Exchange 2016 APM outlook anywhere

if i change the autodiscover auth to basic and add this irule and then configure outlook with an account. it look like it works but after the restart of outlook ,i get an error : the connection to microsoft exchange is unavalabile

irule:

priority 1 when HTTP_REQUEST { set is_disabled 0 switch -glob [string tolower [HTTP::path]] { "/ews/mrsproxy.svc" - "/ews/exchange.asmx/wssecurity" { set is_disabled 1 set path [HTTP::path] ACCESS::disable HTTP::path _disable-$path pool Ex2016FromInternet_ews_pool7 } "/autodiscover/autodiscover.svc/wssecurity" - "/autodiscover/autodiscover.svc" { set is_disabled 1 set path [HTTP::path] ACCESS::disable HTTP::path _disable-$path pool Ex2016FromInternet_ad_pool7 } } } when HTTP_REQUEST_RELEASE { if { [info exists is_disabled] && $is_disabled == 0 } { return } if { [info exists path] } { HTTP::path $path unset is_disabled unset path } }
