Install Folder Suggest

No app store required — install directly from Outlook in about 2 minutes

For individuals — install yourself

Step 1 — Download the manifest file

📄
manifest.xml Folder Suggest add-in manifest
↓ Download

Step 2 — Add it to Outlook

Outlook on the web, New Outlook for Windows, or Mac

  1. Sign in to Outlook on the web (outlook.live.com or outlook.office.com)
  2. Click the Settings gear (top right) → View all Outlook settings
  3. Go to Mail → Add-ins
  4. Under My add-ins, click + Add → Add from File
  5. Select the manifest.xml you downloaded and click Install
  6. A Suggest Folder button will appear in your toolbar when you open an email
Mac users: install using the web steps above — the add-in syncs automatically to your Mac desktop app. Close and reopen Outlook if the button doesn't appear within a minute.
You may see a security notice saying the add-in "is not from Microsoft AppSource." This is expected — click Install (or OK) to continue. No email data is sent to external servers.
Don't see the "Add from File" option? Your organisation's IT policy may have disabled individual add-in installs. Ask your IT admin to deploy it using the instructions below — it takes about 5 minutes and the button will appear automatically for you.

Classic Outlook for Windows (traditional ribbon app)

  1. Go to the Home tab and click Get Add-ins (or Store on older versions)
  2. Click My Add-ins at the top of the panel
  3. Scroll to Custom Add-ins at the bottom → + Add a custom add-in → Add from File
  4. Select the manifest.xml you downloaded and click Install
  5. The Suggest Folder button appears in the ribbon on the Home tab
Already installed via Outlook on the web? The add-in syncs automatically to desktop Outlook — no separate installation needed.

Microsoft 365 Admin Center

  2. Go to Settings → Integrated Apps → Upload custom apps

  5. Under Assign users, choose Entire organisation, specific security groups, or specific users
