Depending on the email client (like Outlook, Gmail, Hotmail etc) and settings (firewalls, security), the registration confirmation email might end up in the user's junk/spam mail or trapped by a corporate firewall and therefore, undelivered.
As a grant manager, you can activate a user's account for them:
- Go to Users
- Find the user in question by typing the user's name or email address into Advanced search
- Click on the Confirm link next to the status "Awaiting confirmation"
This step will activate the user account and they can proceed to use their account. Manual confirmation does not trigger the notification so make sure you inform the applicant their account has been activated.
