When I delete message in my hotmail account my new Curve does not delete them from the inbox even after 12 hrs. If I delete on the Curve (mailbox & Handheld) it works fine. I get new emails promptly. I went online & delete & re-setup the email account on BB site, doesn't seem to have fixed it.
When I get a email notification on my curve, I read it and then delete it. Once I got home from work today I opened my hotmail account online and all the ones I deleted on my curve are still in my inbox on the computer.
