title: EWS intermittent "Unable to connect to the remote server" - Works 99% of the time
body: <p>I have a c# app that exports data from the database to the user's Exchange Calendar, using Microsoft.Exchange.WebServices (15.0.0.0). My app is DotNet 4.5.2 and I use Visual Studio 2013.</p>
  
  <p>The app has been working fine for a year, and even now works 95% of the time. The app runs constantly on machine that I am logged into and monitor.  This is a low volume process, perhaps 50 items get exported per day at most.</p>
  
  <p>Every couple of days, the program will give this error:
  "The request failed. Unable to connect to the remote server"
  when the app is attempting to create an EWS connection to the server.</p>
  
  <p>It will do this for maybe 10-20 items. So I shut it down, run it again, and it works perfectly fine on all the records that failed before.</p>
  
  <p>This is my first EWS app, but I've been programming 30+ years and do have somewhat little knowledge of internet based apps.</p>
  
  <p>Any helpful information or suggestions would be greatly appreciated!
  Thank you kind people!</p>
