I use Hotmail account for my business & I think the mailbox is getting  very heavy.

sometimes I can only see the subject list, but no contents in the mail

sometimes the messages keeps blinking & cannot type or read anything

I arrange my mails per subject thread.  Sometimes, particularly few senders, when they send in a message, it do not appear at top of list.  I do not really know where it is, but just need to use the view Unread command.

As I use hotmail for business, I am afraid if one day my mail box crashes, then it wl be disaster.  Pls adv if I can back up my mails somewhere & how

thank you
