I'm adding some users using a .csv file. Our campus login ID's are 6-character login ID's so I'd like the login ID to be the same for the AGO account, however, after I select the .csv file and review the accounts that will be created, it's adding a random number to a few of the accounts. I try to edit the user name & remove the number, but it adds a different number. I've verified that an account with that username on our Org. does not already exist. Help?
