Someone please explain this to me with a relevant link because I can't seem to find any.

Auto-archive settings are set to archive mail 15 days old into a local folder on the local machine where the client is installed.

Does the groupwise 8.0.3 client auto-archive only read mail or all mail? I've been having this issue where suddenly all the unread mail is popping back up into the mailbox of the user, whereas before it used to be archived.

The user's PO is also archived by an external program (gwava retain) so I want to know what kind of archiving does the client perform when you select auto-archive and where can you modify these settings if there is such an option.

This is really giving me a headache.
