Hi Igor,

I am not sure if there could be a viable way allowing to add an external user to Azure AD.

When looking in K2 Cloud documentation, there isn’t a Workflow wizard step with capability to add an external user to AAD. See below K2 Cloud AAD Workflow wizard capabilities link.

Good day Igor

The 1st option to achieve this is to manually add an user to your Azure AD, please follow this link: https://docs.microsoft.com/en-us/azure/active-directory/b2b/add-users-administrator for more information.

Second option would be to create a workflow web API that will allow you to pragrammatically add a user to Azure AD please refer to this link: https://stackoverflow.com/questions/44756742/how-to-create-azure-ad-user-programmatically on how to go about adding a user pragrammatically to Azure AD using c#

Please use thiese link:
