[SOLVED] iPhone email disappears

[mek1]

Very strange, here's some iPhone (2.1) screen caps of what's going on.

On refresh emails disappear and I'm not sure why.

On the left is my inbox on 11/03/08, on the right is 11/04/08.
I did not delete anything from the inbox, in fact on my testing laptops (outlook w/ connector) and webmail there's plenty in the inbox.

Has anyone else had this happen?

Withing Settings->Mail, Contacts, Calendar->Account what do you have Mail days to sync set to ?

uxbod,

It was set to 3 days.

Unlike the pop accounts I'm used to, the exchange account was removing anything older than 3 days.

User error.

thanks!
