error email: Invalid Email Address formatEmail Address does not conform to the syntax rules of RFC 822. Supplied value: XXX.XXXX@XXXXXXXX.COM.SGNeed to know whats wrong?

I’ll explain the common reasons you might see an email address format error in QuickBooks Online (QBO) and how to fix it, Stylusyeo.

The error message Email Address does not conform to the syntax rules of RFC 822 is just a technical way of saying the email address you entered doesn’t follow the standard guidelines for a valid email address format.

Here are the most common reasons for this error:

1. Extra Spaces: Look for any extra spaces before or after the email address. For example, user@domain.com or user@domain.com. These spaces are subtle and easy to miss.
2. Invalid Characters: Email addresses are limited to specific characters. Symbols like commas, semicolons, or other special characters (aside from _, -, or .) are not allowed in most parts of the address.
3. Multiple "@" Symbols: An email address should only include one "@" symbol.
4. Incorrect Domain: Double-check the domain name (e.g., XXXXXXXX.COM.SG) to ensure it’s spelled correctly and doesn’t contain invalid characters or a missing top-level domain (.COM, .ORG, .SG, etc.).
5. Missing Parts: Verify that the email address isn’t missing essential elements like the username, the "@" symbol, or the domain.
6. Incorrect Order: The proper format for an email address is username@domain.tld (e.g., name@company.com).

Here’s how you can troubleshoot this error:

• Carefully retype the email address instead of copying and pasting it, as this might introduce hidden spaces or formatting issues.
• Double-check the spelling of both the username and the domain name.
• Confirm that the email address is valid. If possible, send a test email to the address from a different account to ensure it’s active and accurate.
• Try using a different email address. For example, if you’re sending an invoice, test it by sending it to your own email address first. This can help determine if the issue is specific to the recipient's email.

By reviewing these points, you should be able to identify and fix any problems with the email address format. If you need further assistance with QBO, let us know. We’re always here to help!
