Why Archive Emails?

Emails are not only an important means of communication, they’re also a comprehensive and valuable information resource for any company. Besides business correspondence, they can contain quotes, contracts, invoices and sales data, and even classified company information, such as data on internal work processes or financial data. Managing this information resource efficiently is an elementary component of any successful corporate strategy and one of the prime tasks of information management. This is where email archiving can provide valuable support in helping a company make the best use of the business-critical data contained in emails. Read our free Guide to Email Archiving to learn more.

Compliance features of MailStore Server

The comprehensive technology concept of MailStore Server helps companies to meet a growing number of compliance requirements and can also assist with eDiscovery scenarios.

Help with fulfilling GDPR obligations

MailStore Server is regularly certified by independent data privacy experts according to the EU’s General Data Protection Regulation (GDPR). The software can help you meet obligations under the GDPR, among others, by defining sophisticated retention policies. You can request a copy of the official GDPR audit certificate from [email protected].

Comprehensive technology concept
  • Completeness through journaling
    MailStore Server enables the complete archiving of all emails in the company. For example, emails can be archived before they are even delivered to employees’ mailboxes.
  • Authentic archiving
    Archived emails match the original in every respect and, when required, can be restored from the archive without any loss of information.
  • Tamper-proof storage
    Thanks to the formation of SHA hash values on the content of emails and the use of internal AES256 encryption, MailStore Server helps to protect archived data from manipulation.
  • Tamper-proof export
    Emails can be exported from the archive if required and made available to others in standard file formats. Exported emails match the original in every respect. A cryptographic signature can be added to exported emails in order to protect them against tampering while they are outside the archive.
  • Retention policies
    By creating individual retention policies, administrators can retain full control over how long different types of emails are archived. For example, they can decide whether and, if so, when emails should be automatically deleted from the archive, thus complying with different statutory retention periods. Policies like these can also help a business comply with the EU’s General Data Protection Regulation (GDPR).
  • Legal hold
    While legal hold is activated, no emails can be deleted from the archive – irrespective of how other user rights or retention policies, etc. have been configured.
  • Logging
    Thanks to an integrated auditing function, MailStore Server can log specific changes and events as defined by the administrator.
  • Auditor access
    External auditors can be granted access to the archive via a special “Auditor” user type.

MailStore Server creates perfect copies of all emails in a central archive, thus ensuring the availability and security of any amount of data, even over many years.

With the help of retention policies, they can even define the criteria under which certain emails are automatically deleted from the archive. The archive can deal with even very large volumes of data effectively, providing all a company’s users with fast and convenient access to archived emails and their attachments.
