Have Windows 7 and Live Mail was created Oct. 30, 2010 when computer was purchased.  Live Mail has a Modified date of July 10, 2013.  Have always used the Live Mail icon at bottom of desktop which would show my email address and prompted for my email password.

June 13, 2014, I brought up my email and was just about to click on the newest one in the Inbox when I saw a bolt of lightening out the window.  Yes, a storm was just starting, but was anxious to see the email - stupid.  The power went off for a second, a black screen with white print asked how I wanted to reboot the computer.  I chose the highlighted choice, which I think said "normal".  The computer came back up and all looked find until I clicked the Live Mail icon.

Could only get "Quick View".  It never displayed my email address and didn't prompt for my password, yet it said it was "online" in the lowest right corner of the screen.  My regular folders weren't there, and the ones that were there were empty.  I used Internet Explorer to get to the optimum.net site to log into my email from there.  My Inbox there is ok.  The Sent folder only has a few items, which must be because I sent them from the optimum site, not my Live Mail.

To get support, I had to create a Microsoft account.  No answer received, but 48 hours aren't up yet.  I brought the computer to the place I bought it and using my MS account, my optimum email address was added, and we turned off the MS account window from popping up.  Now my Live Mail icon acts like it did before the storm.  The Inbox is ok, my contact info is ok,  but the SENT folder is empty.  Since I've been looking for a job for over a year, I need those important Sent emails.

Just tried sending an email to see if new ones will be saved (all settings are ok to do that).  It won't let me send emails.  Got this error message:

"The message could not be sent because the server rejected the sender's email address.  The sender's email address was '....'".  It correctly showed my email address.   It also showed:  Server Error - 530.   Server Response: 530 5.7.0 No AUTH command has been given.  Server: 'mail.optonline.net'

Windows Live Mail Error ID 0x800CCC78     Protocol: SMTP   Port 587  Secure(SSL):No

The mail properties are:  Incoming POP3 server,  Incoming Mail - mail.optonline.net,   Outgoing mail (SMTP) - mail.optonline.net,  Incoming Mail Server - username (and it does have mine), and the radio button is set for 'Log on using clear text authentication.   Security = Algorithm 3DES.  Advanced has Outgoing Mail (SMTP) 587, Incoming Mail (POP#) 110.

Sorry for the long description, but I want to provide info so the problems I'm having are not misinterpreted.   I need to be able to send emails, and I hope I can get my "sent" emails back.

Thanks
