Is there a way to increase it and have more PMs stored? Mine is almost full. I already deleted the Sent items sometimes, when I got the notification of 90% full, but I think that after some more messages this won't be enough anymore. I'd be sorry to delete my messages though not all of them are 'important', and I'm worried about privacy if I download them on my computer.
Hope there is a way. If not, thank you however
