Question

Exchange Web Services 2010是否可以从任何电子邮件地址在邮箱中创建邮件？

所以场景是这样的; 用户收到电子邮件服务在SQL中搜索电子邮件和存储（将消息存储为XML）然后从邮箱中删除电子邮件时间流逝... 服务采用SQL版本的电子邮件并创建回原始邮箱

我们之前遇到过一个交换安全问题，它不允许我们使用域外任何人的发件人对象创建电子邮件。例如，Mike @ MyDomain.com工作正常，但Bob@Microsoft.com无效。

我显然可以看到与解除此限制相关的安全风险，但这是我需要构建的系统的要求。

创建消息的实际代码在这里（大部分代码来自MSDN）;

public void CreateEmail(string FromAddress, MessageType message)
    {
        ExchangeServiceBinding esb = getExchangeServiceBinding(FromAddress);

        // Create the CreateItem request.
        CreateItemType createItemRequest = new CreateItemType();

        // Specifiy how the created items are handled
        createItemRequest.MessageDisposition = MessageDispositionType.SendAndSaveCopy;
        createItemRequest.MessageDispositionSpecified = true;

        // Specify the location of sent items. 
        createItemRequest.SavedItemFolderId = new TargetFolderIdType();
        DistinguishedFolderIdType sentitems = new DistinguishedFolderIdType();
        sentitems.Id = DistinguishedFolderIdNameType.sentitems;
        createItemRequest.SavedItemFolderId.Item = sentitems;

        // Create the array of items.
        createItemRequest.Items = new NonEmptyArrayOfAllItemsType();

        // Create a single e-mail message.
        MessageType newmessage = new MessageType();

        //Can't seem to restore the original message.
        //If part of the email is being lost when restored then it's happening here.
        //import original message into newmessage
        newmessage.Subject = message.Subject;
        newmessage.Body = message.Body;
        newmessage.ItemClass = message.ItemClass;
        newmessage.Sender = message.Sender;
        newmessage.ToRecipients = message.ToRecipients;
        newmessage.Sensitivity = message.Sensitivity;
        newmessage.ExtendedProperty = message.ExtendedProperty;
        newmessage.DateTimeSent = message.DateTimeSent;
        newmessage.IsRead = true;

        // Add the message to the array of items to be created.
        createItemRequest.Items.Items = new ItemType[1];
        createItemRequest.Items.Items[0] = newmessage;

        try
        {
            // Send the request to create and send the e-mail item, and get the response.
            CreateItemResponseType createItemResponse = esb.CreateItem(createItemRequest);

            // Determine whether the request was a success.
            if (createItemResponse.ResponseMessages.Items[0].ResponseClass == ResponseClassType.Error)
            {
                throw new Exception(createItemResponse.ResponseMessages.Items[0].MessageText);
            }
            else
            {
                Console.WriteLine("Item was created");
            }

        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }

我现在已经解决了这个问题。没有安全限制。使用Exchange WebServices，此代码工作正常。限制是使用托管Web服务API。创建消息时无法更改发件人/发件人对象。
