I've had a lot of grief from a few users' Exchange doing it (likely as part of some anti phishing plugin of sorts), to the point we changed validation links from one time to sort lived.
Don't know why you are downvoted. Many corporations and institutions employ sandboxes to check mails and the links contained in them. This is a standard security practice by now.
So a link that is only valid once would be affected. Restricting the validity by time is a good way to solve this while still maintaining decent security.
