关于AttachmentIds的Exchange行为 [英] Exchange behaviour regarding AttachmentIds

问题描述

大家好，

我发现当我以任何方式修改CalendarItem（添加/删除附件或只更改主题）时，此项目上已存在的附件ID已更改。这对我来说很奇怪。因为我在相反的系统中使用此ID进行复制。那么有什么方法可以依赖不可变的附件id？如果存在这种ID，我怎么能得到这个？我使用EWS，C＃

Hi All,

I've discovered that when I modify CalendarItem in any way (add/delete attachments or just change subject) attachment ids that already exists on this items are changed. It is very weird for me. Because I use this ids in opposite system for replication. So is there are any way to rely on immutable attachment id? If there are exist such kind of Id how can I get this one? I use EWS, C#
