CSSCurrent en:Version 7.6.0

Release Date: 02.02.2026

Important Update Notes

Change to the authentication process for Microsoft Exchange Online

This only applies to customers that use Microsoft Exchange Online as a mail server.

All Microsoft Exchange Online customers will have the basic authentication to the mail server getting disabled by Microsoft in the time between March 1st, 2026 and April 30th, 2026, and only will be able to use OAuth authentication. Mandatory changes are required for anyone using Microsoft Exchange Online, as after February 28th, 2026 there will no guarantee that the Cryptshare Server will be able to send emails via the old basic authentication.

Starting with this Cryptshare version, you can now configure the mail server through an OAuth connection to Microsoft Exchange Online.

Here you will find our guide on what to do.

New features

• A new Background Task for the office.js file has been implemented for systems with the Cryptshare for OWA Add-In installed. This task runs daily at 4:00 AM in the background to ensure the file remains up to date. Please ensure that the Cryptshare server is able to communicate to https://appsforoffice.microsoft.com/lib/1/hosted/office.js . If you don't want that the Cryptshare server connects to this Microsoft server, please perform the update of the office.js manually, by downloading it regulary and installing it into the directory resources/products/client.owa and resources/products/client.owaTemplate.
• The transfer status API now allows individual recipients to request status information while ensuring other recipients' data remains private.

Improvements

• The Java runtime environment has been updated to version 25.0.1.
