There is a basic Calendar clean-up function and there are some views or search options that can be used to clean up the mailbox but it involves too many distinct steps to achieve the goal. There is no easy-to-use tool to be more efficient. This tool is not about "archiving". It's about "deleting" documents.
The tool is a single window to select what to delete (first level of checkboxes) : sent or received emails from/to a Person, a date/time range, take into account foldered emails or not, words in Subject, include calendar items, by size range, save attachments first, in which folder,... All these criterias are then combined with an "AND" operator.
Then display the search results and ask for a confirmation for the deletion.
Criterias are saved for the next time the tool is used by a user in this mailbox.
