Destination. ID number changed

Question

I created a meeting, the meeting room is [e-mail] , and I impersonated [e-mail] as a user .

but when I find FindAppointments from [e-mail] , the identifier is A., when I find FindAppoint from room [e-mail]. identifier is B.

Why is the identifier different?

I use [e-mail] to make an appointment, and saved the .ID.UniqueId assignment to the database. but I need to show AllBookings in the system, so I have to get room meetings. but the same destination id is different, I cannot make it relative to my database.

Answer 1

The identifier you are referring to is EWSId, which is unique for each item in the Exchange store. Although it has the same purpose in one mailbox, it is physically a separate object in the Exchange store, so it has a different EWSId, see http://technet.microsoft.com/en-us/library/bb123495%28v = exchg.141% 29.aspx . If you work with meeting IDs, I suggest you use PidLidCleanGlobalObjectId http://msdn.microsoft.com/en-us/library/office/cc839502%28v=office.15%29.aspx . You can use this property to find a meeting in any Attendee calendar, as well as in any responses, invitations.
