Hi ​@omata,

Welcome to Box Community, and we’d love to help with your Box notifications!
 

I've investigated our email server logs and your email address is not on our bounce or suppression list. 
 

Please check your Spam/Junk email folder. Sometimes, certain email clients do not recognize email from box.com. If you find Box messages in your Spam or Junk folder, add noreply@box.com and no-reply@box.com to your email contacts, or Safe senders list. This will allow your mail client to recognize Box emails and deliver them to your Inbox. 

If the email is still not found, please check your virus scan, Internet Service Provider, company's mail server, or firewall.

Please make sure that your email client is not blocking emails from

• box.com
• notify.box.com
• reply.box.com
• track.box.com

You may need to contact your IT department to assist you; please review this article: Troubleshooting Issues with Email Notifications. 

Hope it helps, and please let us know if you have questions.
