Overview

In order for the Sublime Platform to access mail from your tenant programmatically, you must create a new Azure app and authorize it for access. This is required so that only you have access to your mail, and not anyone else, including the Sublime team.

📘

Tenant admin

You must be a tenant admin to authorize this app for all users on your domain.

After completing the steps below, you'll copy over the following to add the message source in Sublime:

  • Application (client) ID
  • Directory (tenant) ID
  • Client secret

Steps

  1. Login to https://portal.azure.com
  2. Search for App registrations
  1. Click + New registration
  1. Enter "Sublime Platform" for the app name. Leave the other defaults (Single-tenant, no Redirect URI). Click "Register".
  1. Copy the application (client) ID and the Directory (tenant) ID over to the Sublime Platform setup
  1. Click View API permissions and then + Add a permission
  • Select Microsoft Graph
  • Select Application permissions
  • Choose Mail.ReadWrite, User.Read.All, Group.Read.All, and Domain.Read.All
  • Click Add permissions
  1. Then, Grant admin consent for your domain. Note that if this button is greyed out for you, you may need to have a Domain Admin grant the consent.

You should see green checkmarks like this:

  1. Navigate to Certificates & secrets in the sidebar
  1. Create a new Client secret. Enter "Sublime Platform" for the description and choose "24 months".
  1. Copy the client secret "Value" over to the Sublime Platform setup.

:tada: That's it!
