Hi,
We have setup our exchange server with WAF, laatly when check the WAF logs we see status code 401 and 502 for the url that we use for our outlook anywhere and activesync, what this means? some times I hear that some of our users lost thier connection with exchange server and then in short time connection restablish. is this issue has something to do with ststuscode 401 and 502?
