If you use Office 365, the settings should be:


Host Name/Address:

Port Number:                587

Use SSL:                Unchecked

Use TLS:                Checked

Authentication method:        AUTH LOGIN    (Automatic may also work)

Username :                (your Office365 E-mail address)

Password :                (your Office365 password)

Also note that if you're using MS Exchange, they will be disabling SMTP but you may be able to re-enable it.  Try this for information:
