email problems


New Email
I am writing about two problems:

1. Recently, I med two women who are professors and have an email address ending in .edu Initially, I could email them. Now whenever I email them at the edu addresses, my emails to them bounce although I receive emails from them. My emails to them from my account do not bounce. Only when I email them from my live mail account does it bounce. I can email them from my live mail account to alternate email addresses they have but not to the ones ending in edu

2. After I have read some of the emails I receive in Live Mail, when I go to it to read it again, it says I cannot open it--and frequently I can't delete it either. Sometimes I can delete it later. What is this and how can it be rectified?
