I'm currently trying to include exchange webservices 2007 functionality in a custom web application which is running on a Windows 2008 Server (IIS 7, Exchange Server 2007).

How do I access exchange 2007 webservices from my web application ? I currently use the defaultcredentials and receive an error, saying I don't have the required authorization (error 401).

Stating the credentials explicitly in the code works perfectly fine when trying to execute the code remotely, whether including the domain or not.

When executing the code locally on either the web server or my client computer, no problems occur. The web application I intend to write is supposed to run on the server and be accessed from any computer via my company's intranet.

The code looks something like this..

ExchangeServiceBinding binding = new ExchangeServiceBinding();

binding.Url = @"https://server/ews/exchange.asmx";

binding.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;

CreateItemType createItemType = new CreateItemType();

.. (creating item and setting it's properties)

try

{

CreateItemResponseType createItemResponse = binding.CreateItem(createItemType); <- the error seems to occur here } catch (Exception ex) {

Response.Write(ex.ToString()); <- results in error "unauthorized"

}

The authentication settings in IIS 7 are as follows:

anonymous authentication: deactivated

ASP.NET multiple identities: activated

digest authentication: deactivated

forms authentication: deactivated

standard authentication: deactivated

windows authentication: deactivated

User permissions set:

SYSTEM: full access rights

(windows user): full access rights

IUSR: full access

I have a big problem. I have a VB application that gets users from Exchange server, and gets their calendars using MAPI.

Now I'm porting that application to .NET and I'm using Exchange Web Service API. The problem is that I can't take the PR_STORE_ENTRYID Property of the contact. Within the old code, I took it by AddressEntry.ID and I store that in database, and now I should take that StoreID with EWS API, but I don't know how. I know that I should use ExtendedProperties, and PropertyID = "Ox0FFB", but have no idea in which way :(

Please, I appreciate if you can help me.

Regards

I am working on a problem where I want to decode a TNEF encoded MIME message. I am using the class Base64Decode in Microsoft.Exchange.data.Mime namespace and I am also able to decode the message if it doesn't contain an attachment . But , for a TNEF encoded message without attachment , the conversion fails. Do you have any suggestions ? Please help .

In addition to that , could you provide me some sample code to parse a MIME message using MimeDocument,MimeReader and Tnef Reader classes?

Thanks in advance

If it's possible to issue HTTP requests from your mobile, then you should be able to use a web service. So - however you would use a web service from there, you can adapt that to use EWS.
