Moonlight 365 Filer lets you file emails, attachments, Word, Excel, and PowerPoint files directly to SharePoint - fast, secure, easy to use.

The newly enhanced Moonlight 365 Filer brings together the power of email filing and direct document filing—all in one clean, intuitive experience. Whether you're working in Outlook, Word, Excel, or PowerPoint, Moonlight 365 Filer puts SharePoint right at your fingertips, helping you keep your organization’s content structured, searchable, and shared. In addition, the Filer also adds the feature of attaching files stored in SharePoint to your outbound email.

File Anything. Open Anything. Work Anywhere.

Pin your favorite SharePoint sites inside Outlook, Word, Excel, and PowerPoint and file your content with confidence.

  • In Outlook, save attachments, entire emails, or both directly to the right SharePoint site in just a few clicks.
  • In Word, Excel, and PowerPoint, open files stored in SharePoint or save new versions back—using a clean, easy-to-understand interface that removes guesswork.

Once saved, your colleagues can access the email or file from SharePoint whenever they need it, without digging through inboxes or shared drives. Better yet, find the content using the Moonlight 365 Content Navigator!

Boost Productivity

With just one click, browse or search your SharePoint sites and instantly save your email, attachment, or Office file to the right place—no extra windows, no confusing steps. Streamlined filing equals minutes saved every day.

Easy to Use - Out‑of‑the‑Box Simplicity

Select your email, click the Filer button, choose a SharePoint site or folder, check the box, and save. In Office apps, the experience is just as simple: click to open or save directly from SharePoint using the integrated Moonlight 365 Filer interface.

Seamless Integration.

Because Moonlight 365 Filer is deployed directly inside your Microsoft 365 tenant, installation is effortless. Just open your Microsoft 365 Add‑In Store, install it, and go! No external services. No complicated on-boarding. And because it lives inside your tenant, it can be enhanced or customized as your needs evolve.

Filed Email Indicators

As soon as you file an email, the Filer adds a color category so you always know what’s been saved—no duplicate work, no guessing.

Attach SharePoint Files/Documents to Email

Filer developers recently added the ability for users to attach documents or files that are stored in SharePoint to your outbound email with a couple of clicks.

Secure by Design

Moonlight 365 Filer runs entirely within your organization's Microsoft 365 environment and uses Azure services exclusively inside your tenant.
That means:

  • No external processing (no security risk)
  • No third‑party data handling
  • All emails, files, and metadata stay securely inside your organization
  • Your data never leaves your control
