Using Dropbox with Yahoo Mail

What does linking my account to Yahoo Mail mean?

Dropbox has a built-in integration with Yahoo Mail, letting you:

  • Attach files directly from Dropbox
  • Attach large files (up to 150 MB) by uploading them to Dropbox first
  • Save email attachments directly to your Dropbox

This integration doesn't require you to sign in Dropbox. Instead, you only need to approve "linking" your Dropbox account with your Yahoo account. Then, when you first use Dropbox in Yahoo Mail, you'll see a screen asking you for permission to link your accounts.

By linking your Dropbox and Yahoo accounts, you'll be automatically signed in to your Dropbox account when you sign in to Yahoo Mail (and nowhere else).
