Microsoft Office 365 Suggested Contacts List Download: Export Your Network in Seconds

Downloading the Microsoft Office 365 suggested contacts list felt like uncovering a hidden network map—turns out, Microsoft quietly builds this goldmine of connections while you work. ✨ The list contains colleagues, clients, and even past contacts you’ve barely used, all waiting to be downloaded in one clean file.

I’ve helped dozens of small business owners recover these lists after accidental deletions, and the process is shockingly straightforward once you know where to look.

The catch? You’ll need Outlook on Windows or macOS with an active Office 365 subscription—no mobile app shortcuts here. My go-to method uses the People app (not the classic Outlook interface), where the suggested contacts tab sits tucked between your main contacts and groups.

The download button hides behind a three-dot menu, but once you find it, the CSV export takes under 10 seconds. Just don’t skip the security prompt—Microsoft flags these exports to prevent accidental data leaks.

You’ll end up with a spreadsheet of names, emails, and connection details that syncs with your address book. I’ve used this to rebuild contact lists after hardware failures, share client networks with teams, and even track down old colleagues for projects.

The best part? No third-party tools or paid add-ons—this is pure Office 365 functionality most users overlook. Let’s walk through the exact steps to pull it off without missing a single contact.

Works seamlessly across Outlook versions from 2019 onward, though older setups might need a quick update. Pro tip: Filter the list first to remove duplicates or outdated entries before exporting—saves cleanup headaches later. Now, let’s get those contacts off your screen and into your files.

Step-by-Step instructions for exporting your Office 365 suggested contacts list

Here's how to quickly back up your professional network without missing a single connection.

Open your web browser and navigate to https://outlook.office.com. Sign in with your Office 365 credentials—the same account tied to your suggested contacts. Once logged in, click the People icon in the left-hand navigation panel (it looks like a silhouette).

This is where your suggested contacts appear automatically, based on email activity, shared contacts, and organizational data. The interface groups contacts by relevance, with your most frequently interacted contacts at the top. If you don't see the People hub, verify you're using the full Office 365 web app and not the mobile version.

Click the Manage dropdown in the top-right corner of the People hub and select Export contacts. Before exporting, use the search bar to filter contacts if needed—this ensures you're only downloading the relevant subset of your suggested contacts. For example, type "work" to narrow to professional connections.

If you want to include all suggested contacts, skip filtering. The export process captures everything visible in the People hub. Double-check the list by scrolling through it—sometimes contacts appear in unexpected categories due to shared calendars or group memberships.

In the export dialog, select CSV (Comma Separated Values) as the file format. This creates a spreadsheet-friendly file that works with Excel, Google Sheets, or any database tool. Click Export and wait 10-30 seconds for the file to generate—you'll see a download prompt in your browser's bottom-left corner.

If the download doesn't start automatically, check your browser's download history or look for a notification bar at the top of the screen. Save the file to your Downloads folder or a dedicated Contacts directory for easy access later. The file will be named something like Office365ContactsExportYYYYMMDD.csv.

Use Excel's Find and Replace (Ctrl+H) to clean up formatting issues. For example, replace multiple spaces with single spaces in the Name column. Save the cleaned version as a new file with Cleaned in the name, like Office365ContactsCleaned.csv.

To keep your exported contacts list current, set a monthly reminder to repeat Step 2-4. For power users, automate the process using Power Automate (formerly Microsoft Flow). Create a flow triggered by a recurring schedule that exports the CSV file directly to OneDrive or SharePoint.

Here's the thing—some contacts may change roles or leave companies between exports. Always verify the latest Job Title and Company fields before using the exported data for outreach. I like to highlight these updates in yellow for quick review.

Tips & tricks for perfect Office 365 suggested contacts list export

Here's what nobody tells you about making this process smoother—and avoiding those frustrating last-minute surprises.

Browser Matters: I've found Chrome and Edge handle the export process most reliably for Office 365. If you're using Firefox or Safari, you might encounter occasional download delays in Step 3. Clear your cache beforehand—this prevents corrupted file issues that can happen when old session data interferes with the export dialog. For power users, I recommend using Chrome's Incognito mode to avoid any extension conflicts that could disrupt the process.

Filter Strategy: In Step 2, I suggest using the search filter to narrow by "work" or "colleague" before exporting. This prevents bloated files that include personal contacts or outdated entries. Pro tip: Add a secondary filter for "last email within 6 months" to focus on active professional connections. This targeted approach creates a cleaner, more relevant export that's perfect for networking outreach or CRM imports.

CSV Cleanup Shortcut: After exporting in Step 4, use Excel's "Remove Duplicates" tool (Data tab) before manual cleaning. This catches obvious duplicates that often slip through from shared calendars or group memberships. I also recommend adding a custom column for "Last Updated" by combining the "Job Title" and "Company" fields—this helps identify stale entries at a glance. Save your cleaned file with a timestamp in the name (e.g., "Office365ContactsCleaned_20240515.csv") for easy version tracking.

Automation Pro Tip: For the optional Step 5 automation, I've built a Power Automate template that doesn't just export but also sends the cleaned CSV to your OneDrive with automatic email notifications. The secret? Use the "When a schedule is triggered" connector set to run every 30 days at 9 AM—when most offices are quiet. This ensures your contacts list stays current without manual effort, and the automated email includes a summary of new/updated contacts since the last export.
