Why does GetMemberMessages not return all "Unanswered" messages in a time range
Answer
At present GetMemberMessages API does not include any communication from third party email client application ( like outlook,gmail..etc.) and any messages originated from such email client.
That is the reason the GetMemberMessages response is missing some messages .This is how the API behaves at the moment.
