Forwarding Mail from resource

Hi everybody,

I was recently shown the following problem :
A user is accessing the mailbox of a resource as a proxy to forward mail to several colleagues. If the composed email is not send immediately and stays open for 30 seconds, GroupWise will AutoSave the mail and create files (c:\Documents and Settings\user\Local Settings\Application Data\Novell\GroupWise\) beginning with GWItemSave. That is working as designed, but these files will never be deleted automatically, so in my case there were already several dozens of files. If you proxy into a users mailbox, those files are deleted.
I 've already searched the forum without success, but I probably missed something.
Thanks in advance for your replys.
