Profiles Email Address

I'm guessing you could create a process model which first loads the usernames of all users in a specified group (and by that i mean you'd feed in a group containing all users you want to update), then iterates through them one by one and uses the update user info smart service node to set the email address to whatever you like - it could either be the same thing for all, or something dynamic based on their username or user details, pretty easily. It would even work for 45,000 users though you'd have to batch up your MNI calls so that none of them exceed 1,000 (divide into subprocesses, etc).
