Summary

Customers configuring outbound DNS resolution from Mendix apps to internal on-prem services were hitting Azure deny-assignment errors when trying to create a Private DNS zone (and its record sets) directly inside the Mendix on Azure Managed Resource Group. The existing docs mentioned creating/using a Private DNS zone as an option, but did not explain this restriction or where the zone should actually live.

This PR expands that section to clarify: create the Private DNS zone in a resource group you control, outside the Managed Resource Group, then link it to the Mendix vNet via a virtual network link. A cross-link is also added from the support/customization page.

Changes

  • content/en/docs/deployment/mx-azure/configuration/mx-azure-network-interconnecting-networks.md: expanded the "DNS Name Resolution towards Resources in Other Networks" section into two clearly labeled options, with step-by-step instructions and the deny-assignment rationale for Option 1.
  • content/en/docs/deployment/mx-azure/mx-azure-support.md: added a cross-link bullet to the connectivity customization list.

Test plan

  • Review rendered content for accuracy and tone
  • Confirm anchor links (#name-resolution-dns-override, #dns-zone-outside-mrg) resolve correctly

@katarzyna-koltun-mx this can be merged immediately once approved.

…solution

Customers hit deny-assignment errors when trying to create Private DNS
zones/records directly inside the Managed Resource Group. Clarify that
the zone should instead be created in a resource group the customer
controls and linked to the Mendix vNet via a virtual network link.
