Hello,
We have an issue where our POP users do not see the time an email was sent to them at once they recieve the email in thier inbox. When connected to webmail the Sent time is showing, when connected through Exchange the Sent time is shown but when the mail is downloaded by the POP connection they see None as the time the email was sent at. We have 2 cas servers in the cas array and 2 database and transport servers, all servers are running Exchange 2010 SP3.
