Thanks for listing the mailbox stats.
Yes, I would suggest you go ahead and split InBox and OutBox into folders of up to 5,000 items (4,900 is a safer maximum). If you find problems with any of the new folders, try splitting them into folders which are smaller still.
Several customers have reported success with this technique. I hope this helps.
By the way, which version of GroupWise are you running?
Kind regards,
