Helen from Dropbox here. Thanks for reaching out about your verification email.
If it’s not arriving in your inbox and you've already looked at Spam/Junk filters, this means that these are being blocked before they're arriving to their inbox.
In this case, I would recommend reaching out to your organisation's mail domain administrator for next steps.
You should be able to provide them with the email address of the sender (in this case "no-reply@dropbox.com") and the approximate time the message should be coming through (when you prompt that email to be sent), and they should be able to provide more information and the next steps on how to make sure these messages come through normally.
I hope this helps.
Best regards,
Helen
The Dropbox Team
