摘要
　　最近要在邮件提醒功能中添加，自动回复的功能。在移动端获取用户在outlook上是否开启了自动回复功能，如果用户在outlook上开启了自动回复功能， 获取用户自动回复的内容，如果没有开启，用户可以在移动端开启自动回复并且可以设置自动回复的内容，当然，用户也可以在移动端进行关闭。

一个例子
　　获取用户自动回复的信息。



    class Program
{
static ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
static void Main(string[] args)
{
service.Url = new Uri("https://xxxxx/exchange.asmx");
service.Credentials = new NetworkCredential("username", "userpwd", "domain");
var oofSettiing = service.GetUserOofSettings("username@xxxx.com");           
if (oofSettiing != null)
{
Console.WriteLine(oofSettiing.Duration.StartTime.ToString());
Console.WriteLine(oofSettiing.Duration.EndTime.ToString());
Console.WriteLine(oofSettiing.State.ToString());
Console.WriteLine(oofSettiing.ExternalReply.Message.ToString());
string msg = oofSettiing.ExternalReply.Message.ToString();
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(msg);
HtmlNodeCollection pLists = doc.DocumentNode.SelectNodes(".//p");
if (pLists != null && pLists.Count > 0)
{
foreach (var item in pLists)
{
Console.WriteLine(item.InnerText);
}
}
}
Console.Read();
}
}
　　注意获取的自动回复内容为html标签的，所以需要过滤，这里使用HtmlAgilityPack组件，对html进行解析。
　　如图所示

　　设置自动回复



  var myOOF = new OofSettings();
// Set the OOF status to be a scheduled time period.
myOOF.State = OofState.Scheduled;
// Select the time period during which to send OOF messages.
myOOF.Duration = new TimeWindow(DateTime.Now.AddDays(4), DateTime.Now.AddDays(5));
// Select the external audience that will receive OOF messages.
myOOF.ExternalAudience = OofExternalAudience.All;
// Set the OOF message for your internal audience.
myOOF.InternalReply = new OofReply("I'm out of office. I'll be back tomorrow. Thanks!");
// Set the OOF message for your external audience.
myOOF.ExternalReply = new OofReply("I'm out of the office but will reply to emails when I return. Thanks!");
service.SetUserOofSettings("user@xxxx.com", myOOF);
