Troubleshooting Common Connection Issues
"Account already exists in another workspace" Error
"Account already exists in another workspace" Error
This error means the account is already connected to another workspace, such as one you previously left or that has expired. Learn how to resolve this error here.
If you don't have a paid Instantly account, we can't disconnect the accounts to prevent abuse of free trials. You'll need to upgrade the new workspace to a paid plan.

Each Google account must be connected individually, even in the same workspace. The OAuth step will not automatically connect all email accounts under your Google Workspace to Instantly.
After configuring Instantly oAuth in your Google Workspace Admin console, follow the steps below to connect each Google email account in your Google Workspace: Connect Existing -> Google -> Option 1: OAuth method -> Login -> Select the email account you need to connect.
If the desired Google account does not appear in the selection list, click "Use another account" and proceed to log in to the specific account
