Sent PMs not going to Sent folder

I usually get responses to PMs, so I think they are all going out ok, but recent PMs are not showing up in my Sent folder which still contain 5 older sent items. Is there a setting I accidently changed?

In your profile use Edit Options. Make sure the box labeled Save a copy of sent messages in my Sent Items folder by defaultis checked.

Thanks. Don't know how I missed that.

You only get 50 total.

Actually, that limit is a lot larger when you have Premium Access.

This might be an older thread, sorry for bumping it. But I am having the same problem described.
It seems none of my PM's are going out.
Yes, I checked and i do have a checkmark in "Save a copy of sent messages in my Sent Items folder by default.
I was wondering why nobody was responding to my PM's. Well now I know, but the next question is, how can it be fixed?
Any administrators or moderators here? Can I get a little help?

I'm not getting email notices

Maybe you passed the limit and that's why you can't see the messages you sent?
