Use Meeting Insights in New Outlook After Switching From Classic Outlook

When you switch from Classic Outlook to the new Outlook for Windows, you might notice that meeting-related information from your emails no longer appears automatically in your calendar. This feature, called Meeting Insights, helps you prepare for meetings by showing relevant emails, documents, and tasks without manual searching. The new Outlook handles this feature differently because it uses a cloud-based architecture instead of a local data file. This article explains how to enable and use Meeting Insights in the new Outlook after migrating from Classic Outlook.

Why Meeting Insights Behave Differently in New Outlook

Classic Outlook stores all your data in a local PST or OST file. When you opened a meeting, Outlook scanned your local mailbox for related emails and files using search folders and add-ins. This process ran entirely on your computer and did not depend on a server.

The new Outlook for Windows is a cloud-connected app. It does not use local PST or OST files. Instead, it syncs your data from Exchange Online through Microsoft 365. Meeting Insights in the new Outlook rely on the Microsoft Graph API, which analyzes relationships between calendar items, emails, and files stored in your cloud mailbox. This means the feature only works if your account is connected to Exchange Online.

When you switch from Classic Outlook, the new Outlook does not automatically migrate your local search folders or add-in configurations. You must turn on Meeting Insights manually in the settings. The feature also requires that your mailbox index is up to date on the server. If you recently migrated your data to the cloud, it can take up to 24 hours for the server to fully index your content and start showing insights.

Steps to Enable and Use Meeting Insights in New Outlook

Before you begin, confirm that you are using a Microsoft 365 work or school account. Meeting Insights are not available for personal Outlook.com accounts or for accounts using POP or IMAP. You also need an active internet connection because the insights are generated on the server.

1. Open Calendar settings
   In the new Outlook, go to the top menu and select View > View settings. In the Settings pane, click Calendar on the left side. Then click Events and invitations.
2. Enable Meeting Insights
   Under the Events and invitations section, locate the option labeled Meeting insights. Turn the toggle to On. The setting may also be named Show suggestions for meeting preparation depending on your update channel. Close the Settings pane to save the change.
3. Open a calendar event
   Go to your calendar and double-click any existing meeting or appointment. The event details window opens. Look for the Insights tab or a small lightbulb icon near the top of the event window. If you do not see it, click the More options button (three dots) and select Show insights.
4. Review the suggested content
   The Insights panel lists emails, documents, and tasks related to the meeting. Click any item to open it directly in the reading pane or in a separate window. The list updates automatically as new emails arrive or as files are modified.
5. Search for additional items manually
   If the Insights panel does not show everything you need, use the Search box at the top of the event window. Type a keyword or a person’s name. The search results include emails and files from your entire mailbox, not just the automatically related items.

What to Do If Meeting Insights Are Still Missing

If you turned on the setting but still see no insights, check the following:

1. Verify your account type
   Go to File > Account > Account settings. Your account should show Microsoft Exchange as the server type. If it shows POP or IMAP, Meeting Insights will not work. You must add your Microsoft 365 account again using the Exchange protocol.
2. Wait for server indexing
   After enabling the setting, close and reopen Outlook. If you recently added your mailbox to the new Outlook, allow up to 24 hours for the server to build the relationship index. During this time, insights may appear gradually.
3. Check the event type
   Meeting Insights only appear for meetings that you created or that you accepted. Private appointments that you set up on your own calendar do not generate insights unless they include attendees.

If Meeting Insights Still Have Issues After the Main Steps

Insights show outdated or irrelevant content

The insights algorithm prioritizes emails and files from the last 30 days. If you have many older emails in the same conversation thread, the system may pick up stale items. To refresh the insights, close the event and reopen it. You can also manually search for the correct email and pin it to the top of the Insights panel by clicking the pin icon next to the item.

Insights panel is missing entirely

Some organizations disable Meeting Insights through group policies. If the toggle in Calendar settings is grayed out or missing, contact your Microsoft 365 administrator. They can enable the feature in the Exchange admin center under Organization > Insights. The admin must set the MeetingInsightsEnabled parameter to $true for your tenant.

Insights work in Classic Outlook but not in new Outlook

Classic Outlook uses local add-ins and search folders that do not transfer to the new app. You cannot migrate those customizations. The new Outlook relies entirely on server-side intelligence. If you need a specific email to appear for every recurring meeting, add that email as a note inside the meeting body or attach it directly to the event. The server will then link the attachment to the meeting.

Classic Outlook vs New Outlook Meeting Features

Item	Classic Outlook	New Outlook
Data storage	Local PST or OST file	Cloud mailbox on Exchange Online
Insight source	Local search folders and add-ins	Microsoft Graph API server analysis
Setup required	Add-ins installed manually or via policy	Toggle in Calendar > Events and invitations
Account types supported	Exchange, POP, IMAP, Outlook.com	Exchange Online only
Update frequency	Real-time based on local index	Up to 24 hours after mailbox migration
Customization	Create custom search folders	Pin items manually in the Insights panel

After you enable Meeting Insights in the new Outlook, you can prepare for meetings without leaving your calendar. The feature saves time by pulling together related emails and files automatically. For recurring meetings that require the same reference material every time, attach those files directly to the meeting invitation so they appear in the Insights panel consistently.
