Change Base URL of Dynamics 365 Portals

A good news for portal users. With the latest Portal update, it is now possible to change the Base URL of a portal after it has been provisioned.

To change the base URL of the portal open you Portal administration through Office 365 login.




In the last screen above just scroll down to bottom and you will see a new tile – “Change base URL”


On Clicking it asks for a new sub-domain.



My initial URL was . I changed it

It will take a moment and then the portal will be restarted.

Then you will be able to browse the portal with the new URL.

Hope this helps!
