Error: Attachment of Email Failed Due to Authorization Token Has Expired

ExtendSync Google | Fix “Authorization token has expired” when saving emails to NetSuite

If you see the error below while attaching an email to a NetSuite record, the Google authorization used by ExtendSync has expired and must be re-granted.

Error Message

Attachment of Email(....) to record failed due to Authorization token has expired. Please contact your Administrator to regrant the access

Why This Error Happens

ExtendSync relies on a secure Google authorization to attach emails to NetSuite.
Over time, this authorization can expire due to:

  • Security policy updates

  • Credential changes

  • Long periods without reauthorization

When the token expires, ExtendSync cannot complete the attachment action.

How to Resolve the Error

These steps require both a NetSuite Administrator and a Google Workspace Admin.

Step 1: Open CloudExtend Setup in NetSuite (NetSuite Admin)

  1. Log in to NetSuite as an Administrator.

  2. Navigate to:
    ​Setup → Custom → Celigo CloudExtend Setup
    ​

Step 2: Re-Grant Google Access (Google Workspace Admin)

  • If a Google authorization pop-up appears, click Allow Access and complete the consent as the Google Workspace Admin.
    ​

If no pop-up appears:

  • Click the authorization link shown in Step 1 on the setup page to manually trigger the consent screen.

  • Complete the consent as the Google Workspace Admin.
    ​

Once access is granted, click Next to continue.

Step 3: Review Licenses and Finish (NetSuite Admin)

  1. Continue through the wizard until you reach User Licenses.

  2. Confirm the appropriate users are selected and licensed.

  3. Click Next, then Finish.
    ​

This completes the re-authorization.

✅ Verify the Fix

After re-granting access:

  1. Ask the affected user to refresh Gmail.

  2. Open the ExtendSync panel.

  3. Attempt to save an email attachment to a NetSuite record again.

The attachment should succeed without error.

📝 Notes & Best Practices

  • Re-authorization is non-disruptive and does not change user data.

  • If your organization enforces strict security policies, periodic re-authorization may be expected.

  • If multiple Google domains or admin roles exist, ensure the correct Google Workspace Admin completes the consent.
