My email connection needs admin approval
If you are trying to connect your Office365 email account in FrontSpin and it says "Need Admin Approval," that means your email administrator needs to approve that connection. They will know what to do on their side, so reach out to your email administrator.
If your email administrator would like to grant the ability for all users to connect their emails to FrontSpin without need admin approval, here are the steps to enable that...
1) Login to http://portal.office.com/, then go to the ADMIN settings.
2) Go to Settings => Org Settings.
3) Select "User consent to apps" and enable "Let users provide consent when apps request access to your organization's data on their behalf."
Now users will be able to connect their emails to FrontSpin without need admin approval.
