weird issue at a customer:
Situation: Reading Mailbox messages from inbox via Exchange Web Services (Exchange 2016) in .NET
msgCollection = myClient.ListMessages(myClient.MailboxInfo.InboxUri);
Issue: As soon as there is a Meeting Response message in the inbox (Accept, Decline …), the properties “From” and “MessageId” for all elements of the ExchangeMessageInfoCollection are null.
Would there be any way to create a filter - so that these kind of messages are ignored?
