Hi Tom,
While the email value must be unique for each user, the WAEMAIL field is case sensitive. So in a sense you can map the same email address to multiple acids by changing the case of 1 or more of the letters. For example, if I have acids BOB1 and BOB2 and 1 email address (ie BOB@***.com), I can do the following:
TSS ADD(BOB1) WAEMAIL(BOB@***.com)
TSS ADD(BOB2) WAEMAIL(Bob@***.com)
Best regards,
Bob Boerum
