Unnable to access to the URL of Sign up Verify Email

Hi, The fastest fix is for you to remove the user's invitation and send a brand new one. This creates a fresh, working verification link.

Hi ​@Hira Box, 

Welcome to Box Community, and we’ll be assisting you regarding the email confirmation error. 

By any chance, did the affected user captured a screenshot of his/her error? If yes, please attach the screenshot in this thread to get a closer look. 

In the meantime, for the completion of the user’s account registration. Remember that users can reset their password in order to have a brand new link and setup the password in their Box account. 

To reset the password for your Box account, follow this process:

1. Visit https://app.box.com/reset and enter the email address associated with your Box account.
2. Check your email, you will receive an email with a link to reset your password.

• Password reset links sent via email expire 3 hours after they are sent. If you need a new link after your current one has expired, visit https://app.box.com/reset to have another link emailed to you.
• If you do not receive an email from Box for this password reset, check to see if your Box account is associated with that specific email address or another email address.
• Also, check your spam folder in your email client for this email.

Hope it works, and please let us know how it goes!
