Categorized Mail Folder

[Guest]

Under my search folders there is a folder called Categorized Mail that is
greyed out and when you try to click on it you receive the error: The
operation failed. Is there a way to remove it and what is it for anyway?

hat is not a folder that Outlook creates by default. Do you have any add-ins
that would be responsible for the folder? If you create a new mail profile,
can you delete the folder?
