Atlassian On Demand, group created, unconfirmed email address (BB-7842)

Signed up for OnDemand trial with a BitBucket option.

On every admin page for the new Promax group, I'm getting this warning: "This account has an unconfirmed email address. If you haven't received a confirmation"

The email on file is promax@teams.bitbucket.org... doubtful that I can confirm this address.

If I try to put in my email address, I get the error "darian@promaxonline.com is already in use by another user."

Do i put in a third email address, or is this just a quirk with the OnDemand/BitBucket integration?
