We're using SharePoint 2013 internally and use a third-party provider for Exchange. This presents a problem when using Exchange calendar overlays in SharePoint as they're not on the same domain.

Is it possible to supply separate (401 challenge) credentials for the Exchange OWA and EWS URLs? Or does anyone else have a workaround for this type of scenario?
