Microsoft Dynamics 365 Guides End of Life: What Enterprise Customers Need to Know

In October 2025, Microsoft officially announced that Dynamics 365 Guides and Remote Assist will reach end of support on December 31, 2026. This isn't a gradual sunset — it's a hard deadline. After that date: no security updates, no bug fixes, no technical support, no SLA.

For enterprise customers who invested in D365 Guides as their mixed-reality work instruction platform, this creates an urgent migration challenge. Here's everything you need to know.

What Exactly Is Happening?

Three things converged to create this situation:

Dynamics 365 Guides and Remote Assist reach end of support on December 31, 2026. New subscriptions and renewals were stopped as of November 1, 2025.
HoloLens 2 production ended in October 2024. No new devices are being manufactured. Existing devices will continue to function, but with no hardware replacement path.
HoloLens 3 was officially cancelled in February 2025. Microsoft has completely exited the AR hardware market. The military IVAS program was handed to Anduril Industries.

Microsoft's only guidance for affected customers: “explore mixed reality solutions on the Microsoft Marketplace” and “certain Remote Assist scenarios may be covered by Teams Mobile spatial annotation.”

What This Means for Your Organization

If You're Running D365 Guides Today

Your guided procedures will continue to work until the end of 2026. After that, your software is unsupported — meaning vulnerabilities won't be patched, compatibility issues won't be resolved, and Microsoft support tickets won't be answered.

You need to answer three questions:

Content migration: How many guides have you authored? What format are they in? Can they be exported?
Hardware strategy: What happens to your HoloLens 2 fleet? Do you need replacement devices?
Platform replacement: Which alternative platform provides the capabilities you need at a price you can justify?

If You Were Evaluating D365 Guides

Stop. Microsoft is no longer selling new licenses. Any investment in this platform is now a dead end. Redirect your evaluation to platforms that are actively developed and hardware-agnostic.

What to Look for in a Replacement Platform

The D365 Guides experience exposed several limitations that a modern replacement should address:

Device agnosticism — Never bet on a single hardware vendor again. Your platform should work on Quest 3, HoloLens 2 (for remaining fleet life), DigiLens, iPad, Android tablets, and web browsers.
Web-based authoring — D365 Guides required a desktop PC application for authoring. Modern platforms should let you create and edit guides entirely in a web browser.
AI-powered content creation — Manually building every step is slow. AI should help draft guide structures from descriptions and suggest content improvements.
Transparent pricing — D365 Guides was bundled into a $105/user/month D365 Field Service license. Look for platforms with clear, published pricing starting well below enterprise minimums.
Data portability — Your content is yours. Ensure any new platform offers full content export. No lock-in.

Migration Timeline: A Realistic Plan

You have approximately 8 monthsfrom publication of this article. Here's a practical migration timeline:

Month 1 (May 2026): Inventory your current D365 Guides content. Count guides, steps, and media assets. Identify the 10 most critical procedures.
Month 2 (June 2026): Evaluate 2-3 replacement platforms. Run a 30-day pilot with your top 10 procedures on each. Measure authoring time, technician adoption, and feature parity.
Month 3-4 (Jul-Aug 2026): Select your platform and begin migrating the full library. Start with high-frequency, safety-critical procedures first.
Month 5-6 (Sep-Oct 2026): Deploy replacement hardware if needed (Quest 3 is $499 vs. HoloLens 2 at $3,500). Train authors and operators on the new platform.
Month 7-8 (Nov-Dec 2026): Complete migration. Verify all procedures are functional. Decommission D365 Guides instances.

Why GPYB Was Built for This Moment

GPYB (Guided Procedures for Your Business) was designed specifically to fill the gap Microsoft is leaving. Every capability D365 Guides offered — step-by-step spatial instructions, 3D content anchoring, analytics — is available in GPYB, plus capabilities Microsoft never shipped:

Web browser delivery — no app install required on any device
AI-powered authoring — describe a procedure, AI drafts the guide structure
3D spatial editor in the browser — no desktop app needed
Training simulations with scoring — scored, gesture-tracked training
Branching / conditional logic— handle “it depends” scenarios
Remote assist video calling — integrated expert support
Transparent pricing from $399/month — no six-figure contracts

The best time to start migrating from D365 Guides was when Microsoft made the announcement. The second best time is today.
