running on a different server. It is Exchange 2003. Any quick thoughts or recommendations would be appreciated. If someone can guide me down the right path I can look down that path in detail.

Thanks again,

Hey,

I personally couldn't say, as I haven't played with all of them.

I guess you would at least have to do some investigation on all of them in order to understand how they are different, so then you can make in informed decision.
