Copilot in Outlook: Meeting Preparation Is About to Get Smarter

Currently, the “Prepare for meetings with Copilot” feature requires at least three participants. Starting mid-October, this is changing. Copilot will soon support all meetings, including 1:1s. The rollout will begin in mid-October and is expected to complete by November 2025 according to the message center. With this update, you’ll also see new real-time insights in the Outlook meeting event form, summarizing relevant context, tasks, documents, and other resources. Plus, you’ll be able to chat with Copilot to confirm action items or better understand meeting goals. The more context Copilot has, the better it works. Meeting series with related emails, shared documents, Teams chats, and previous Copilot transcriptions deliver the richest experience. If your organization limits Copilot to in-meeting use only and deletes content afterward, you’ll miss out on much of this value. Here is a relevant " how to " guide for users.

EWS in Exchange online is about to be retired

In 2018, Microsoft announced the discontinuation of feature updates to Exchange Web Services (EWS) in Exchange Online, urging developers to transition to Microsoft Graph. Now, Microsoft has announced that starting October 1, 2026, EWS requests from non-Microsoft applications to Exchange Online will be blocked.

This is a significant change that emphasizes the need for IT departments to take action. It's crucial to start mapping existing tools, scripts, or integrations that rely on EWS and plan for their transition.

There's no direct way to opt out of this change. The change only applies to Microsoft 365 and Exchange Online. EWS in Exchange Server will not be affected.
