Exchange User can not email to one other internal user

I have a 2 server Exchange 2003 environment.  The issue i am having is domainuserA can not email domaimuserB.  But B can email A (all internal mail, single domain).  I get no NDR and exchange message tracking shows the email as delivered to user B's inbox.   But its not there.  I disabled symantec mail security and looked in the quarantine logs but its not there.  Besides mail security emails my admin account when it does anything and there is nothing about blocking this email there.

For testing I created another user on the same mailbox store as User B and A was able to email and receive my mail.
I then created a user on the Mailbox store with UserA and again was able to send/receive all around.

UserA can send out to external email addresses with no issue and to everyone else internally with no issue.  It doesn't seem to be a mailbox store issue either as the above test showed.  There are no mailbox filtering rules in place for sizes etc...

This all points me to userB's Outlook rules.  But i checked and while they have 15+ rules none are for UserA.  I checked outlook junk mail and nothing.  Deleted Items nothing.

Where is this mail going if it shows delivered by message tracking?  It follows the same path from exchange server 1 to exchange server 2 to delivery to local mailbox as test mails from other users that worked.

I'm sort of out of ideas and was wondering if anyone came across this?  

(I dont want to start thinking of recreating the user/mailbox exporting/importing mail etc... just yet)

Thanks

Did you search the mailbox using the senders email?  I run across similar issues and its always been there but just moved or something easy.  Also login to OWA and search for it or login from another machine.

If user A replies to B does it work?

I have been testing using OWA.  If A replies to B or if A uses the GAL it still does not get to the inbox.  I also agree it should be something simple and should be in the inbox.  But i can not find it.  I have done a search in OWA included subfolders on UserB via OWA and could not find any mail from UserA.

UserB has a large mailbox with many subfolders, would be easy to see if they just had a single small inbox.  Search comes up with nothing, but to be honest i dont trust Exch 2003 OWA search.

I'm curious when you send from A to B does the amount of emails in the inbox go up?  In owa its on the bottom where you page back and forth.  Or if you look in Exchange system mgr does the total items increase?

Have you searched by email address, I'm assuming yes but have to ask.

Excellent call to look at that.  Exchange system manager - the mailbox for UserB does go up by 1 item every time i send an email from userA.  Damn OWA hangs on UserB's 10GB mailbox.  Gotta love big mailboxes.

Is there no way to test it will the full client.  Obviously a pain but might be necessary and easier to search.

Excellent suggestion.  That caused me to take the painstaking journey through the giant inbox/sub folders.  Found the buried sub folder where the email was being put.  Now to see which of the 20+ rules is causing this.

Thanks again.
