Federated Office 365 - Creation of generic mailboxes with licenses on O365

On my test platform Office 365 trial and Okta developer site,  
Office 365 is federated and provisioning to Okta.   Not using windows AD.

How do I create an Office 365 generic mailbox which has a license, the mailbox will delegated to Office 365 users for access.
I don't want this to be on Okta as no one will access it directly.

When I create the user in Office 365 and select the domain that has been federated it prompts:

"Error you can't add users to a federated domain.  Select a different domain and try again."

Are there any ways of creating this account without unfederating it then create this on Office 365 and then federating it?

Thanks
Andy

Thanks Andy,

Ok great, once you create the *.onmicrosoft.com account you can add a new SMTP address using your federated domain suffix and make that your default email address. This would keep the account within your Office 365 tenant with an active mailbox using your federated domain suffix.

Hi Andy

Thanks for the community participation. Are you able to add a new user to your Office 365 tenant by selecting the "onmicrosoft" domain suffix when providing a username? I've provided a print screen to demonstrate the area I'm referencing.

Hi Darron,

Yes, I am able to create the account on the *.onmicrosoft.com domain but not the federated one.

Hi. Would it be possible for you to briefly describe the setup within Okta required to achieve this? We need to allocate users access to both a unique/personal AND a generic mailbox. Many thanks.
