You must define at least one category to create a mapping.
You do not need to define categories for journal archiving because you can use the applicable default category.
If a category is being used for a configuration, you cannot delete the category.
Let's assume you want to define your own category for a mapping.
This is how it works
Open the Configuration feature from the start page and navigate to E-mails in the Document management category.
Select the entry Categories under E-mail management.
In the category overview, choose the context action Create new category.
Enter a unique name for the category and save your entries.
