Exchange delete the email

User had complained that he received only 1 email instead of 2. When we do message tracking, there is 1 email was detected as duplicate on exchange. However the message id was different. Based on attachment, the duplicate cause by message id & client submit time? May i know what does the client submit time mean? It mean time when exchange accept the message? It is possible the application sent 2 emails with different message id with same time?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

client submit time is the time when the message is submitted (sent) by the outlook client, and yes it is possible to have 2 emails with different message id in the same time (same time refers to the time when the message is considered submitted) and this usually happens when 2 or more clients are connected (online mode) using the same mailbox at the same time.
