EWS拉长订阅问题（每周） [英] EWS pull subscription issue with long gap ( every week)

问题描述

当我尝试在一周后调用GetEvents时，我遇到了EWS pull订阅的问题，Getevents在第一次调用时没有返回邮件即使经过多次尝试，我也可以在那一周收到所有邮件。

谢谢，

Chris

解决方案

如果检查服务器响应，则会收到错误或回复中的警告？文件夹中有多少项？ Pull订阅的最大超时时间为1440分钟，因此如果您未在该时间范围内更新，并且使用
重新订阅，则需要使用较旧的水印来强制服务器执行内容扫描文件夹，请参阅恢复在 http://msdn.microsoft.com/en中丢失了订阅-us /库/办公室/ dn458788（v = exchg.150）的.aspx 功能;.
文件夹中的项目越多，费用就越差。

干杯

Hi,

I am facing an issue with EWS pull subscription when I have try to call GetEvents after a one week of time, Getevents returns no mails in the first call even after try the multiple time only I can get all the mails in that week.

Thanks,

Chris

解决方案

If you check the Server response are you getting an error or warning in the response ? How many Items are in the folder ? The maximum timeout for Pull subscription is 1440 minutes so if you not updating it in that timeframe and resubscripting with the older watermark your going to force the server to do a liner scan of the folder see the recovering from lost subscriptions in http://msdn.microsoft.com/en-us/library/office/dn458788(v=exchg.150).aspx . The more items in the folder the worse the cost of this would be.

Cheers
Glen
