Hello Everybody,
I have a situation where all of the common sense solutions have already been applied and now I need to reach out to the community to see if anybody else has experienced this issue.
I have an Exchange domain and Outlook clients. The messages almost always have the correct Sent times, however like the title sayssometimes but not always the Sent fields are different on two different users computers. This nature of this problem rules out all of the regular culprits like NTP not being enabled and Windows Desktop times being different.
The one thing that has caused this issue in the past is when Outlook is closed before the messages go out of the Outbox into the Exchange server. All the employees involved already know that and they don'tdeliberatly close Outlook anymore.
I'm using Outlook 2010 on all the clients and they are all on the same domain! Reviewing headers show that the messages aren't getting stuck in the mail relay process, which involves going to the Exchange Server and being sent out to the internet to get scanned by MxLogic, AKA McAfee Email Security, AKA Intel Email security. This part of the equation is most likely to be the real problem because it is black box as far as what they do to messages.
