I use a hotmail address & quite often emails end up in the spam folder & I have to retrieve them. Any email with an attachment received has to be made "safe" before I can access the attachment
I think (as I learnt after losing some emails) that you can set the spam to be automatically deleted rather than placed in a separate folder, so this causes email to be lost.
Sometimes when I send to others from hotmail, they do not receive it. Some spam filters seem to automatically, or on request refuse email from web email systems
