Storage Memory Low

[Brutus3200]

I did everything you guys said with the sprint tech. I was on phone for 4 hours yesterday. I deleted all cache and that freed up about 10 meg. Thats the thing, where do you find old emails with all attatchments stored? I cant find them? I let the sprint guy go thru letmein and search on file explorer as well and he couldnt find them. When you add up all the folders on the phone its only 23 meg. So where is the other 266 meg being stored? We couldnt figure it out so I had to do a hard reset. I did have all the message and attatchments going to sdcard. Now for some reason after hard reset I cannot get my email to load on phone. I typed in the account and password like before and it never sends or receives anything.
