Do you know if there's a way?
I've used this library to access a pop3 server, but it doesn't work with an exchange server.
Do you know of any other library or piece of code that'll show me how to do it?
I cannot change any settings on the server.
If you use Exchange 2007 and have web services enabled, this is pretty easy. I added a 2.0-style classic Web Reference to my VS2008 project, and I can get mail messages like this:
// exchange 2007 lets us use web services to check mailboxes.
using (ExchangeServiceBinding exchangeServer = new ExchangeServiceBinding())
{
ICredentials creds = new NetworkCredential("user","password");
exchangeServer.Credentials = creds;
exchangeServer.Url = "https://myexchangeserver.com/EWS/Exchange.asmx";
FindItemType findItemRequest = new FindItemType();
findItemRequest.Traversal = ItemQueryTraversalType.Shallow;
// define which item properties are returned in the response
ItemResponseShapeType itemProperties = new ItemResponseShapeType();
itemProperties.BaseShape = DefaultShapeNamesType.AllProperties;
findItemRequest.ItemShape = itemProperties;
// identify which folder to search
DistinguishedFolderIdType[] folderIDArray = new DistinguishedFolderIdType[1];
folderIDArray[0] = new DistinguishedFolderIdType();
folderIDArray[0].Id = DistinguishedFolderIdNameType.inbox;
// add folders to request
findItemRequest.ParentFolderIds = folderIDArray;
// find the messages
FindItemResponseType findItemResponse = exchangeServer.FindItem(findItemRequest);
// read returned
FindItemResponseMessageType folder = (FindItemResponseMessageType)findItemResponse.ResponseMessages.Items[0];
ArrayOfRealItemsType folderContents = new ArrayOfRealItemsType();
folderContents = (ArrayOfRealItemsType)folder.RootFolder.Item;
ItemType[] items = folderContents.Items;
// if no messages were found, then return null -- we're done
if (items == null || items.Count() <= 0)
return null;
// FindItem never gets "all" the properties, so now that we've found them all, we need to get them all.
BaseItemIdType[] itemIds = new BaseItemIdType[items.Count()];
for (int i = 0; i < items.Count(); i++)
itemIds[i] = items[i].ItemId;
GetItemType getItemType = new GetItemType();
getItemType.ItemIds = itemIds;
getItemType.ItemShape = new ItemResponseShapeType();
getItemType.ItemShape.BaseShape = DefaultShapeNamesType.AllProperties;
getItemType.ItemShape.BodyType = BodyTypeResponseType.Text;
getItemType.ItemShape.BodyTypeSpecified = true;
GetItemResponseType getItemResponse = exchangeServer.GetItem(getItemType);
ItemType[] messages = new ItemType[getItemResponse.ResponseMessages.Items.Count()];
for (int j = 0; j < messages.Count(); j++)
messages[j] = ((ItemInfoResponseMessageType)getItemResponse.ResponseMessages.Items[j]).Items.Items[0];
return messages;
}
The "messages" variable will be an array of ItemType objects returned from exchange that have all the properties you'd expect for a mail message (Body, Attachments, etc.). I hope this helps!
