Windows Live Mail

Running Win 7  and for about two weeks I seem to be in a loop. To get into this community, I had to change my password for about the 20th time.  When I click on to Windows Live Mail it loads normally but will often again ask for a new log on, I just cancel it and then it will get new emails OR I get "Mail  We have noticed some unusual activity in your account.  Your action is needed to make sure no one else is using your account."  To continue click OK or have Cancel option.  If I click OK then go through the complete change password thing again, if I hit cancel then I can get my emails ok BUT I can't send any email.  I get a message that I must delete email with photos................. even though the email may not have a photo.  Any email that I have attempted to send goes to Outbox where it may or may not indicate a number.  When I close Windows Live Mail, then I will get message questioning if I want to send messages from Outbox - knowing that they will not send, just close it out.  Have gone through the Window Essential repair route with no changes.  Help will be appreciated.
