My sent messages are set to be saved. There are some saved but it appears they drop off over time. Is there a way to keep sent messages indefinitely?

When I signed on to my email account this morning, all of the favorites were gone.  The only unusual event that I can think of

is that when I went to shut the computer off last night, I receive the message regarding a "windows critical update".  I tried

called because I have an MSN Premium acct., but no one there seemed to be able to help,  I have had very good service in

the past, but this appears to be too much of a challenge.  It's hard to believe that it is not somewhere on the hard drive.

I want to search for an email I received in Dec/Jan 2011/12 to retrieve an address....there seems to be no
way of going back to the past emails...what do I have to do to search for an email

This started about 10 days ago and I have no idea why.  My phone provider has checked the settings and says everything seems fine but I keep getting the message 'cannot connect to mail server to verify your account' when I have deleted the account and try to set it back up.  I have download the Hotmail App but I preferred the old way as my inbox is now getting too full on my phone as I cannot deal with everything immediately.  How do I get it back the way it was. 
I can delete emails in my Inbox one by one but this is too long.  I want to delete  20 emails in one go. Is there a quick way to delete 20 Inbox emails from Windows Live Mail?  Would be obliged if you knew and let me know. Thanks. U.Kuran
