My employer set us up with a company account. When I initialized my account and completed the setup process, I received 50 emails in 3 minutes to click a link to confirm my email address and activate my account. Each one that I clicked (over a dozen) would spin in a new window and then would give an error for invalid username. I am able to use the functions it seems, I am signed in to the document cloud, so I'm not sure why I would receive 50 emails (and no I am not exaggerating the number) to confirm my email address.
