Duplicate Internet Address

[Bakgome]

In our company a user named John Smith uses jsmith@abc.com for his address and James Smith uses jamessmith@abc.com. When John Smith left the company, James Smiths wanted to use jsmith@abc.com account. After deleting a old jsmith account, I tried to add jsmith@abc.com address to jamessmith@abc.com. But I keep getting error indicating that the address already exists. I've checked everywhere to locate the duplicate account and could not find any. Can anyone suggest a solution for this???
Would appreciate your help.
Thank you.

Assuming you have successfully deleted the user and have successfully replicated, find a workstation and type in jsmith@abc.com and do a check name. This will resolve it and you can find out who has it.

You may want to run the DS\IS consistency checker. It is possible that for what ever reasons part of the original mailbox was orphaned. You can find this in the advanced tab of the properties of the server in question. I haven't used this utility in a while and don't remember all of the ramifications involved with running it, so you probably will want to research it a little on MS site or wait for someone else to second or third my opinion. Good luck.

Thanks for all your suggestions.
First, the name jsmith does not resolve at the workstation. I've tried this already.
Second, according to MS, running the DS/IS consistancy check should be done with caution. I will need to do some more research on this consistancy checking.
If anyone has other suggestions, please feel free to let me know.
Thank you.
