Well I have come across this problem, We have Netware 6 no SP installed.
Groupwise 5.5 to service packs installed.
Recently I have asked users to archive emails to their local PC's it was going well but recently Groupwise is not freeing up disk space from archived emails on the MAIL volume..
it is a 12gb drive it has only 530mb free.
How would I need to reclaim more space from the volume.
HOwever if I Check through the web interface and Volumes.. it says it has 2,097,991 mbytes free whats going on.
It is a NSS Volume I was thinking of running the NSS tools diagnostics on the volume would that be a good Idea..
