E-mail from 1 Domain Not Delivered to 1 Recipient (of 2)
One of our clients sends an e-mail every day or so to two of our users. Beginning last Friday (5/29), one of the two users (User A) has not been receiving the e-mail though the other one (User B) still receives it without a problem. User A had been receiving these e-mails without problems for months (years?) until 5/29 and continues to receive all other e-mail without problems.
We have three servers: a domain controller/file server, an Exchange server, and an Exchange front-end server for Outlook Web Access. All are using Windows 2000 Server SP4, and the Exchange servers are using Exchange 2000 SP3. We have Symantec Mail Security running on the Exchange server, but have no filtering other than deleting any messages found to contain viruses. Workstations are all Windows XP SP2 with Outlook 2003.
Some other relevant (or not) facts:
- I'm not aware of anyone else having any e-mail problems at this time.
- No system changes, reboots, etc. were done on 5/29. In fact, I was on vacation (& I'm a one person IT department).
- User A has checked her junk mail folder - it's not there.
- I've looked at the message header info on the messages that User B received. I don't see anything different from those that User A received prior to 5/29, and the e-mail address for User B is correct.
- Both User A & B are listed on the "To" line of the e-mail and there is one "CC" to another user at the client's company. (I'm having User A see if they can send to her without any other recipients or CC's.)
- I've looked in Exchange Message Tracking Center, and I can see that the messages prior to 5/29 were delivered to both mailboxes, but there is no evidence of delivery (or not) to User A beginning 5/29.
- There is nothing out of the ordinary in Event Logs.
Any ideas?

I've tried a few other things today:
- I checked User A's Outlook. She has no rules set up, and when I searched her entire mailbox, I could not find anything from this client since 5/24.
- The client has tried sending directly to User A with no other To's or CC's, but we don't seem to get the message at all.
- User A has sent a message to the client and CC'd me. When the client replied, I got the message but User A did not.
So I'm leaning towards Sembee's viewpoint that the problem is not on our end. I'll be rebooting our servers tonight due to an unrelated issue, so I'll see if that does anything.
By the way, I got my dates confused. The problem started on Friday 5/26 (not 5/29). Nothing was sent to us on 5/25, so the problem could have started any time beginning the afternoon of 5/24.

Sorry bhaf I was pointing to check eventviewer.

I think I've cured the problem. I rebooted all three of our Windows servers on Thursday night (6/1), and User A has been receiving the e-mail in question since then. Don't know what caused it, and it had never happened before, but I'm glad it's gone.
Since the real problem is unknown and no one answer pointed me to a solution, I'm going to split the points to thank you for trying.
