I need to test UmAttOrder element , but how can I associate a new electronic voice message with one already sent voice mail.
If I send two Voicemail to the same recipient with the same subject, EWS server still treats them as two voice mails.
What I want to test is "Whenever a new electronic voice message associated with the same e-mail item is received, the new voice attachment is appended to the end of the list and all electronic voice attachments arerenumbered."
The problem is I can't addnew voice message to one already sent voice mail.
