webmail has been working fine for years until this week, now internal webmail works without problem but external webmail is giving a incorrect cert, and the cert that is incorrect is from a Vigor router/ draytek
we do use a draytek router in the office just as a Wi-Fi point,
How can exchange suddenly start to use a cert from the router and how do I fix it please, The correct cert is still in place and is in date and hasn't been changed in anyway
