Cannot Delete AWS Directory

Question

I want to delete an aws directory but when I try, it gives me this error:

An Error Has Occurred

Cannot delete the directory because it still has authorized applications. Please deregister the directory before proceeding.

As it has said in the error message, I have to deregister it to be able to delete it. However, the directory is not even registered! and the 'Deregister' command is grayed out:

I also went into the 'Applications' section (in the left pane) and found no application.

What's going on here?

Answer 1

This issue seems to be a shortcoming from Amazon. Amazon should have given me a proper error message. Anyway, I noticed that if I go to AWS Directory Service and try to delete the directory, it explains me the root of the issue:

So I went to AWS WorkDocs Service and deleted it:

Answer 2

I had the same issue. I checked WorkDocs and there were no sites that I could delete. I had to create a new site and then go through the steps of deleting and selecting delete the user directory.
