Open active directory from the exchange server and find the user. Go to the email addresses tab of the user and change his smtp address to something different.

Hope this helps.

why change it? is there no other way around it? he doesn't want it changed.

and i can't think why somebody else would have the same address. how can i check if that is actually the case?

This also may be of help as I had a somewhat similar issue a couple weeks ago:

http://flaphead.dns2go.com/archive/2007/11/09/550-5-1-4-resolver-adr-ambiguous-ambiguous-address.aspx

And here is a bit more clarification for my specific issue that I added:

To find the duplicate SMTP address (which is why this error/NDR happens) - Either right-click on the domain name in your AD Users & Computers MMC, or click the Find toolbar button. Click on the Find drop-down and select Custom Search. Click on the Advanced tab and copy/paste the following LDAP query:

(&(objectCategory=*)( proxyaddresses=smtp:something@somewhere.com))

Change the "something@somewhere.com" address to the email address specific to your organization that you're having a conflict with. Click on the Find Now button. This will display items/objects associated with the SMTP/proxy address. Delete the non-needed/conflicting object to resolve this NDR error/msg.

For me, I had a legitimate distrib group and a MS Exchange Sys Object Public Folder (of which I didn't know where it came from). Both had the same SMTP address. Since I wasn't comfortable where or how the Sys Obj Pub Folder got created and what it was for and not able to see any associated address in AD Users & Comps, I went into ADSIEDIT. I drilled down in ADSIEDIT to where this object was, removed the SMTP address associated with it (as noted by the attritbute "proxyAddress" in the CN object properties), and this resolved my issue.

Hope this helps you.
