The influx of spam messages in your Inbox has become a prevalent issue, causing disruption and distraction. It’s estimated that these spam emails now constitute roughly 50% of all email traffic. In today’s digital landscape, spam messages have emerged as a significant contributor to cyberattacks through unfiltered emails.
Spam senders employ sophisticated methods to attach viruses and malware to emails, putting your entire system at risk with a single click. Microsoft offers Exchange Online Protection as a safeguard, shielding your email accounts from the constant influx of spam and unwanted mail, ensuring filtered content reaches your inbox.
EOP, or Exchange Online Protection, is Microsoft’s cloud-based email filtering service. Its primary purpose is to safeguard Exchange account emails by detecting and neutralizing spam and malware links. EOP is an integral part of the Microsoft Office 365 subscription plan.
EOP works in a way to keep your emails safe and protected from various malware or ransomware emails. It helps in keeping the Inbox clean by filtering out spam and phishing emails. Thus, it helps you protect Office 365 data.
Let’s elaborate on the working of EOP.
Emails follow a path through multiple routers and mail servers before arriving in your Inbox. If your email server is powered by Exchange Online, it operates as a virtual mail server distributed across Microsoft’s cloud-based data centers. Typically, alongside legitimate emails, spam messages may also attempt delivery. This is where the role of Exchange Online Protection becomes crucial.
EOP conducts a swift evaluation of the sender’s reputation, including their IP address, domain name, and keywords in the title or message text. Following this verification, it cross-references the data with predefined filter configurations. If all criteria are met, the email proceeds to its intended destination. However, if an email fails to meet the necessary conditions, it is either directed to the junk folder or not delivered to the recipient.
During the email’s passage through the spam filtration process, it undergoes assessment and receives a Spam Confidence Level (SCL) score. The higher the SCL score, the greater the likelihood that the email is indeed spam.
Below is the description of the four stages of filtering processed by EOP:
Some of the key features of EOP are listed below:
The protection feature of EOP comes with various small filters that aim at preventing Exchange Online from possible threats.
This feature in EOP allows admins to take action against quarantined emails and submit those mails for analysis.

Exchange Online Protection, a valuable offering from Microsoft, has its share of advantages and drawbacks like any other program. Below are some of the limitations associated with EOP:
Email data breaches are a significant concern associated with EOP, eroding trust among many companies. Third-party tools like Kernel Export Office 365 to PST come to the rescue. This tool efficiently backs up mailbox data from Microsoft 365, Office 365, on-premises Exchange, and hosted Exchange, saving emails in various formats. With this tool, you can safeguard your email server from threats like virus-laden spam emails and malware attacks, making it the ideal choice to secure Office 365 mailboxes.
Exchange Online Protection offers an array of user-friendly features designed to safeguard organizations from spam, viruses, malware, ransomware, and spyware. Accessible through a Microsoft 365 subscription, this program allows for easy customization to meet specific needs. It serves as a crucial shield, ensuring the security of vital data, including emails and attachments.
