Well, sushubh seems to have increased it to 500 for all groups, but even then eventually it will fill up.A more permanent solution, is to go to your "My Controls" & click "Archive Messages" & send upto 50 messages at a time, in HTML format, to your mailbox, after which u can save it on PC & delete from mailbox (or keep in mailbox itself).Believe me, I got the same prob (on another forum), & after my PM box capacity was increased, I'm struggling even more now, with organizing msgs in categories & sending 50 at a time to mail & whatnot... to clear it out to accept new msgs.And then a week or 2 later, all of 1000 PM clogging the message center & I'm back to cleaning it out & prioritising which HAS to be kept, which deleted, etc....The point i seek to make, is that increasing capacity is not a solution, it increases problems for all - the member, admin & the db.
