Microsoft 365 Messaging — Question 41

You have a Microsoft Exchange Online tenant.
You discover that a virus has infected the mailboxes of several users. The users are currently spreading the virus by emailing attachments that contain the virus.
You need to temporarily prevent all users from emailing attachments while you remove the virus from all the mailboxes.
What should you configure?

Answer options

• A. a connection filter
• B. a mail flow rule
• C. a connector
• D. a spam filter

Correct answer: B

Explanation

Configuring a mail flow rule is the correct approach because it allows you to set specific conditions to block attachments in emails temporarily. The other options, such as connection filters and spam filters, do not provide the specific functionality needed to restrict email attachments from all users.
