Outlook-SharePoint Integration Software

Save emails to SharePoint, access files, and manage M365 content — without leaving Outlook.

harmon.ie adds a SharePoint sidebar directly inside Outlook. Your team can save emails and attachments to SharePoint with drag-and-drop, browse and open SharePoint files without leaving their inbox, and attach documents to outgoing emails as secure links. Everything stays inside Microsoft 365 — no additional servers, no external infrastructure.

Your files are in SharePoint. Your team is in Outlook.

Most organizations store content in SharePoint. Most people work in Outlook. That gap — between where content should live and where people actually work — is where collaboration breaks down, compliance fails, and SharePoint adoption stalls.

The consequences are predictable:

Employees save emails manually — or don't bother. Copying emails from Outlook into SharePoint requires switching applications, navigating folder structures, and adding metadata by hand. Most people don't do it consistently. Many don't do it at all.
Critical correspondence stays locked in personal inboxes. Emails that never reach SharePoint are invisible to colleagues, inaccessible to compliance tools, and lost when the sender leaves. One municipal government unlocked nearly 500,000 emails from staff inboxes in their first deployment year.
SharePoint adoption stalls because the interface isn't where people work. Asking employees to leave Outlook and navigate SharePoint in a browser is asking them to change how they work. Most won't.
IT invests in Microsoft 365 governance tools that only work on content that's actually been filed. Purview retention labels, sensitivity labels, and DLP policies don't apply to emails sitting in personal inboxes.

The fix isn’t a new platform or a training program. It’s bringing SharePoint to where your team already is.

harmon.ie connects Outlook and SharePoint — in both directions.

harmon.ie integrates SharePoint directly into Outlook as a sidebar panel. From inside their inbox, users can save emails to SharePoint, access and open SharePoint files, search across Microsoft 365, and share documents as secure links — without opening a browser or switching applications.

The integration works in both directions: emails flow from Outlook into SharePoint, and SharePoint content is accessible from Outlook. Automatic metadata maps email headers to SharePoint columns at the point of saving, so records are structured and searchable from day one.

Why organizations choose harmon.ie for Outlook-SharePoint integration

SharePoint lives inside Outlook — no context switching

harmon.ie runs as a sidebar inside Outlook — the application your team uses all day. Users access SharePoint without opening a browser, learning a new interface, or changing how they work. SharePoint adoption happens because it requires nothing new.

“Our users usually don’t know they’re using SharePoint; all they know is harmon.ie.” — Mike Miller, Missouri DOT

Built for compliance from day one

Emails saved through harmon.ie land in SharePoint where your retention labels, sensitivity labels, and governance policies already apply. harmon.ie works alongside Microsoft Purview — not instead of it. The filing step is simplified; the governance is unchanged.

Drives SharePoint engagement without a training program

When saving an email takes a drag-and-drop from within the application people already use, they do it. Organizations consistently report zero-training rollouts.

“Adoption was smooth. We didn’t do any training, we simply post training videos on our Streams site in Teams and our workers self-educate.” – Cesare D’Amico, IT Manager, DRASS

“harmon.ie makes the entire process of document handling easier for the employee, so that use of the SharePoint server has increased massively.” – Atilla Kücük, IT Division Manager, Leonhard Weiss

Works across every Outlook version

New harmon.ie supports Outlook for Windows (new Outlook), Outlook for Windows (classic), Mac, and Web.

harmon.ie Classic supports Outlook for Windows (classic) and SharePoint on-premises. A single license includes both products.

Proven at enterprise scale

Bosch deployed harmon.ie to 360,000 users and measured a 70% improvement in email management efficiency.

ESDC Canada migrated 32,000 employees to Microsoft 365 in three months using harmon.ie for email filing. These aren’t pilots — they’re full-scale, production deployments.

Your data never leaves Microsoft 365

harmon.ie is a client-side application — no server, no backend, no external storage.

Emails go directly from Outlook to your SharePoint, Teams, or OneDrive tenant. harmon.ie never sees or stores your content. ISO 27001 certified.

Outlook SharePoint Integration — FAQ

What is Outlook SharePoint integration?

Outlook SharePoint integration connects Microsoft Outlook to SharePoint so users can save emails, access files, and search Microsoft 365 content without leaving their inbox. harmon.ie provides this integration as a sidebar add-in that works inside Outlook and connects directly to your SharePoint Online libraries, Teams channels, and OneDrive.

How does harmon.ie integrate Outlook with SharePoint?

harmon.ie installs as an Outlook add-in — a modern web add-in for New Outlook (deployed centrally via the Microsoft 365 Admin Center) or a COM add-in for Classic Outlook. It adds a sidebar panel that connects to your Microsoft 365 tenant via Microsoft Graph API. From there, users can drag emails into SharePoint libraries, browse files, search across M365, and attach SharePoint documents to emails — all without leaving Outlook.

How do I connect SharePoint to Outlook? How do I link SharePoint to Outlook?

The easiest way to connect SharePoint to Outlook is with harmon.ie. Once installed, harmon.ie adds a sidebar panel to Outlook that links directly to your SharePoint Online libraries, Teams channels, and OneDrive — no manual configuration or URL entry required. Users sign in with their Microsoft account and their SharePoint locations appear automatically.

How do I access SharePoint from Outlook?

With harmon.ie installed, your SharePoint libraries appear in a sidebar panel inside Outlook. You can navigate the full folder structure, open and preview files, save emails by dragging them into the target library, and search across all SharePoint locations — without opening SharePoint in a browser.

Can I access SharePoint from Outlook without harmon.ie?

Microsoft provides basic SharePoint access via the Outlook sidebar, but without automatic metadata, email filing workflows, cross-Microsoft 365 search, or file attachment features. harmon.ie provides the full integration — including drag-and-drop filing, metadata automation, and email-specific features — that native tools don’t offer.

How do I save an Outlook email to SharePoint?

Open the harmon.ie sidebar in Outlook, navigate to the target SharePoint library, and drag the email from your inbox into the sidebar. harmon.ie saves the email to SharePoint and automatically maps To, From, Subject, and Date fields to the corresponding metadata columns. For outgoing emails, use Save & Send — a button that saves the email to a selected SharePoint location at the moment of sending.

Does harmon.ie work with the new Outlook?

Yes. New harmon.ie is a modern web add-in that supports Outlook for Windows (new Outlook), Outlook for Windows (classic), Outlook for Mac, and Outlook on the Web. harmon.ie Classic supports Outlook for Windows (classic). A single license includes both products.

Does harmon.ie support SharePoint on-premises?

Yes. harmon.ie Classic supports both SharePoint Online and SharePoint on-premises deployments. New harmon.ie supports SharePoint Online only. Organizations running a hybrid or fully on-premises environment can use harmon.ie Classic for the same email filing and metadata features.

Does harmon.ie work with Microsoft Purview?

Yes. harmon.ie handles the filing step — moving emails from Outlook into the right SharePoint or Teams location with automatic metadata. Microsoft Purview’s retention labels, sensitivity labels, and DLP policies apply to content once it’s in SharePoint. harmon.ie doesn’t replace Purview; it ensures content gets to where Purview can govern it.

How is harmon.ie deployed?

New harmon.ie is deployed centrally via the Microsoft 365 Admin Center or Intune — no local installation required, with automatic updates. harmon.ie Classic is deployed via Intune or SCCM. Both support pre-configured settings pushed to all users, so the integration is consistent across the organization from day one.
