Why do I see "Unverified App" when I synchronize my email?

Due to recent G Suite/Gmail changes, we recommend you make a simple change outlined below to your G Suite configuration to address this issue. Without following the whitelisting procedure below, you and your co-workers see an "Unverified App" warning when authorizing Email Sync.

Please forward the following instructions to your G Suite Super Administrator (or your IT team if you don’t know exactly who your administrator is).

  1. From the Google Admin Console Home page, go to Security and then API Permissions.
  2. Ensure that GMail API access is enabled. Disabling “All Access” or “High Risk Access” will disable Email Sync
  3. At the bottom of the list of apps, click the Trusted Apps link.
  4. Click Whitelist an App Add
  5. The Add App To Trusted List window opens. In the Select App Type list, select the "Web applications" option"
  6. Fill in the OAuth2 Client ID: 1833497015-bmp14o5q7fk0chm2gfb3bi3ruvd6s463.apps.googleusercontent.com
