We have received notice from Microsoft about a possible zero day threat to their Exchange Server platform, which we have investigated and therefore will apply to our Hosted Exchange solutions.
As the systems are redundant, we expect to patch without any downtime on client side, whereto some Outlook clients needs to renegotiate connection, should they be connect to the CAS array being patched, during the patch window.
Outlook clients should automatically reconnect upon connection error and be sent to the secondary CAS array during the emergency patch window being performed.
We will immediately restore the patched servers, should they leave the Exchange solution become unresponsive upon being patched.
