How to Set up Your Junk Email Options - EN

Written by: admin

This guide describes how to set up Junk E-mail Options and explains the spam indicators in email subjects.

Applicable to: Exchange Online mailbox users.

 

In Outlook, Emails marked as spam are automatically moved to the Junk Email folder.

For emails marked as spam, if confirmed to be legitimate communication emails, you may perform a temporary release or add them to the whitelist(Safe Senders List) on your own. If you cannot verify the legitimacy and security of an email, please contact IT for assistance in judgment.

 

Note: If you use the built-in Mail app on a Mac to send and receive emails, managing the whitelist (Safe Senders) and blacklist (Blocked Senders) is currently unavailable. To use these functions, please set them up via Outlook on the web.
