Hi ​@Alouviere, welcome to the Box Community, and congratulations on your wedding!

To get started regarding the issue, have you already confirmed your new email by navigating to your profile > Account Settings? Once verified, you can set it as your primary email and remove the old one.

If you're still having trouble receiving Box notifications or accessing folders, here are a few basic troubleshooting steps that often resolve common access issues:

1. Check our Troubleshooting Issues with Email Notifications for helpful tips.

2. Try clearing your cache and cookies, or use a different browser and access Box in incognito mode.

3. If you're unable to access certain folders, verify if they are owned by someone you're collaborating with. In that case, please contact the file owner and ask them to review and adjust the sharing permissions or send you the correct link using your new email address.

I hope this helps resolve the issue!
