With Citrix Cloud Gateway (Web Interface replacement) comes a new feature what looks a lot like Microsoft Outlook/Exchange “auto discover feature” . Also for Citrix, to make auto discovery work, you need to add DNS records to your (DMZ) DNS server (or third party DNS provider). This functionality is added to the new versions of Citrix Receiver.
It now asks you to enter an e-mail address or server address..
Not very handy if you are not using any of this.. for example, still using Web Interface 5.4.
Here’s a guide to disable the “Enter your work e-mail or server address” notification.
