When you type in the search bar of the new Outlook for Windows, you see a list of suggested emails, contacts, and files before you press Enter. This feature is called Search Mail Suggestions. It replaces the older search behavior where you had to click a separate search tab or use advanced query syntax to find results. The suggestions appear as you type, showing the most likely matches based on your recent activity and frequent contacts. This article explains how Search Mail Suggestions work, how to use them effectively, and what differences exist compared to classic Outlook search tools.
Key Takeaways: Using Search Mail Suggestions in New Outlook
- Search bar at top of window: Type a name, subject, or keyword to see suggestions appear in a dropdown list below the search bar.
- Click a suggestion or press Enter: Click any suggestion to open that email or contact directly; press Enter to run a full search for all matching items.
- File > Options > Search > Search Suggestions: Turn Search Mail Suggestions on or off if you prefer the classic search results list.
How Search Mail Suggestions Work in New Outlook
Search Mail Suggestions are a search-as-you-type feature built into the new Outlook for Windows. When you click the search bar at the top of the Outlook window and start typing, Outlook immediately queries your mailbox index and displays a dropdown list of the most relevant results. The suggestions include:
- Emails – recent messages whose subject, sender name, or body contains your search term.
- Contacts – people in your address book whose name matches what you typed.
- Files – attachments or cloud-stored documents linked to messages in your mailbox.
- Calendar events – upcoming or past appointments that include your search term.
The suggestions are ranked by relevance. Outlook considers how recently you interacted with a message or person, how frequently you email them, and whether the item is in your focused inbox. This ranking means the first few suggestions are almost always the items you want.
Search Mail Suggestions require an active internet connection for the new Outlook. The feature uses Microsoft 365 cloud search to generate suggestions, not just the local Windows Search index. This approach gives faster and more accurate results for users with large mailboxes.
Prerequisites for Using Search Mail Suggestions
You must be running the new Outlook for Windows, which is available to Microsoft 365 subscribers and users with a Microsoft 365 work or school account. Classic Outlook (Outlook 2019, 2021, or older) does not have this feature. Your mailbox must be hosted on Exchange Online or Microsoft 365. On-premises Exchange mailboxes do not support Search Mail Suggestions in the new Outlook.
How to Use Search Mail Suggestions Effectively
- Click the search bar
Click inside the search bar at the top of the Outlook window. The default placeholder text reads “Search.” A blinking cursor appears. - Type a search term
Type a name, subject keyword, or phrase. For example, type “Q4 report” or “Jane Smith.” Do not press Enter yet. - Review the suggestions dropdown
After typing two or three characters, a dropdown list appears below the search bar. The list shows up to 10 suggestions, grouped by type: emails, contacts, files, and calendar events. - Click a suggestion to open it
Click any email suggestion to open that message in the reading pane. Click a contact suggestion to open that person’s contact card. Click a file suggestion to download or open the attachment. - Press Enter to run a full search
If the suggestion you need does not appear, press Enter. Outlook runs a full search and displays a complete results list in the main window. This list includes all matching items, not just the top 10. - Refine your search from the results list
After pressing Enter, use the search tools at the top of the results list to filter by folder, date range, or sender. Click the filter button to narrow results further.
Turning Search Mail Suggestions On or Off
- Open Outlook Options
Click File in the top-left corner, then click Options in the left navigation pane. - Go to Search settings
In the Options dialog, click Search in the left sidebar. - Toggle Search Suggestions
Under Search Suggestions, clear the check box labeled “Show search suggestions as I type.” Click OK to save the change. When this option is off, typing in the search bar shows no dropdown, and you must press Enter to see results.
Common Mistakes and Limitations to Avoid
Search Mail Suggestions Do Not Appear
If no suggestions appear when you type, check that the new Outlook is fully signed in to your Microsoft 365 account. Open File > Account Settings to verify your connection. Also confirm that the search suggestions option is enabled in File > Options > Search. If you are using an on-premises Exchange mailbox, suggestions will not work.
Suggestions Show Old or Irrelevant Results
The suggestions are based on your recent activity and the mailbox index. If you have not opened or sent emails to a contact recently, that contact may not appear in suggestions. To find an older contact, type their full name and press Enter to run a full search. You can also use the People icon in the navigation pane to browse all contacts.
Cannot Find Attachments via Suggestions
File suggestions only show attachments from messages in your mailbox. Files stored in OneDrive or SharePoint that were not sent as attachments do not appear in Search Mail Suggestions. To find those files, use the OneDrive search or the SharePoint document library instead.
Search Suggestions Interfere with Keyboard Navigation
Some users find that the dropdown suggestions block the first few results when they press Enter. To avoid this, press the Escape key to dismiss the suggestions dropdown before pressing Enter. Alternatively, use the down arrow key to highlight a suggestion and press Enter to open that specific item.
Search Mail Suggestions vs Classic Outlook Search: Key Differences
| Item | Search Mail Suggestions (New Outlook) | Classic Search Tools (Outlook 2019/2021) |
|---|---|---|
| Search trigger | Suggestions appear as you type without pressing Enter | No suggestions; must press Enter to see results |
| Result types shown | Emails, contacts, files, calendar events mixed in one dropdown | Only emails unless you use separate search tabs for People or Files |
| Search index used | Microsoft 365 cloud search index | Local Windows Search index on your computer |
| Offline capability | Requires internet connection; no offline suggestions | Works fully offline using cached data |
| Filtering options | Filters appear after pressing Enter in the results list | Search tab ribbon with inline filters before searching |
| Keyboard shortcut | Ctrl+E or click search bar | Ctrl+E or F3 to open search |
Search Mail Suggestions give you faster access to the most relevant items without typing the full search query. You can now find recent emails, contacts, and attachments in one or two keystrokes. If you prefer the classic behavior where search only shows results after pressing Enter, turn off suggestions in File > Options > Search. For power users, combining Search Mail Suggestions with the Ctrl+E keyboard shortcut and the Escape key to dismiss suggestions offers the fastest navigation workflow.
