Hi
Whereabouts do you set the user name through the Access interface? Access is different to Excel in that you don't really save Access files but only the objects within so I don't if the username would be useful. I had a quick look through Options in Access 2003 and could not see a "Username" field anywhere.

Sub xxx()
Dim xl As Object
On Error Resume Next
Set xl = CreateObject("excel.application")
MsgBox xl.UserName
Err.Clear
On Error GoTo 0
Set xl = Nothing
End Sub
