Microsoft recently announced that it will begin blocking Exchange Web Services (EWS) requests in Exchange Online starting October 1, 2026. As the platform transitions to the more secure and modern Microsoft Graph API, you might be wondering how this major update impacts your IT environment.

This blog post breaks down exactly what the EWS deprecation means for your organization and how IssTech is working closely with our trusted partner, AvePoint, to manage the transition seamlessly. We are proactively tracking updates, validating your managed services and backups, and ensuring all necessary data flows shift to the Graph API well before Microsoft's deadline.

Currently, no immediate action is required on your part. We are handling the heavy lifting so you don't have to! If you need to approve new Microsoft Graph permissions in your tenant down the line, IssTech will provide plenty of advance notice and clear, step-by-step guidance. Read the full post to learn more about our proactive approach, and find out how to stay informed on all critical IT updates.

• The "Rebuild It" Myth: Relying solely on automated pipeline rebuilds instead of dedicated backups is a failing strategy in modern cloud and Kubernetes environments.

• Why Pipelines Fail: Code redeployment cannot restore lost persistent data, replace undocumented tribal knowledge, or function during major repository outages.

• Unpredictable New Threats: Unforeseen risks—such as autonomous AI agents creating hidden dependencies or sudden geopolitical shifts—require true disaster recovery, not just quick automated fixes.

• The Wisdom of Regulation: Compliance frameworks like DORA and NIS2 shouldn't be viewed as bureaucratic hurdles, but as hard-learned lessons from past IT disasters codified to protect your business.

• The Bottom Line: IssTech emphasizes that an independent, robust data protection strategy is the only reliable safety net against the industry's ever-evolving "unknown unknowns."
