RE: How to change D365 crm url. I need to remove .crm.dynamics.com and add our company domain.
I agreed with Omar, you can't change the URL ".crm.dynamics.com" all regions has it on URL's " like Canada region "crm3.dynamics.com" EMEA region ".crm4.dynamics.com" but you can change the organization part and give friendly name.
-specify a descriptive for the address you will use to access your dynamics 365 application
-only letters and numbers are allowed in the url name and you can use - in the url like "sales-test.crm.dynamics.com" .
There shouldn't be any issue redirecting a url to the dynamics url.
create a webpage with desired URL and with an onload event with the following code:
window.location.href = "sales-test.crm.dynamics.com";
