Hello,
It should not take that long to download an attachment unless you happen to be on a dial-up connection. More likely you have a problem with your inbox or you have an Outlook Express setting that needs a change. In Outlook Express you can try unchecking the option for
Do not allow attachments to be saved or opened that could potentially be a virus. To find this option to to the
Tools menu and select
Options, and then go to the
Security tab.

Do you have an alternate way to check the e-mail account? Is it possible to check it from a webmail web page or with another e-mail program such as Mozilla Thunderbird? This may allow you to fix the account directly by reading or deleting a problem messages, or getting around a problem with Outlook Express by downloading the problem e-mails with a different e-mail client.
