Trying to delete Active Directory but getting error's

Question

Hi There, 
I am trying to delete an Active Directory that I have. I have removed all subscriptions from this Active Directory but now I get the message:
Directory contains one or more applications that were added by a user or administrator.
Under the Active Directory, I have no applications (it used to have applications and I have since removed them).
I don't have any other subscriptions tied to this Active Directory. It could have been used for an Office 365 trial quite a few years ago.
How can I remove this? Tried almost everything.
Thanks

Hello,
A Global Administrator can delete an Azure AD directory from the Azure Management Portal. When a directory is deleted, all resources contained in the directory are also deleted; so you should be sure you don’t need the directory before you delete it.
ERROR:  Directory has one or more applications
If you get this error message you may have applications associated with the directory, in order to proceed with the deletion of the directory you must ensure these are removed.
If you select the Applications pane within Azure Active Directory check the applications, and if they are not required then proceed with deleting them. If no applications are visible then you may find that you have ‘hidden’ applications that are not yet
exposed via the UI.
In order to delete this, you will need to use Azure Active Directory PowerShell module. You can download this (Manage Azure AD using Windows PowerShell)
Once you have downloaded the required components and successfully installed them go ahead and launch a Powershell Console
Connect -MsolService
Enter your global admin credentials {example:
[email protected]}
It is important to note here that you wont be able to login using a Microsoft Account aka Live ID and so if this is the only identity you have. create a work account aka organizational account in the directory first to perform this action which you can
delete once finished.
Get -MsolServicePrincipal | Select DisplayName
This will then show you what applications you have listed, some of which are require and won’t be able to be removed. if you don’t need any of the applications listed you can go ahead and remove them
Get -MsolServicePrincipal | Remove-MsolServicePrincipal
NOTE:
You will find that some error (red text will be displayed) ignore that, those ones are service side service principals but they are white-listed and the deletion will work with them present.
If this then fails, take a look at the PowerShell MSONLINE Log Files and if you still need further guidance, ensure to attach that to the support incident as it is super helpful to the support engineering teams when investigating the problem your having.
These files can be found “C:\Users\%username%\AppData\Local\Microsoft\Office365\Powershell\”
