Fix GoHighLevel 2-Way Email Sync Permissions

If your emails are failing to sync, this step-by-step guide will help you fix the issue quickly. While this article focuses on GoHighLevel, similar concepts apply to other work platforms like ClickUp where API and permission scopes matter for integrations. Below you will learn why the error appears and how to correct permissions in Gmail and Outlook so your 2-way email sync works reliably.

What Causes the GoHighLevel 2-Way Sync Error?

When 2-way email sync fails in GoHighLevel, you may see an error that mentions insufficient permission for 2-way sync. This means your email provider did not grant all the scopes GoHighLevel needs to read, send, and manage messages on your behalf.

Common causes include:

  • Authorization was completed with limited or outdated permissions
  • The email account owner changed security settings after the initial connection
  • Admin policies for Google Workspace or Microsoft 365 removed required scopes
  • Tokens expired and did not refresh correctly

To restore 2-way sync, you must re-authorize the email account with the proper permissions so GoHighLevel can access the inbox and sent items.

How GoHighLevel 2-Way Email Sync Works

2-way email sync in GoHighLevel allows you to manage emails directly in your CRM while staying fully in sync with your email provider. When it is configured correctly, you can:

  • Send emails from within GoHighLevel and see them in your regular Sent folder
  • Receive inbox messages and view them as conversations on contacts
  • Track replies and maintain accurate timelines in each record
  • Keep your team aligned on customer communication across tools

If 2-way sync permissions are incomplete, GoHighLevel cannot reliably read or send messages, and email logging will break.

Fixing GoHighLevel Gmail 2-Way Sync Permissions

If you connected a Gmail or Google Workspace inbox and see an insufficient permission error, follow these steps to fix it.

Step 1: Remove Existing Gmail Connection in GoHighLevel

  1. Log in to your GoHighLevel account.
  2. Go to the settings area where your email accounts are managed.
  3. Locate the Gmail account that shows a sync failure.
  4. Disconnect or remove this email connection so you can start a clean authorization.

Removing the old connection ensures that new, correct permissions will be requested the next time you connect.

Step 2: Check Gmail Account Access

  1. Open your Google Account settings in a new browser tab.
  2. Navigate to the section that manages third-party access (often called “Security” > “Third-party access”).
  3. Find the existing GoHighLevel app authorization, if present.
  4. Remove or revoke access for GoHighLevel so the integration can request fresh scopes.

This step clears any outdated or partial permissions that may be blocking full 2-way sync.

Step 3: Reconnect Gmail to GoHighLevel

  1. Return to GoHighLevel and go back to the email integration settings.
  2. Choose to add or connect a Gmail / Google Workspace account.
  3. Select the correct Google account when prompted.
  4. On the Google consent screen, review the list of requested permissions.
  5. Allow all required scopes so GoHighLevel can read, send, and manage your email messages.

Do not deselect any required permission; limiting scopes here is a common reason the insufficient permission error appears.

Step 4: Confirm Gmail 2-Way Sync in GoHighLevel

  1. After successful authorization, check the email account status in GoHighLevel.
  2. Send a test email from GoHighLevel to a personal address.
  3. Reply from the external account and confirm the reply appears on the related contact conversation.
  4. Verify that the email also shows correctly in your Gmail inbox and Sent folder.

If messages flow both ways, the permission issue is resolved for your Gmail account.

Fixing GoHighLevel Outlook or Microsoft 365 2-Way Sync

If you use Outlook, Exchange Online, or Microsoft 365 with GoHighLevel and encounter the insufficient permission error, follow these steps.

Step 1: Remove Existing Outlook Connection in GoHighLevel

  1. Sign in to your GoHighLevel dashboard.
  2. Open the email or integrations settings where your Outlook account is listed.
  3. Disconnect or delete the Outlook / Office 365 connection that is failing.

This prepares your account for a clean re-authorization with the right access.

Step 2: Revoke GoHighLevel Access in Microsoft

  1. Open your Microsoft account or Microsoft 365 account security page.
  2. Go to the section for Apps and services that have access to your data.
  3. Locate the GoHighLevel app authorization.
  4. Remove or revoke its access so that new permissions can be granted.

If you are on a corporate Microsoft 365 tenant, you may need an IT admin to confirm that third-party apps like GoHighLevel are allowed.

Step 3: Reconnect Outlook to GoHighLevel

  1. Return to GoHighLevel and open the email integration settings again.
  2. Start a new connection for Outlook or Microsoft 365.
  3. Sign in with the correct Microsoft account when prompted.
  4. On the Microsoft permission screen, carefully review the requested access.
  5. Accept all required permissions so GoHighLevel can read, send, and synchronize your emails.

Denying or limiting any requested permission will usually result in another insufficient permission error.

Step 4: Verify Outlook 2-Way Sync in GoHighLevel

  1. Check the connection status in your GoHighLevel email settings.
  2. Send a test email from inside GoHighLevel to another inbox.
  3. Reply from that other inbox and confirm the conversation appears on the contact record.
  4. Ensure the outgoing and incoming messages show correctly in Outlook as well.

Once you see accurate syncing across both tools, the permission problem is fixed.

To minimize future permission issues with GoHighLevel 2-way email sync, use these best practices:
