For IT admins — deploy to your whole organisation

If you manage Microsoft 365, you can deploy Folder Suggest to all users (or specific groups) via the Admin Center.

Option 1 — Deploy from Microsoft Marketplace (recommended)

Sign in to the Microsoft 365 Admin Center
Go to Settings → Integrated Apps
Search for "Folder Suggest" in the Marketplace catalog
Click Get it now and follow the prompts
Under Assign users, choose Entire organisation, specific security groups, or specific users
Click Deploy

Option 2 — Deploy via custom manifest

Sign in to the Microsoft 365 Admin Center
Go to Settings → Integrated Apps → Upload custom apps
Select Office Add-in as the app type
Choose one of:
- Upload manifest file — use the download button above to get the file
- Provide link to manifest — paste this URL:
  https://app.foldersuggest.com/manifest.xml
Under Assign users, choose Entire organisation, specific security groups, or specific users
Click Deploy

Once deployed, users don't need to do anything. The Suggest Folder button appears automatically in their Outlook ribbon — no installation steps on their end.

What permissions does it request?

Folder Suggest requests two Microsoft Graph permissions:

Mail.Read — to read the email you have open and your folder names
Mail.ReadWrite — to move emails to the selected folder

All AI processing happens entirely on the user's device. No email content is transmitted to external servers. See the Privacy Policy for full details.

Troubleshooting

If you run into issues, see the Troubleshooting section on the Support page, or email [email protected].

Button doesn't appear after install — close and reopen Outlook; check the Home tab in the ribbon
"This add-in could not be installed" — make sure your browser isn't blocking app.foldersuggest.com; try a different browser
Add-in disappears after a few days — this usually affects manual (manifest) installs. Install from the Microsoft Marketplace instead for a persistent installation, or ask your admin to deploy it centrally
Using Outlook on iOS or Android? Mobile Outlook does not support add-ins — install via Outlook on the web or desktop instead
