We're unable to sync some of your data because you have exceeded the total number of Salesforce Object Query Laguage (SOQL) queries allowed by Salesforce in a day.
This error is usually caused by a third-party system associated with your Salesforce account. For example, if you have an installed system that de-duplicates records in Salesforce, it might conflict with regular HubSpot syncing. Please try uninstalling any third-party systems that might be causing a conflict and try syncing again. If this error persists, please report it in Salesforce first by going to Your Name > Set Up > Monitoring > Debug Logs or Logs > Debug Logs and then call HubSpot Support.
