Resolving Insufficient Permission for Two-Way Email Sync

About the Insufficient Permission Error

You may encounter an error stating "Insufficient Permission for 2-Way Sync" when your CRM can no longer access your connected email account (such as Gmail or Outlook). This happens because the necessary permissions have been lost or revoked, preventing two-way email synchronization.

Before You Begin: Confirm the Error

This guide applies if you see one of these specific messages:

• Email Failure: Insufficient Permission for 2-Way Sync
• Any error indicating your CRM lacks permission to access your connected inbox

Important: This article does not apply to other common email errors. If your error message is related to insufficient funds, authentication failure, exceeded email quotas, or domain verification issues, please refer to the appropriate documentation for those specific problems.

Why This Error Occurs

This permission error typically happens when the authorization link between your CRM and your email provider is broken. Common causes include:

• You or your email administrator revoked the CRM's access permissions.
• You changed the password for your email account.
• Your email provider's security policies have invalidated the existing connection token.
• The connected mailbox was manually disconnected or has expired.
• A security update from your email provider requires you to re-grant permissions.

How to Fix the Issue

Step 1: Access Email Services

Navigate to your CRM's Settings area and select Email Services. Locate the email account that is showing the error.

Step 2: Reconnect Your Email Account

If the account status indicates an error or requires attention:

1. Click the Reconnect button (you may need to remove and re-add the mailbox).
2. Sign in to your email account using the correct credentials.
3. Carefully review the permissions the CRM is requesting.
4. Select Allow to grant the necessary access.

Note: Granting all requested permissions is essential for two-way email sync to work correctly.

Step 3: Verify the Connection

After reconnecting, confirm the process was successful:

• Check that the email account now shows a Connected status.
• Send a test email to ensure it is delivered.
• Verify that replies to the email appear within your CRM's Conversations.

If the Problem Continues

If reconnecting the account does not resolve the issue, try the following:

• Disconnect the mailbox completely and then reconnect it again.
• Double-check that you are signing in with the correct email account credentials.
• If you use a business email (like Google Workspace or Microsoft 365), confirm that your administrator has not applied policies that block third-party app access.
• Attempt the reconnection process using your browser's incognito or private mode.

If the error persists after these steps, please contact CRM Support. When you do, provide the following information to help them assist you quickly:

• The email address that is affected.
• The specific error message you are seeing.
• Your email provider (e.g., Gmail, Outlook, etc.).
• The approximate date and time the error first started.

Frequently Asked Questions

Will reconnecting my email delete any existing emails?

No. Reconnecting only re-establishes the authorization. All your existing emails will remain safe and intact.

Why did this happen if it was working before?

Email providers often invalidate connection tokens after events like password changes, security updates, or policy changes by an administrator, which can break the link with your CRM.

Does this error affect both sending and receiving emails?

Yes. Without proper permissions, your CRM will likely be unable to send emails on your behalf or sync incoming messages and replies into the Conversations area.

Related Troubleshooting

If your error message is different, please consult the relevant guide:

• For insufficient email credits, see billing documentation.
• For SMTP authentication failures, review your SMTP setup.
• For domain verification issues, check your DNS and domain authentication settings.
