I have tested several emails to ( Outllook.com, Hotmail, MSN, ECT). They all say they where delivered okay, but I never receive the emails from my organization.  I work at a school and many parents are not getting our emails. Is there a way to find out why on our end it says delivered, but when I open the Microsoft mailbox it never shows the emails? I have checked junk, deleted and all areas and don't find the email. The only way I can get the email to come through on my personal account (outlook) was to add a contact for the email address. Any suggestions on where to go to ensure my emails go through, because they are legitimate?

Thanks for any help!
