PowerShell監控outlook新郵件到達（單封，多封可能要分解id(舊版需分解？新版不需要？新版就是每個郵件出發一次newmailex?看如下documents)）

This event fires once for every received item that is processed by Microsoft Outlook.
The item can be one of several different item types, 
for example, **[MailItem](https://docs.microsoft.com/en-us/office/vba/api/outlook.mailitem)**, **[MeetingItem](https://docs.microsoft.com/en-us/office/vba/api/outlook.meetingitem)**, or **[SharingItem](https://docs.microsoft.com/en-us/office/vba/api/outlook.sharingitem)**. 
The *EntryIDsCollection* string contains the Entry ID that corresponds to that item. 
Note that this behavior has changed from earlier versions of the event when the *EntryIDCollection* contained a list of comma-delimited Entry IDs of all the items received in the Inbox since the last time the event was fired.
