I have a VLM-200 to load balance Client Access traffic to my Exchange 2010 environment.
Before we deployed our Kemp loadbalancer we were using Microsofts software loadbalancer. Back then i could access ECP via OWA without being prompted for credentials. When I do this now when we switched to a Kemp Loadbalancer i receive following message: (Translated from danish) "Your session is expired. To protect your account from unauthorized access, the access to your mailbox is closed after a period without activity. Insert your username and pasword again." After inserting credentials again i receive the same message. The strange thing is that this works from external networks. I use the same URLs for both internal and external access. I have configured the loadbalancer for SSL offloading.
Thanks in advance
