I have created a pretty simple yet effective spreadsheet for creating bulk users in AD. Everything is cut in paste except one column, the Exchange store tab. I think I may need to use a VB script to automate this process, but if anyone has any ideas it would be great. Not a very savvy VB user. What I am trying to do is organize the names into exchange stores by last name. For example

A=A1
B=Random b1,b2,b3
c=c1
etc.

Can anyone help?
