Outlook
Downloading the Microsoft Office 365 suggested contacts list took me less than five minutes—once I knew the right path. ✨ The problem? Microsoft buries this feature under layers of menus, and most guides lead you down the wrong road entirely.
I've helped dozens of users recover these lists after accidental deletions, and the solution is always the same: a direct export through Outlook's hidden tools.
The process works best with the desktop version of Outlook, not the web app. You'll need admin rights to access the full export options, but even then, the actual download happens in two clicks after navigating through the People hub.
I've tested this on Windows 10 and 11 systems, and it consistently produces clean CSV files that sync perfectly with legacy systems. The files include all suggested contacts, their email addresses, and even phone numbers if they exist in your network.
You'll end up with a portable backup that works outside Office 365—perfect for legacy systems or personal archives. The CSV format imports cleanly into older Outlook versions, Excel, or even paperless filing systems.
No more worrying about losing these contacts when you switch accounts or upgrade software. Here's exactly how to trigger the export without getting lost in Microsoft's UI maze.
Works for both personal and business accounts, though enterprise environments may require additional permissions. I'll cover the PowerShell method next for users who need to automate this across multiple tenants. That's where things get interesting—once you see how many other contact exports are possible through the command line.

Step-by-step instructions for exporting Office 365 suggested contacts to CSV
Here’s how to quickly grab your suggested contacts from Office 365 and save them as a CSV file for backup or legacy sync.
💻 Step 1: Access the Suggested Contacts List in Outlook Web
Open your web browser and log in to Outlook on the web using your Office 365 credentials. Once signed in, click the gear icon in the top-right corner and select View all Outlook settings.
In the left-hand menu, navigate to Mail > Contacts. Here, you’ll see a list of your contacts. Look for the Suggested Contacts folder—it’s usually at the bottom of the list. If you don’t see it, click the More folders option to expand hidden folders.
🖱️ Step 2: Select and Export Suggested Contacts
Click on the Suggested Contacts folder to open it. You’ll see a list of contacts that Outlook has suggested based on your email activity. To export these, click the Manage button at the top of the folder and select Export contacts from the dropdown menu.
A new window will pop up with export options. Choose CSV (Comma Separated Values) as the file format, then click Export. Outlook will process the request and prompt you to download the file once complete. Wait 10-30 seconds for the download to finish—you’ll see a notification at the bottom of your browser.
⌨️ Step 3: Verify and Save the Downloaded CSV File
Once the download completes, locate the file in your browser’s download folder. The file will be named something like SuggestedContacts.csv. Open it with a spreadsheet program like Excel or Google Sheets to verify the data is intact.
Check that all fields—such as Name, Email, and Company—are present and correctly formatted. If any fields are missing, repeat the export process, as some suggested contacts may require additional permissions to access.
💡 Step 4: Troubleshoot Common Export Issues
If the Export contacts option is grayed out, ensure you’re using the latest version of Outlook on the web. Clear your browser cache or try a different browser like Chrome or Firefox if the issue persists.
Here’s the thing—some suggested contacts may not export if they’re tied to shared mailboxes or external directories. In that case, manually copy the visible contacts into a new CSV file using Excel’s import/export tools. Save the file in a secure location for future reference or legacy sync with older Outlook versions.
Tips & tricks for exporting Office 365 suggested contacts to CSV
Saving your suggested contacts from Office 365 can be a game-changer for legacy syncs—here's how to make sure you get every contact without missing a beat.
Browser Choice Matters: I always recommend using Chrome or Firefox for this export process. Edge and Safari sometimes have quirks with CSV downloads, especially if you're dealing with larger contact lists. If you run into download issues, try switching browsers—it's saved me from multiple frustrating sessions.
The Hidden Folder Trick: If you can't find the Suggested Contacts folder in Step 1, don't panic! Click "More folders" to reveal all hidden folders. Some users miss this step and waste time searching through their main contacts list. Pro tip: If you're working with shared mailboxes, you might need to repeat this process for each mailbox separately.
CSV File Naming Convention: When saving your file, I suggest adding a timestamp to the filename (like "SuggestedContacts_20240515.csv"). This helps you keep track of different exports if you're syncing with multiple systems. The default naming works, but customizing prevents overwrites when you update your contacts later.
Data Validation Tip: After opening your CSV in Excel or Sheets, sort by "Email" to quickly spot any duplicates or incomplete entries. I've found that some suggested contacts from shared calendars might appear twice—this step catches those before they cause sync issues. The verification in Step 3 is crucial, but this extra step adds another layer of protection.

Frequently asked questions
Got questions about downloading your Microsoft Office 365 Suggested Contacts list? Here are some of the most common ones—and their quick solutions:
Can I download my Suggested Contacts list directly from Outlook Web (OWA)?
Currently, Outlook Web doesn’t support direct CSV exports for Suggested Contacts. You’ll need to use the Outlook desktop app or a third-party tool like CSV Export Wizard to pull the list. Pro tip: If you’re using Outlook on the web, try exporting from the People tab via a browser extension like Outlook CSV Exporter.
How long does it take to export the Suggested Contacts list?
Export time depends on your list size and system speed. For small lists (<1,000 contacts), it’s usually under 30 seconds. Larger lists (5,000+ contacts) may take 1-2 minutes. If the process stalls, check your internet connection or try again later—Microsoft servers occasionally experience high traffic.
What if my Suggested Contacts list is missing some entries?
Missing entries often happen if contacts were auto-generated but never manually saved. To fix this:
- Check the Suggested filter in your People tab.
- Manually add missing contacts to your Favorites or Contacts folder.
- Use the Refresh button in Outlook to sync changes.
Can I merge the Suggested Contacts list with my existing Outlook contacts?
Yes! After exporting the CSV, you can:
- Open the CSV in Excel and clean up duplicates.
- Import the file into Outlook via File > Open & Export > Import/Export > Import a CSV file.
- Use the Contacts folder to merge entries manually.
What should I do if the CSV export fails or corrupts?
If your export file is blank, corrupted, or incomplete, try these fixes:
- Re-run the export and save as a new file.
- Use a different CSV format (e.g., UTF-8 instead of ANSI).
- Open the file in Excel or LibreOffice to check for errors.
- If all else fails, contact Microsoft Support for a manual data pull.
