Exchange 2010 mail is arriving 8 days late.

I have a user receiving a particular email 8 days late.  Other users receive that same mail on time.  Any ideas?

You need to look at the header on the actual email.  Also, check your exchange server using Exchange Message Tracking tool to see when did it actually came in.  Do they match (day and time received)?

That's the only way you can be sure of when the message really came in.

Are you using a DAG?  Is this user at a remote office?
If you have an anti-spam appliance then you need to check that as well to see when that email actually came in.  You want to check your front-most email receiver then work inward from there if the problem is at your end.

In any case, if the email touched your receiving side correctly (8 days late) then the problem is with the sender.  If the email came in 8 days ago and you just got the email today then the problem is at your side.  You should be able to see/trace the email came into your anti-spam appliance then to your email server, etc.

In any case, you need to investigate where the problem lays.

No DAG is used.  Barracuda appliance is passing all the traffic to Exchange.  All time stamps are correct.
Okay, so you're saying:

1. Email was received correctly in Barracuda (it came in 8 days ago)
2. Barracuda also passed the email to Exchange 8 days ago
3. The email showed on 1 recipient 8 days late
4. Other recipients can receive email on time.  It's just one user affected.  Were the other recipients copied on this same email?

If you check OWA and if you take Outlook off cached mode, do you see the correct time stamp?
