Important Update Notes

Change to the authentication process for Microsoft Exchange Online.

Effective February 28, 2026, Microsoft will change the authentication process from basic auth to oauth.

Mandatory changes are required for anyone using Microsoft Exchange Online, as after this date it will no longer be possible to send emails via basic auth.

This only applies to users of 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.

Bug Fixes

• Resolved an issue that caused backups from not being restored correctly.
