PPT sharing is not working externally RRS feed

  • Question

  • Hi,

    We have deployed Office Web app server to share Powerpoint slides with SFB Enterprise Pool, it is working fine internally but when we are trying to share any PPT with federated partner it gives error "We can't connect to the server for presenting right now, reference error code 141". We are using F5 load balancer to publish office web app services.

    For Entrie PPT sharing process what is the role of Edge Server ?

  • Hi Deep,

    I dont think EDGE is involved in the OWA(WAC), external access,

    You need to troubleshoot from firewall, Load balancer and Reverse proxy,

    The below article might help how to troubleshoot further.

    For skype for business reverse proxy  

    when a Skype for Business Edge Server is introduced and thus a reverse proxy solution is needed then this configuration will be revisited to provide for external access.  As this server handles only HTTPS (TCP 443) requests then it is not a role that is handled by the Edge Server, but must be published through a supported reverse proxy model in the same way that the SfB Front End server web services will be.

  • HI,

    We are facing same issue as mentioned in below article ;

    I guess it uses WebConf service during sharing PPT externally.

  • Please make sure that your organization enabled for external access for OWA.

    If external access enabled ,

    I suggest to use fiddler to check the URL redirection and see where is lag,

  • Jin,

    WAC uses the reverse proxy over port 443. Do you have a public certificate on the reverse proxy for WAC services?

  • Hi JinDeep,

    Welcome to post in our forum.

    The Reverse Proxy is used for meeting content externally, so please try to check the configuration of your reverse proxy.

    The web conferencing edge service was configured to use port 444 , make sure the port 444 if open on your external firewall.

    Here is a similar case for your reference

    Hope this helpful to you.

  • Hello,

    Web conferencing edge service is configured to use port 444 and this port is opened on external FW.

    I would like to inform you here we are running under co-existence phase where Lync 2013 and Skype for Business are parallel running using same Topology.At present Edge Services are being used through Lync 2013 Edge Server which is hosted on another datacenter and Reverse proxy is configured on another datacenter where we have whole SFB Servers including Office Wep Server.

    Port 444 is opened on external FW where Edge servers are placed and hosting services.But from other Datacenter which has its own external FW and reverse proxy configured to host Office web app services, only port 443 is allowed.

  • Hi,

    Please suggest if there is any article which describe about complete routing of Office Web app externally.I like to understand if there is any correlation with Edge services with Office Web app functionality.
