# Invalid Email Address format

#### Summary

The error “Invalid Email Address format Email Address does not conform to the syntax rules of RFC 822” occurs during sync when the provided email address is not passing the RFC 822 syntax rules. This article explains how to identify and resolve the issue.

#### Problem

When syncing records from Salesforce (or any source system) to QuickBooks Online via DBSync, the sync fails with the following error message:

```
Error: Invalid Email Address format Email Address does not conform to the syntax rules of RFC 822. Supplied value:Â finance@lakeside.hants.sch.uk
```

This typically indicates that the format of the email address is not passing the RFC 822 syntax rules.

#### Applies To

* **Product/Service:** DBSync Cloud Workflow
* **Versions:** All versions supporting Salesforce-QBO integration
* **Operating Systems:** Platform-independent (Cloud-based)
* **Databases / Connectors:** Salesforce, QuickBooks Online
* **Applicable To:** “BillEmail” Address Mapping during Invoice Sync

#### Solution

**Prerequisites:**

* Admin access to DBSync
* Mapping access for the integration project
* Access to Salesforce (Source) instance if required

#### Steps

1. Log in to the Salesforce (source) instance and open the record that is failing to sync with the above error.
2. Make sure the provided email address is the right format i.e, it passes the RFC 822 syntax rules
3. Once the format of the existing email address is corrected, try to re-sync the record.

#### Root Cause

Since the provided email address did not conform to RFC 822 syntax rules, QBO returned the error message 

`Invalid Email Address format: Email Address does not conform to RFC 822 syntax`

which halted the sync.
