MailStore V13: Soporte mejorado de servicios en la nube y autentificación moderna

With several new features and numerous improvements, our new version will not only please admins but end users and business owners too. “We’ve divided these features into four main categories,” explains Björn Meyn, Product Manager at MailStore. “Firstly, we’ve improved our software’s interaction with the key cloud-based services Microsoft 365 and Google G Suite, ensuring much easier integration with these services. MailStore 13’s second focal point is supporting modern authentication through OAuth2 and OpenID ConnectIncreased security and an improved user experience are our third and fourth main categories. Long-standing MailStore customers will know that we take both these topics very seriously and that they play a major role in absolutely every release.”

What Admins Can Expect From V13

MailStore 13 offers several new features and improvements that simplify the work of administrators. Here are some of the features that are particularly relevant for admins:

Improved Support of Cloud-Based Services and Modern Authentication

MailStore Server and the MailStore Service Provider Edition (SPE) now support OAuth2 and OpenID Connect, which significantly enhances MailStore’s integration in the cloud-based environments of Microsoft 365 and Google G Suite. This is good news for admins, as it not only enhances MailStore’s user friendliness in combination with these cloud-based services, but also increases security. Administrators benefit from standardized login policies by being able to use the same settings of their Microsoft 365 or Google G Suite clients for MailStore Server (including e.g. multi-factor authentication) without having to enable legacy authentication or the less secure application access. The new two-step login process emulates the login routines used in modern web applications, and MailStore no longer has to process the passwords of remote users during authentication.

In addition, the new dedicated Microsoft 365 archiving and export profiles make it easier for admins to configure profiles. Here too, the support of modern OAuth2 authentication not only improves security but also integration with Microsoft 365.

MailStore Version 13 offers improved integration with Microsoft 365 – for example through a new user synchronization to support modern authentication.

The dedicated archiving profiles for Microsoft 365 make the work easier for the IT admin.

Network Share Management

MailStore Server admins now benefit from improved management of network share settings. These settings can now be managed more comfortably and securely via MailStore Server’s Service Configuration rather than via the startup script – e.g. when using a NAS.

Group Policies

Creating group policies for the MailStore Client and the MailStore Outlook Add-in is now easier than ever before: in the case of MailStore Server, the templates are now included in the installation, while in the SPE, they can be downloaded from the Client Access Server’s default page. In Version 13, these templates are available in all languages supported by MailStore.

Certificate Validation

A further improvement for MailStore Server and SPE administrators is the new certificate validation. This has been aligned with the validation process used in most of the important web browsers, enabling administrators to create and implement standardized security and certificate policies for all MailStore clients (MailStore Client, Outlook-Add-in and Web Access).

Encrypted Connections Only

In Version 13, the support of unencrypted connections to MailStore Server has been completely removed. So, administrators can rest assured that all MailStore Server installations permit only encrypted connections with the archive, which can be particularly useful for administrators managing several installations.

Let’s Encrypt™-Certificates

Administrators can now specify a port on which MailStore Server should listen out for the validation requirements of Let’s Encrypt™ TLS-Certificates, thus avoiding port collisions e.g. when MailStore Server is being run with other services on a computer or where only a limited number of IP addresses is available. This simplifies the use of Let’s Encrypt certificates.

MailStore Gateway

In Version 13, administrators can immediately see how many messages are in a MailStore Gateway mailbox. The new version also allows mailboxes still containing messages to be forcibly deleted. Furthermore, the Management Web Interface port can be modified if the standard port is being used by different applications, or the administrator wishes to turn it into a standard HTTPS Port 443.

How End Users Stand to Benefit From the New Version

MailStore 13 also offers several new and improved features aimed at simplifying archive handling for the end user. These include:

Modern Authentication

MailStore Server and SPE users can now login to MailStore using their customary Microsoft 365 or Google G Suite login details. So, rather than having to remember separate passwords for MailStore, all they need to do is use their Microsoft 365 or Google G Suite login data. This way they can also benefit from the additional security features of these cloud-based services when accessing their archive, such as multi-factor authentication.

Removal of Mobile Web Access

Customers who previously used Mobile Web Access for MailStore Server and the SPE are now able to use our modern and secure responsive Web Access. The legacy Mobile Web Access is no longer available in Version 13.

Client-Based Improvements

MailStore Server and SPE users benefit from a number of improvements when it comes to accessing and using the archive. The loading time of the responsive Web Access, in particular, has been significantly reduced. Various other minor improvements as well as comprehensive updating of all web components have been carried out for an even smoother search experience, particularly on mobile devices. The responsive display on mobile devices has also been improved significantly and features, among other things, a larger reading area. Meanwhile, the new “jump to folder” function allows you to switch directly to a desired folder by clicking on the folder path in the message view, which makes it even easier to find emails belonging to the same project or public folder. Time information is also displayed alongside the date in the MailStore Client’s message list.

Clicking on the folder path takes you to the respective folder.

Encrypted Connections Only

In Version 13, unencrypted connections to MailStore Server are no longer supported. This means that end users receive fewer warning messages when using a modern web browser to access the archive, while being able to rely on secure connections with MailStore Server. It’s also easier for end users to verify the security of a connection via their browser (e.g. via the lock symbol in Chrome’s address bar). This is particularly useful when using non-trusted connections, such as public wireless networks at airports.

Certificate Validation

In both MailStore Server and the SPE, this has been aligned with the certificate validation routine of the most important web browsers, enabling end users to identify breaches of security policies across all clients (MailStore Client, Outlook Add-in and Web Access).

Why Business Owners Can Look Forward to V13

It goes without saying that management also stands to benefit when email handling is simplified for administrators and end users. However, there are three more arguments in favor of MailStore 13 that are particularly relevant for business owners:

Improved Support of Cloud-Based Services and Modern Authentication

Business owners can trust in their investment in MailStore in the long-term, as a key part of our philosophy is to permanently support current industry standards and technologies – and that goes for important cloud-based services such as Microsoft 365 and Google G Suite.

Encrypted Connections and Standardized Certificate Validation

Business owners can also rest assured that MailStore will continually upgrade the security concept of its software in line with industry standards and security recommendations. That said, we always keep in mind the requirements and the IT infrastructure of small and medium-sized businesses. Our motto is “Security by Default”. This makes MailStore a reliable long-term choice when it comes to email archiving solutions.


Just like the previous version, MailStore Server 13 has been rigorously audited by an independent data protection expert under General Data Protection Regulation (GDPR) rules. This certification verifies that MailStore Server – when used appropriately – meets the personal data processing requirements set out in the GDPR. Thanks to these regular and independent software audits, business owners can rest assured that MailStore Server can help them meet their obligations under the GDPR, for example by defining sophisticated retention policies.

And What About MailStore Home Users?

While the focus of Version 13 undeniably lies with our commercial products MailStore Server and the MailStore SPE, home users of our free archiving solution MailStore Home are not left empty-handed. In Version 13, MailStore Home also includes the practical “jump to folder” function, which allows emails from the same folder to be easily located by clicking on the folder path. End users can also be more creative with their passwords, which can now include spaces at the beginning and end. Other minor improvements and fixes result in an improved user experience for end users with MailStore Home.
