Security Risks of Out-of-Office Replies

Learn why out-of-office replies pose security risks, including phishing vulnerabilities and email loops, leading to provider restrictions.

Why are out-of-office replies considered a security risk?

Out-of-office replies are considered a security risk because they can be exploited by hackers for phishing attacks and can create email loops. These replies can inadvertently reveal when someone is not available, which can be used to time phishing attempts more effectively.

Additionally, if not properly managed, out-of-office replies can lead to email loops, where automated responses continuously trigger each other. This is why many email providers restrict or suppress these replies, especially to automated systems like Zendesk.
