https://cweb.canon.jp/it-sec/solution/guardian_outbounds/“Outbound Security for Microsoft 365” is an Outlook add-in type service that prevents incorrect transmission of emails. The main cause of erroneous sending of emails is the wrong address or wrong attachment. By introducing "Outbound Security for Microsoft 365", we can expect to strengthen self-checks when sending emails and prevent information leaks due to erroneous sending.
It provides the "Attachment download link" function to be used. With the "attached file download link" function, the attached file will be sent to the recipient in a private state after sending the email. After that, the sender himself/herself accesses the management screen, confirms again that there are no errors in the addressee and the attached file, and makes it public, so that the recipient can download the attached file. This series of operations prevents information leakage from emails. In addition, system administrators can easily introduce “Outbound Security for Microsoft 365” by adopting Microsoft's Outlook add-in function.
From January 2021, "Outbound Security for Microsoft 365" has been providing services limited to free monitors. This time, we will start providing the official version that incorporates the opinions of the monitors and improves the functions. In the official version, it is possible to select the function to use in order to respond to the request to use only one of the "confirmation before sending" function and the "attachment download link" function, which was particularly requested, and the attachment file Improved to be able to select the publication period of when sending. As a result, we will provide Microsoft 365 users with even easier and simple measures against sending emails by mistake.

1. Suppressing erroneous transmissions with "confirmation before sending"
Reduce the risk of erroneous transmissions and information leaks by displaying a pop-up before sending an email and checking the recipient, text, and attached files before sending the email.
2. Sending Attached Files with "Attachment Download Link"
When sending an email, the attached file is automatically uploaded to the server, and the URL for the recipient to obtain the file is automatically inserted into the email text. After sending an email, the sender can set the target file to public after confirming the address and file from the management screen, so it is possible to send the appropriate file to the appropriate destination without sacrificing the convenience of email attachment. I can.
3. Provided as an Outlook add-in
Conventional solutions for countermeasures against misdelivery of e-mails tend to be complicated to set up and operate because they are placed on the e-mail route. The Outlook add-in is directly deployed in the sender's Outlook and does not require any changes to the mail routing. Outlook add-in settings can be centrally set from the Microsoft 365 management screen, so you can easily introduce and start using it.
