Hi Steve,

i have an idea how to figure out whats going wrong...

when HTTP_REQUEST {
    if { [catch {
         Lets try this...

                pool /Common/AP_EXT_O365_Exchange_Online_Direct
            } elseif { [class match [IP::client_addr] equals "O365_Exchange_Online_IPv4" ] != [class match [getfield [IP::client_addr] "%" 1] equals "O365_Exchange_Online_IPv4" ] } then {
                log local0.debug "Reminder to myself the other region uses Route Domain suffixes..."
            }
        }

    }] } then {
         Something strange is going on and has crashed TCL
        log local0.debug "Extended Error: [subst "\$::errorInfo"]"
    }
}

Cheers, Kai
