New Features for MailStore Server and the MailStore Service Provider Edition

Find out more about the improvements you can expect in Version 22.3 of MailStore Server and the MailStore SPE.

Support for Microsoft Outlook 2021

Our email archiving solutions have a reputation for supporting the latest mail servers and clients. Following this tradition, MailStore 22.3 now officially supports Microsoft Outlook 2021, which means you can use your MailStore Outlook Add-in with Microsoft’s latest email client. This gives you maximum flexibility and autonomy when it comes to choosing an email client. Email archiving is a long-term solution that aims to safely retain your emails and attachments over many years. So, it’s important for us to know that your long-term investment in MailStore is protected and that our software will remain compatible with all your systems in the future.

More Security

Long-time MailStore customers and partners know that every new version of our product comes with added security. And it’s no different this time. The new version prevents brute-force attacks during the login routine. Failed login attempts, i.e. using incorrect credentials, causes the login process to slow down: fraudsters are unable to deploy brute-force methods and your email archive remains protected.

Even Better Usability

In addition, MailStore 22.3 enhances the experience for MSPs using the MailStore SPE. Admins are now able to modify the automatic execution of profiles on the server via the API. MSPs can adapt and save on system resources. We’ve also improved the login routine of the MailStore Outlook Add-in.

Updated Certification: Meeting Data Privacy Requirements

The certification takes into account all relevant aspects of the European General Data Protection Regulation (GDPR) and affirms that, when used appropriately, both MailStore Server and the MailStore SPE meet all the requirements governing the processing of personal data set out in the GDPR.
