I'm having a problem with this as well. I keep getting this message when I follow the link in my email:
Uh oh, something went wrong trying to verify your email address. One of the following might be the issue:
* Your address has already been verified. Check the status of your address on the your settings page.
* Something isn't setup quite right. Either try again by refreshing, clicking the verification link again or visit your settings page to make sure everything is configured correctly.
* The link in your email is for an old address or has been corrupted. Click this link to send a fresh verification email. For security reasons we only allow one resend of this email per 24 hours.
* Checked all those things? Still having issues? Send us an email at Bungie.net Bugs
