Outlook prompts after move to new load balancer

Tuesday, December 9, 2014

What is happening? Some users are getting Outlook prompts warning them about settings coming from a redirected location.

Why is this happening? Exchange/Connect was moved to a new network load balancer on Monday morning. The new network load balancer has a different IP address than the previous network switch. Outlook notices that the Exchange configuration location (autodiscover) has changed and is prompting you to accept this “new” source for your Outlook settings.

What should users do? It is safe (and appropriate) to allow this and future prompts for the website https://autodiscover.uwaterloo.ca/autodiscover/autodiscover.xml.

More details and screenshots, if interested:

AutoDiscovery is the process that Outlook uses to determine where Exchange servers are located within the organization. It assists in client configuration and setup. By default, Outlook checks a series of website locations based on your @uwaterloo.ca email address.  The address https://autodiscover.uwaterloo.ca has always been configured to resolve to the network load balancer that services Connect. After Monday’s move of Connect to use the new load balancer, Outlook detected the move and warns you of the change. As long as the prompt has https://autodiscover.uwaterloo.ca/autodiscover/autodiscover.xml as the source, it is safe to allow Outlook to retrieve configuration information from this source. This prompt will only occur on clients with previous Outlook configurations (new profiles will not be affected). Subsequent prompts can be suppressed by checking the option “Don’t ask me about this website again” (Windows) or “Always use my response for this server” (Mac) when allowing the update.

Sample Prompts:

Windows prompt.

Mac prompt.
