We were setting up a church for office 365. We used the treasurer's email address as the admin / point of contact for verifying they were eligible for non-profit o365.
as we are starting to roll this out, we are going to portal.0365.com and logging in with treasurer's email address and password.
I realized this won't really work well - we would need to know his password whenever he changes it.
How do we change the email address as the admin for a company for o365 web page?
