Sharing UI Flow Update
This suggestion is to update the UI/UX for sharing to be less confusing for users. When going through the process to share a file in OneDrive for Business, the blue "Send" button is enabled regardless of whether the user has added anyone's email addresses. This is also the case if the user picks "Everyone with existing access" then tries to hit "Send" with a message - assuming OneDrive will re-generate a message to everyone with existing access.
To improve this, the "Send" button should only really be enabled (clickable) if the user has successfully added valid e-mail addresses when sharing individually. For situations when they pick the everyone/existing users links, the blue "Send" button should be disabled entirely to avoid confusion. Instead, the "Copy Link" button should be highlighted as the only real option to share.

As an update/alternative flow - the ability to re-generate an e-mail to existing users should be provided so that content owners can "remind" or include an e-mail with a message for context.
