[stephenf63688833]

Our entire organization utilzie Acrobat Pro and we have our corporate email accounts registered with that Admin Portal.   We are adding the Acrobat Sign service and we unable to add our corporate email addresses because they are already registered.   

Is there a way to add this service?

Are you acquiring Adobe Sign for Business or Enterprise?  If so, you need to ask your users to download their stored documents and ask Adobe to archive their account.  See more information on the attached document.
