    Default waf in front of exch owa

    Just wondering why it seems not to work in front of an exchange server.
    I've put the waf in front of my exch server and when i add the internal ip range to the allow list, all is good. But if i don't I get an err 400 like the one below and in the owa I get a "Error: Your request can't be completed right now. Please try again later."

    Whats going wrong?

    Thanks for reporting this issue. This particular rule ID seems to generate false positives in other circumstances as well so we are investigating a solution. Meanwhile we are prioritizing this issue as I see this as a common case considering the popularity of MS Exchange Server.
