O365 Dynamics - Port Usage

(0) ShareShare
ReportReport
Posted on by

Hello,

We have an application that uses XRM.Tooling to connect to Dynamics O365  (cloud version) via  connection string.

The application just matches some fields on a Dynamics entity.

What ports are used in this process. I am quite certain that this is only port 443. Can anyone verify this?

Thanks in advance.

    Hi vanKjeassel  , 

    The URL can use http or https protocol, and the port is optional. The default port is 80 for the http protocol and 443 for the https protocol. The server URL is typically in the format https://<organization-name>.crm.dynamics.com

    more information check:
