Saved Inboxes & Signatures
Team Cloud Sync

Stores templates, inboxes & signatures, and send history in a shared SharePoint/OneDrive folder so the whole team works from the same data. Paste a link to a folder everyone can edit. Access tokens are never uploaded; each person keeps their own.

○ Not connected
Your access token must also include Files.ReadWrite.All (consent in Graph Explorer, same place as Mail.Send). Sync runs automatically a few seconds after any change whenever a valid token is present.
Microsoft Sign-In (Permanent Auth)

Replaces token pasting. Sign in once with your work account and tokens renew silently in the background, so nothing expires on you. Two one-time prerequisites: an app registration in Azure (an IT task, about 10 minutes; instructions below) and hosting this file at an https:// address. Until both are done, pasted tokens keep working exactly as before.

Setup instructions for IT (Azure app registration)
1. Go to portal.azure.com → Microsoft Entra ID → App registrations → New registration.
2. Name: Five Stone Email Tool. Supported account types: Accounts in this organizational directory only.
3. Under Redirect URI select platform Single-page application (SPA) and enter the site address (origin) where the tool is hosted, e.g. https://tools.fivestonetax.com. For local testing you can also add http://localhost:8123.
4. After creating: API permissions → Add a permission → Microsoft Graph → Delegated → add Mail.Send, Mail.Send.Shared, Files.ReadWrite.All, User.Read → Grant admin consent.
5. Copy the Application (client) ID from the Overview page, paste it above, and click Save.
6. Exchange side: each user sending from a shared inbox (e.g. propertytax@) needs Send As permission on that mailbox (Exchange admin center → Recipients → the mailbox → Delegation → Send As). Anyone who already sends from it in Outlook has this.
