We apologize for not getting this information out earlier, but the in-game email system only stores messages for 30 days. This information wasn't communicated to the team and we failed to provide it to you or the CS team.

 

If you want to store extra items in the game, your best option is to create an ALT character on the same server and email those items to him/her. That gives you an additional 100 Inventory slots to use, along with that character's Code Archive.
