Error Message
If you see the following error when trying to log in to ExtendSync:
{ "error": { "code": "", "details": "You are not authorized to perform this." } }
It means your NetSuite role is missing a required permission needed for ExtendSync authentication.
This is resolved by updating your NetSuite role permissions.
How to Fix the Error
Ask your NetSuite Admin to update the permissions for the role you are using to log in.
Go to
Setup → Users/Roles → Manage Roles → Edit (or Customize)Open the Permissions → Setup subtab.
Add the following permission (if not already present):
Log in using Access Tokens and set Level to Full
Click Save.
Ask the user to:
Close Outlook completely
Reopen Outlook
Log in to ExtendSync again
Why This Happens
ExtendSync uses NetSuite's Three-Step Authorization flow, which requires Token-Based Authentication (TBA).
If the role does not have Log in using Access Tokens, NetSuite will block authentication and return this error.
