Office Online server not work with IIS ARR RRS feed

  • Question

  • Hi Support,

    We have an office online server and it works on internal network. However, it does not works when a user tries to access it from external network.

    We are using Windows Server 2016 IIS ARR to publish exchange 2016 and also Office online server. Exchange services (owa, autodiscover, activesync, etc.) works fine, but the office online services failed.  

    The rules setting is regular expression ((?:^en-us/|^hosting/|^m/|^o/|^oh/|^op/|^p/|^we/|^wv/|^x/).*). After open the documents, it will show this error:


    The testing link can access normally.

    Any ideas?

    Best Regards



    Andy Chong
