Error sending email notifications to office 365

[mfoley14]

We are not able to send email notifications from Veeam to Office 365. When attempting to send a test email we receive the following error. "Unable to connect to SMPT server because of invalid credentials or connection settings." I know its not an issue with the credentials, I am successfully able to log into the account we use email and can send and receive email on that account with no issue. Also tried other accounts. using smtp.office365.com for the smtp server. With port 587. Any help would be greatly appreciated.
