Recommended environment for browsing mail
From the second half of 2019, our email system will be transferred from the on-premises email system to the G Suite cloud email system. This has several advantages.
- Because of the system on the cloud, the downtime due to trouble is expected to be considerably shorter than on-premise systems.
- G Suite's high-performance filtering system can be used for virus mail and spam mail filtering.
- Searching mailboxes is very fast.
On the other hand, there are the following disadvantages.
- Because it is a very general mail system on the cloud, it is easy to encounter phishing damage. To solve this problem, multi-factor authentication using a staff ID card or smartphone is required.
- GSuite's cloud mail system is quite different from the conventional mail system. In particular, mailboxes change to the concept of labels in GSuite. Therefore, it is necessary to review how to us．
For these reasons, it is recommended that the Information Media Infrastructure Center use a web browser or a dedicated application as an environment for browsing emails.
