Dear ​@Miki, welcome to the Box Community!

I usually see this message when the email address where you received the shared content is different from the one associated with your Box account. You must have a Box account linked to the email address that was invited to access the file or folder.

If the invite was sent to the same email address associated with your Box account, but you're still seeing an error, would you mind trying the following steps as part of our troubleshooting process to see if they help?

• Update your browser or OS to the latest version. You may check out this article to Understand the Box Policy For Browser And OS Support.
• Clear your browser's cache.
• Use Box with a different browser, computer, or network.
• Temporarily disable any internet security/firewall programs to check if they’re causing a conflict with Box (Note: you might need some help from your organization’s IT department/helpdesk for this).
• Temporarily disable any plugins/extensions in your browser
• Remove any unwanted extensions, plug-ins, ads, pop-ups & malware:
  • Chrome, Edge, Firefox, Safari

Thanks, and have a great day! 

I am new to Box and have a basic individual account. I joined to be able to collaborate with people outside of my organisation. They shared a link to a shared folder, on their enterprise Box account I believe. However, when clicking the link, I get this:
 

How do I troubleshoot? Is it an account settings issue? Is it the security on their end?

Thanks!

Hi ​@LucyHoppeUCL, welcome to the Box Community! I’ve moved your post to this related topic.

Please make sure that the email address where you received the invite is the same as the one you're using to log in to Box. It would also be helpful if the folder owner could double-check your permission level to view and access the shared content.

If the issue persists, please refer to the troubleshooting guides above.

I hope this helps. Have a great day!
