Microsoft Outlook is the campus-wide email system for all SVSU students, employees, and alumni. The server implements a spam-content filter that places known spam messages into quarantine holding. Access the list of messages held in quarantine at https://security.microsoft.com/quarantine OR spamcheck.svsu.edu.
If a message has been held in quarantine, it has not even made it into your Inbox. You do not need to use the Block Sender option to futher protect your account. Blocked senders are domains and people you don't want to receive email messages to your Inbox folder. Messages received from any email address or domain in your blocked senders list are sent directly to your Junk Email folder.
