Ok so I cannot seem to figure this out.
My hotmail account I have setup to go into my messages.
However it seems when I delete anything in the messages app it doesn't delete on my account.
In fact most of the time it says it hasn't even been opened.
I have my BB with the newest OS for the 8130 and all my other internet apps work great.

Seems to be working correctly. There is no email sync using BIS (which I assume you are using).

ok, i wasnt sure on that.
for some reason i thought it would even delete them and so forth
