how long do attachments stay on phone/server? BIS

[CableGuy711]

I pop my mail from my personal isp's email

i noticed that i cant open my attachments from 2 weeks ago
but i can open one from 3 days ago.....


neither of these msgs are still on my isp's email server.

so where are the attachments stored? on the BIS server? and if so how long?
