Configure
Skype for Business
 for the
Presence
 service

Environments configured to use
Skype for Business
 on-premises that are using trusted application mode use the Unified Communications Managed API (UCMA) software for the
Presence
 service to communicate with the instant messaging server. Environments configured to use
Skype for Business
 on-premises that are using non-trusted application mode use Unified Communications Web API (UCWA) software for the
Presence
 service to communicate with the instant messaging server.
  1. In the
    BlackBerry Enterprise Mobility Server Dashboard
    , under
    BlackBerry Services Configuration
    , click
    Presence
    . 
  2. If necessary, click
    Service Account
     and type the login credentials for the
    BEMS
     service account.
  3. Click
    Skype for Business
    . The system queries the instant messaging server to verify that the appropriate
    BEMS
     instant messaging server topology is added. This can take a few moments to complete.
  4. Complete one of the following tasks:
    Instant messaging server in environment
    Task
    Skype for Business
     on-premises using trusted application mode
    Using this configuration, the
    Presence
     service is trusted by
    Skype for Business
     and can impersonate a user. End user authentication is not required on the device to view the presence status 
    1. Select the
      Skype for Business On-Premises
       check box.

      .  
    3. Beside the
      Application ID
       drop-down list, click

      . This step can take up to a minute to complete.
    4. In the
      Application ID
       drop-down list, select the app ID for
      Presence
       to use the correct configuration information registered with the
      Skype
       topology. For example,
      <
      appid_connect.mycompany.com
      >
      .
      If the drop-down list is empty, either the
      BEMS
       <
      instant messaging server type
      > topology is not set up correctly or the service account does not have permissions to query these settings.
    5. In the
      Application Endpoint
       drop-down list, select the appropriate endpoint for the
      Presence
       service to use when subscribing to a user's presence status in the
      Skype
       topology.
    Skype for Business
     on-premises using non-trusted application mode
    Using this configuration, the
    • Presence
       service is not trusted by
      Skype for Business
       and cannot impersonate a user. End user authentication on the device is required.
    • Presence
       service passes through the web proxy if it is defined but doesn't use the bypass list even if the
      Skype for Business
       servers are added to the bypass proxy list. In some cases, authentication to
      Skype for Business
       might fail. For more information on configuring the web proxy, see "Configure a web proxy server" in the BEMS-Core configuration content.

         servers in the environment.
      • Enter the default
        Skype for Business
         on-premises FQDN or the complete URL to the
        Skype for Business
         server for
        BEMS
         to use if autodiscovery is not enabled or fails. For example, http(s)://<
        FQDN_of_the Skype_front_end_pool
        >/Autodiscover/AutodiscoverService.svc/root/oauth/user.
  5. Verify the
    Entra

    • If you configured the
      Presence
       service for
      Skype for Business
       on-premises using trusted application mode, start the
      Good Technology Presence
       service. Make sure that you save the configuration in the Dashboard prior to starting the service.
    • If you configured the
      Presence
       service for
      Skype for Business
       on-premises using non-trusted application mode only, you do not need to start the
      Good Technology Presence
       service.
      Skype for Business
       on-premises using non-trusted application mode don't require the
      Presence
       service to view users' presence status. If you try to start the service, the following error message is displayed.
      Windows could not start the Good Technology Presence service on Local Computer. Error 5: Access denied
      .
    • If you configured the
      Presence
       service for
      Skype for Business
       on-premises using non-trusted application mode only, restart the
      Good Technology Common Services
       to enable the
      BEMS
       cache to use memory instead of Redis.
