X400/X500 additional address Exchange Server 2003 - not working for some users

HI,
After exporting a mailbox content, deleting the users mailbox and importing all the content again I ran into the issue of internal email bouncing when any mail was sent to this user. I was kindly directed by The Geezer2010 to an article which addressed the same issue and I (think) I followed the instructions and it seemed to work ok but I am still experiencing some issues that have not settled yet.

I added the old (additional) x400 address to the mail properties of the user from whom I created the new mailbox,  in AD but it doesn't seem to work for some users. Still getting NDR's. When I check from the affected user client pc, in outlook properties, email addresses, I can see that the additional x400 address is there.  A couple of points I wanted to clear up.

1. The user got married some time ago and I changed the display name to her married name. So the original x400 address on the client pc's looked like this:   x400:c=GB;a= ;p=mycompany;o=Exchange;s=Smith;g=Sue
When the new mailbox got created it created the new x400 entry as her married name in AD and there was no entry for the old one -  I understand that this is the reason for the ndr's - the clients have the old address but the new mailbox had the new address associated .

2. When adding in the old x400 address to the email address properties of the new mailbox I went to fill in the boxes but noticed that the 'a' entry was blank in the original but the UI would not let me leave the 'a' box blank - I had to put something in. So I put 'mycompany' in twice effectively.   Both the 'a' and'p' attributes are 'mycompany'  Would this have any bearing on why a small number of users are getting NDR's?

The NDR:   The e-mail account does not exist at the organization this message was sent to.  Check the e-mail address, or contact the recipient directly to find out the correct address. #5.5.1

Any more info much appreciated - Thanks

HI TheGeezer2010.

It appears I have not followed the instructions you previously supplied - what I did was to add in to AD the x400 address - - apologies for my muppetry....

So - using ADSIEDIT I can see  the users legacyExchangeDN and have pasted it into an Outlook client and it does indeed resolve to the user in question.  When you say "add this in as an additional x500 address to the account"  Do you mean in the Email Address properties of the ADUC  as a custom address?  Thanks again
Exactly that - take a look at the first link I sent you. I hope this fixes the problem !!
Thanks - done that,

if it fixes it, it would have been a 2 minute job that I have managed to string out for far too long -however, its uncharted territory for me, and therefore a learning experience. Thanks again.
Welcome !!
