Delete archived mails in the Doxis Outlook plug-in after a defined period of time

Currently, the only valid options for deletion after archiving are either to delete nothing or to delete the mail immediately from Outlook. Both have weaknesses in practice:

Our users have folders with assignments where automatic archiving is enabled. When they receive an email, they still want to work with it in Outlook, so immediate deletion is not an option. However, older emails are not needed so often, so it would be ideal to delete them from Outlook some time after they have been successfully archived in Doxis.

A setting that allows you to delay the deletion of emails after archiving (e.g. 3 or 6 months) would solve this issue.
