Time & Attendance: Browser Changes Affecting Microsoft Remote Desktop Web Access (RD Web)

Aim

This article is about upcoming browser changes affecting Microsoft Remote Desktop Web Access (RD Web) and provide guidance on mitigation options.

Objectives
  • Understand the impact of browser changes on RD Web access.
  • Identify if your organisation is affected.
  • Review available mitigation options.
  • Plan for the long-term solution.
Understanding the Browser Changes

The warning messages seen in the application are due to Google Chrome and Microsoft Edge removing support for browser-based XSLT technology used by traditional RD Web environments.

What Will Users See?

Affected users may see a banner notification. This banner is informational and does not indicate an immediate service outage. Its purpose is to:

  • Raise awareness of the upcoming browser changes.
  • Help organisations identify users accessing applications through RD Web.
  • Encourage customers to review the available mitigation options.
  • Provide visibility while a longer-term solution is developed.
Who Is Affected?

This notice applies to customers who:

  • Access applications through Microsoft RD Web.
  • Use Google Chrome or Microsoft Edge.
  • Launch published applications through a browser-based RD Web portal.

Note: Customers using the Payroll or Time & Attendance web application are not impacted.

Available Mitigations

There are two methods available to continue using RD Web while long-term solutions are assessed.

Option 1: Install an XSLT Browser Extension

  1. Install an XSLT browser extension to restore browser support for XSLT functionality.
  2. Evaluate any browser extensions in accordance with your organisation's security and governance policies.

Option 2: Enable XSLT Through Browser Group Policy

  1. Enable XSLT through browser enterprise controls provided by Chrome and Edge.
  2. Consult your internal IT teams regarding deployment of browser enterprise policies.
Important Dates
  • November 2026: Browser vendors begin removing XSLT functionality from mainstream browser releases.
  • August 2027: Temporary enterprise mitigation options are scheduled to be removed. XSLT support will be fully retired.
Our Long-Term Plan

We are:

  • Assessing alternative access methods.
  • Evaluating solutions that remove the dependency on browser-based XSLT.
  • Testing replacement approaches with our platform teams.
  • Monitoring guidance from Microsoft and Google regarding future browser support.
Frequently Asked Questions

Does this mean RD Web has stopped working?

No, the banner is an early warning notification.

Do I need to take action immediately?

Not necessarily, but organisations using RD Web should review the mitigation options and begin planning ahead.

Which mitigation should I use?

Discuss both options with your IT team to determine the most appropriate approach.

Is a permanent fix available?

Not yet, we are actively working on a long-term solution.

Conclusion

The upcoming browser changes will affect RD Web access for some customers. Review the mitigation options and plan accordingly. Further updates will be shared as our remediation strategy is confirmed.
