EA portal and already an account created

Hello, 

Created a new dept. and now trying to add an account under the ea.azure.com. 

i get this error.

"There is already an account created for the specified email ID. Please enter a different email ID."

My account is associated with another subscription and another account under azure  but I would like to get the subscription setup before handing it off to the person who will manage going forward, once that is figured out.
