Please tell me about the specifications for user deletion via provisioning

After a user is deleted from Entra ID (formerly Azure AD), their account remains in Teachme Biz for 30 days

For 30 days, the account will remain in Teachme Biz in the following state:

• Suspended (unable to log in)
• Alphanumeric characters automatically added to the account name

If you want to delete the account from Teachme Biz before 30 days have passed, manually "permanently delete" the user from the "Deleted users" screen in Entra ID (formerly Azure AD).

You can also suspend the account in Teachme Biz while keeping the user in Entra ID (formerly Azure AD)

Exclude the user from the "Teachme Biz" application in Entra ID (formerly Azure AD).

Folder administrators and manual owners are automatically transferred to the group administrator

Group administrators cannot be deleted through provisioning

If you want to delete a group administrator, change the administrator to another user in Teachme Biz first, then delete the user in Entra ID (formerly Azure AD).
