For inviting existing contact records as user of the portal we can follow the below steps.
Open an existing contact record and click on Create Invitation button
This creates the invitation record along with the invitation code.
Select and run the Send Invitation workflow.
The steps for the workflow are as below.
The contact\user receives the link for the confirmation
Clicking on the link opens the portal wherein user\contact can redeem the Invitation Code and Register.
User can set up username and password during registration.
Once registered user can access the portal and update the profile further and can also change the password, email etc.
The Contact record in CRM gets updated accordingly.
Hope it helps..

Hi Nashant, the invitation code does not generate automaticaly in my D365 (online) environment. Any idea on that?

That’s due to the scope of the send email Workflow being set at User rather than Organisation.

Hi Nashant,
I’ve followed the steps mentioned above and I was able to send the invitation code successfully. But when I try to register the code (I entered the required username and password) and click Submit, nothing happens. No error messages or anything to indicate the result of the registration. Am I missing something?
Appreciate your help. 🙂
