How can Mimecast assist with email retention policies?

Mimecast can assist with email retention policies by configuring customized retention settings. This allows organizations to establish rules and guidelines tailored to their specific needs for retaining emails for different durations, depending on regulatory requirements or internal policies. Customization is essential because organizations may have varying requirements based on the type of email content, sender, recipient, or other criteria.

By utilizing these customized settings, businesses can ensure compliance with legal and regulatory obligations while also managing their email storage efficiently. This approach enhances data management and minimizes the risks associated with data loss or non-compliance.

In contrast, the other options do not align with the purpose of email retention policies. Automatic deletion of all emails would contradict the objective of retaining important correspondence. Unlimited storage does not address the need for structured retention policies. Blocking access to archived emails would prevent users from retrieving important records, which undermines the concept of effective data management.
