You might consider trying Windows Live Mail
to see if it may work better for you instead.
It supports Pop3, IMAP, HTTP website (EX: Hotmail) email, and is a lot more stable. Plus, WLM will minimize to a tray bar icon, checks spelling as you type messages, and has a separate Inbox for each email account. WLM will automatically import Windows Mail messages, accounts, and settings into it. Contacts
will have to be manually imported from within WLM. (Tools, Contacts, File, Import, Address book for current Windows User.) To see the Menu bar
, press ALT+M and check "Show all menus".
