We're in the process of implementing Unity for a security conscious customer. There's a firewall sitting between the Unity and Exchange server. We have problems with the Notify module in that after 60 minutes the authentication appears to fail and notifications fail. We've temporarily got around it by scheduling a restart of the AvNotifierMgr service every 55 minutes.
It looks like the firewall is dropping the connection after 60 minutes.
Does anyone know what the default "idle"time is on the Unity, or where this can be changed?
Has anyone seen this fault before and shed some light on a better solution than restarting services?
