using Microsoft.Exchange.WebServices.Data;

// 创建ExchangeService对象，连接到Exchange服务器
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
service.Credentials = new WebCredentials("username", "password");
service.Url = new Uri("https://example.com/EWS/Exchange.asmx");

// 创建搜索筛选器
SearchFilter searchFilter = new SearchFilter.ContainsSubstring(ItemSchema.SenderDomain, "example.com");

// 定义要获取的邮件属性
PropertySet propertySet = new PropertySet(BasePropertySet.FirstClassProperties);
propertySet.Add(ItemSchema.Subject);
propertySet.Add(ItemSchema.DateTimeReceived);

// 执行搜索
FindItemsResults<Item> results = service.FindItems(WellKnownFolderName.Inbox, searchFilter, propertySet);

// 遍历搜索结果
foreach (Item item in results.Items)
{
    Console.WriteLine("Subject: " + item.Subject);
    Console.WriteLine("Received Time: " + item.DateTimeReceived);
    Console.WriteLine("-------------------------");
