IMAP Email Issue

I have a IMAP user that gets some emails late (1-3 days late), however, not in batches. For example, email headers reads, Oct 7, but email does not arrive until Oct 9 but under Oct 7 received date. Email provider is stating that since emial headers looks fine ( no large time lapse between the SMTP exhanges, no problem there. User uses outlook 2007, all patched up to date, using symantec endpoint AV. I tried setting send/receive setting in outlook to 5 minutes. What else some I try to resolve user issue? Thanks.

You should check the headers of the e-mail. Right-click the message and choose Message Options from the menu. In the dialogue look into the Internet Headers box for any multi-line which begins Received: .

For example:

Received: from <removed> ([<IPaddress>]) by <removed> with Microsoft SMTPSVC(6.0.3790.4675);
       Tue, 18 Oct 2011 16:49:12 +0100
Received: from <removed> (<removed> [<IPaddress>])
      by <removed> (Postfix) with ESMTP id F3168A0C323
      for <e-mailaddress>; Tue, 18 Oct 2011 16:49:08 +0100 (BST)

The bottom-most Received line will be the original sender and that will likely match the date of the e-mail in your list. As you scroll up through the headers, you can determine when the message reached different servers and the last one is when the ISP received the message (and the message entered the mailbox waiting for IMAP4 collection).

email headers are match up, all very close, no large time lapse.

Have you tried adding the PST/OST file to the SEP exceptions?

I'll give that a shot since messages sent over encrypted connections can't be scanned anyway, I will add pst file for exceptions. Thanks.
