Hi Charles,
There is unfortunately no way to export the user list to obtain a list of users whose accounts are disabled, although this should only be a temporary state between them being deactivated in Azure and the account being completely removed from the user list.
You can now export the user list from the "Directory Users" page, and also upload a list of accounts which are to be deleted, however. Further details are available in our documentation: https://helpx.adobe.com/enterprise/using/manage-directory-users.html#permanently-delete-users
I hope this is useful,
Sincerely,
Dom
