Hi there, MandyAZPCP.
Thanks for joining the Community. I'm here to share some information about the QuickBooks Desktop 2019 system requirements.
Microsoft Office 2010 and Office 2013, 2016, and 365 (including Outlook 2010 and Outlook 2013) on both 32 and 64 bit are currently supported in QuickBooks Desktop 2019. However, Office and Excel 2019 are currently unsupported.
For more in-depth information about the system requirements, you can check out this great article: QuickBooks 2019 and Enterprise Solutions 19.0.
This should point you in the right direction. Leave a comment below if you have other questions. I'm always around to help.
