The Outlook safe senders list contains domain names for which email will not be moved to your Junk E-mail folder. By default, email addresses in your Outlook contacts are considered safe senders by the Junk E-mail Filter. However, when you send a message to a person or organization that is not an Outlook contact, the recipient's email address does not get added to the Safe Senders List. This means that when the recipient replies to your message, their reply might be moved to your Junk E-Mail folder.

To make sure that email from the Columbia Business School community is not sent to your Junk E-mail folder, even if they are not an Outlook contact of yours, please do the following:
