Hi there, @Eatititu.
Thanks for bringing this up in the QuickBooks Community page.
Can you tell us more about the update you're referring to? This way, we can provide you with the right response to address the issue. You can also provide your reference in this thread.
Currently, Thunderbird Email Client is one of the supported emails that can connect with QuickBooks Desktop. You can check out our compatible software in this article: System requirements for QuickBooks Pro or Premier 2020 and Enterprise 20.0.
If you want to set this up as your default email provider, simply follow these steps:
- Go to the Edit menu then choose Preferences at the bottom.
- A pop-up window will appear, select Send Forms.
- Under My Preferences tab, click Add to enter your email.
- Enter your email and select the email provider then click OK.
- You can now see your email under My Preferences, click OK to save changes.
You can refer to this article for more detailed steps: Connect your email to QuickBooks Desktop.
