How do you insert a hyphen in an email name. It says update then I put it in and it won't let me update. The name is O'Brian which is in the email. It won't let me save

We can modify and add acceptable characters to customer emails in your online account, toddvu35. Let me help you ensure you'll able to save and update their email information.

In QuickBooks, invalid characters can lead to server errors or other issues in the program. To help resolve this matter, make sure these only contain accepted characters from the list found in this article: Acceptable characters in QuickBooks Online. 

I'm also sharing a screenshot below for reference.

However, if the issue still persists, you can perform some troubleshooting steps to rule out the possibility of a browser issue. I'd suggest utilizing your QBO account in a private browser, then refer to these keyboard shortcuts:

• For Google Chrome browser: Ctrl + Shift + N
• For Mozilla Firefox browser: Ctrl + Shift + P
• For Safari browser: Command + Shift + N

If this information is populating successfully, you may go back to your default browser and clear its cache or use a different supported browser.

Furthermore, you can run specific reports to help you review your business' finances and customize them when needed.

I'm always ready to back you up if you require additional assistance managing data information in your account. Just keep me posted in the comments below. Stay safe and have a great weekend ahead!
