Your company has an Exchange Online tenant that contains 2,000 mailboxes.

A partner company named Fabrikam, Inc. uses a third-party messaging solution. The outbound SMTP server for Fabrikam uses an IP address of 131.107.2.22.

You discover that several email messages from the fabrikam.com domain are erroneously marked as spam.

You need to ensure that all the email messages sent from the fabrikam.com domain are delivered successfully to the user mailboxes of your company.

A . Yes
B . No

View Answer

Answer: B

Explanation:

You can allow the server IP address in the Connection Filter. This would achieve the objective of ensuring all email from Fabrikam.com is delivered. However, it would also allow any other company that uses the thirdparty email server to bypass the spam filter.

The fact that the question specifies that Fabrikam uses a “third-party messaging solution” suggests that the answer to this question should be No although technically it would work.
