Product Overview

Email Archive is a service that integrates with Exchange Online and Gmail to store all sent and received emails from inside and outside the company, allowing you to search, view, and download them from the web.

 

Real-time Viewing of Archived Emails

For archived emails within the last year, you can view and download all emails in real-time from the web, including not only the subject and recipient but also the body and attachments.

Unlimited Storage and 10-Year Retention

The archive capacity is unlimited, and archived emails are stored for 10 years.
※ There is a limit to the email capacity that can be archived per day.

Complete Management on the Web

From the Email Archive management screen, you can perform operations such as search, view, and download, and the stored data is kept in the cloud.
Therefore, there is no need for storage or additional purchase of hard disks, leading to reduced management costs.

Legal Evidence Management

In addition to managing internal compliance and internal audits, it can also be used for legal evidence management through email storage.

Retention of Emails for Retirees

Even if you delete the license of groupware (Microsoft 365 / Google Workspace), archived emails are not deleted, so you can still check emails from Email Archive after deleting the license of retirees.
