I hope someone can help. Every few weeks (happened yesterday afternoon too), we experience a long delay in receiving our emails. I have confirmation that our clients are sending emails to us, but neither my exchange queue or my spam filter monitor show them as incoming emails. And our clients are not receiving an NDR. After 1-3 hours, they finally start to come through and the messages are time-stamped for the time that they were sent to us (i.e. message arived at 4:42 pm yesterday, but the time on the email says it was sent at 2:18 pm). Any ideas? Outbound or internals emails sent are no problem

Hi, Please confirm is there a gateway scanning server(mail scan), if there is please check the mail status there if not please track the message in exchange & see the time at which server has received the mail or check the header of the mail for the same.Ripu Daman Mina

Please describe the exchange topology Does the symptom happen to mails from specific external domains? The symptom can’t happen permanently, can it? Does the mail delay happen on OWA as well? Please check the timestamp in t the header of the delayed messages, and also message tracking logJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

You can enable protocol logging on your Receive Connectors to gather information about mail flow and SMTP conversations into your organization. See these articles:http://technet.microsoft.com/en-us/library/aa997624(EXCHG.80).aspxhttp://technet.microsoft.com/en-us/library/bb124531(EXCHG.80).aspxBy default, the protocol log files will be placed in C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive

Our topology is quite simple. hub-transport, Two receive connectors (client and default, ports 25 and 587), 1 mailbox and 1 public folder database, 15 mailboxes, OWA enabled. What else should I mention? Symptom only occurs when receiving from external domains Only occurs every few weeks and last form 1-2 days. Delay happens with OWA as well The messages are time stamped for when the sender sends the message. When I receive them, Outlook stamps them for the time they were received to my inbox, but if I open up the message, I can see the correct time-stamp for when it was sent.

Agree with maumen, please also use the protocol log and the message tracking log to check the time that the delayed mails entered in your orgJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

Is this a problem with Outlook 2003? http://support.microsoft.com/kb/2009942 You don't say what SP or Rollup Update of Exchange 2010 is installed, so I'll just say that you should be running SP2 RU3v3 (that would be the one here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=413b8979-76b8-4be4-a18b-015d025eb368&displaylang=en). --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
