Error delivering to XYZ\ABS mail\XXX.NSF; File does not exist

I have just moved few users from Server A to Server B, Server A is my admin and mail server. Server B users are fine with all functionality, they are able to send mails to everyone except one user XXX. When ever they send mail to that person they get this error and I quote “Error delivering to XYZ\ABS mail\XXX.NSF; File does not exist”. I have cleared the Cache, restarted the router and also the server, all the mails addresses to that person are pending in mail.box. I have check the Domino Directory for this person’s Person Doc, they read same on both Server A and Server B. I have seen a mail file move request for that person in Admin4.nsf, but that was not action. I was supposing that Create New Mail Field for that person on the Person Doc could have been updated with server B address. I don’t see any anomoly in the mail setup, I;m able to send mail to that person from a different server, so all seemed to be good. But this error and the problem is there. Please suggest any workarounds or fixes for this issue. Thanks in Advance.

Managed to get it resolved. I was gussing it right, on the user’s Person Document there was a hidden field which has Server B’s address, so is the error file Does Not Exists. Deleted the New Mail field, now all working good.
