As a CRM developer, whenever I want to edit site map, I only having following two options available \tExport the sitemap and edit xml manually and reimport it again. \tUsing some third party tool First one requires very high technical skills and also there is a possibility of errors because of manual editing. Latter one is good option but it is not Microsoft supported. Good news is now you can edit sitemap from Dynamics 365 UI itself. Microsoft added it in December 2016 release. You can access it by using following steps. \tGo to \u201cSettings\u201d and click on \u201cCustomizations\u201d 2.Click on \u201cCustomize the system\u201d to open default solution. Alternatively, you can open any solution which can contain \u201cSite Map\u201d 3.Click on \u201cClient Extensions\u201d and Select \u201cSite Map\u201d and click on \u201cEdit\u201d button present under Component Type dropdown. 4.That\u2019s it, now you have built-in Site Map Editor Open and you can update Site Map. Don\u2019t forget to publish your changes otherwise, it will not reflect on Dynamics 365 UI.
