hi all,

i have just completed a move form SBS2003 to full 2003

i have a completely new domain and the exchange mail boxes were exported/imported with exmerge

old domain -
new doamin - company.local

exmail address have remained the same as

i have an issue with a few users where if someone they emailed externally last week tries to reply to them they get a bounce back. a new email to the user works fine.

i think, although i dont know it is something to do with  the usernames.
the particular user i have issue with had old accounts of firstnamelastname1 (profile reasons ended up in them getting new log ons.)
they are now firstnamelastname.
the email addresses have always remained the same of
the mail boxes were renamed to match the new names on import.

any ideas.

    this could be due that fact that legacydn value has got changed since the mailboxes and domain are new.
    you could try adding a X500 entry in the user's email address tab via AD
    the X500 value should point to the old domain

    if this is exchange 2003 then you can add X500 addresses
    click on new and select "custom address" from the list
    then type X500 in the "email type" box and the X500 address in the "email address" box
