DCOM errors on Server 2012 RDS server

I am getting several DCOM errors per day on a Server 2012 R2 RDS server. I believe these errors are being generated each time Office 2016 (Office365) is loaded.

This error, I believe, is leading to the server becoming unresponisive. This is the last error before we had to do a hard shutdown on the VM.

The server {0823B6F8-F499-4D5E-B885-EA9CB4F43B24} did not register with DCOM within the required timeout.

These occur regularly:

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{9BA05972-F6A8-11CF-A442-00A0C90A8F39}
 and APPID
{9BA05972-F6A8-11CF-A442-00A0C90A8F39}
 to the user DOMAIN\user SID (S-1-5-21-2276840340-2600592784-1026484717-10752) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

{9BA05972-F6A8-11CF-A442-00A0C90A8F39} points to ShellWindows and {8BC3F05E-D86B-11D0-A075-00C04FB68820} points to WMI.

This article (http://www.itexperience.net/2017/01/13/event-id-10016-fix-the-application-specific-permission-settings-do-not-grant-local-activation-permission-for-the-com-server-application-with-clsid/)  says to grant permission to the user that is generating the error. I am reluctant to do this because it seems to be every user that logs on to the terminal server.

Should I add the RDS user group? Leave it alone? Please advise.
