Hello,

Can you clarify why we need to patch an Exchange hybrid only use for management purpose ?

( We are using multiple hybrid servers for many customers without any inbound connection from internet. )

So the exploit cannot be run from internet.

In this situation I understand that I need to patch but not in an emergency way ( as it was the case in March).

Thanks for your clarification.
