We have released a security update for Adaxes 2018.2, 2019.1, and 2019.2. What does it do? It replaces basic authentication for Exchange Online connections with a more secure method. Why? Microsoft will no longer support basic authentication come October 2020.
Why do I need to update? Your Adaxes won’t be able to connect to Exchange Online after October if you don’t update. What if I have Adaxes 2018.1 or older? This update is not available for Adaxes 2018.1 and older, so you need to upgrade to the latest version.
