Azure Provisioning - Oops - Provisioned everything!

[Jennifer Osborn]

In re-setting up the user provisioning (in a new Azure Atlassian Cloud app) I apparently managed to sync everything from AD, including shared mailbox "users," other non-staff user accounts and every group in the directory.  Gak. Shake-fist.

The question now is - how do I effectively REMOVE all of this?  (cleanup on Aisle 8, please)

I can manually remove groups - a pita, but do-able.  But I can't seem to remove users - they're all "managed by my identity provider." 

If I  nuke the App in Azure AD and remove the directory in Atlassian Access, will that allow me to remove all of this excess baggage I didn't want/mean to add?

FWIW - I set up the app to include only a single group with 1 user. Yet, I managed to slurp in it all. 

Hrumph for learning the hard way. Thanks in advance for your insights.
