Before a Google Workspace mailbox can be connected to OutreachFox, a Workspace administrator must mark the OutreachFox app as trusted in the Google Admin console. This is a one-time task per Workspace domain; once done, any user on that domain can connect their mailbox.

Prerequisites

  • Super admin (or an admin with API-controls rights) access to the Google Admin console for the domain.
  • The OutreachFox client ID, shown on the Google Workspace connection screen in OutreachFox (Mailbox → Connect Mailbox → Google Workspace).

Steps

  1. In OutreachFox, go to Mailbox → Connect Mailbox → Google Workspace. You are shown instructions to set up access in your Google Admin account. Click the provided link, or open admin.google.com in a new tab.

Why this matters

Google Workspace blocks third-party apps from accessing Gmail data through OAuth unless an admin has allowed them. Marking OutreachFox as Trusted lets the "Connect with Google" sign-in succeed and lets OutreachFox send and read mail on behalf of the mailbox. Without it, users see an "app is blocked" or "admin policy" error during sign-in.

Tips

  • If you have several Workspace domains, repeat these steps in each domain's admin console.
  • Apply the setting to the whole organisation (top-level OU) unless you deliberately want to restrict which users can connect.
  • Changes normally take effect within a few minutes; if the connection still fails, wait up to 24 hours as Google's policy cache refreshes.

Troubleshooting

  • App not found when searching the client ID — make sure you copied the full ID with no trailing spaces and searched under the OAuth App Name Or Client ID option.
  • "This app is blocked" during Connect with Google — the app is still marked Blocked or Limited; return to Manage App Access and set it to Trusted.
  • No API controls menu — your account lacks admin rights; ask a super admin.
