When I try to write an email, Outlook quits and says that it encountered a problem and needs to close.  I can still receive email, reply and forward it, but cannot write an email.

Hello

I just read up on sure signs of a hacker and yes that must be why my computer is acting weird. I was going to click on an email from someone I know and accidently I opened this email from a suspecting hacker. I have the email address and does this help to identify them or not? By the way, my computer is running slower, programs are opening that I never opened, error reports showing up alot and browsers seem frozen when I try to close them. These are some of the signs I'm experiencing. I do scan my computer often and remove threats.

 

Thank you

Hello

(removed for privacy)    is a  new hotmail address of mine.  It accepted emails at first, but now it wouldn't . It sends them back to the sender with a message that it can't be sent to my new hotmail address. Will you please fix the problem and let me know it  is fixed by sending an email to: (removed for privacy).   Thank you.
On random occasions outlook will resend thousands of emails to my inbox.  I don't know how to stop this.  It is very frustrating and requires me to go back into outlook and delete these duplicate emails.  I have Microsoft Office Mac 2011 home and business.  Any help would be appreciative.
