Quickbooks desktop 2018 is not recognizing Microsoft Office

Hi there, @206952.

Thank you for posting in the Community. Allow me to chime in to provide some insights about the technical support and provide some troubleshooting steps to resolve the issue.

Currently, free technical support is available if you have an active QuickBooks subscription. However, you can still find answers to your questions by visiting our QuickBooks support site for troubleshooting and other helpful "how-to" type information, find a local Proadvisor ( QuickBooks expert in your area that can help you) and of course, you can always access the QuickBooks Community to post your questions or view answers to questions posed by other QuickBooks users.

Let me share some steps to get you back on track. Let's start with setting up the Microsoft as your default program to make sure you'll be able to create a new workbook or send email in QuickBooks successfully. The following articles contain the steps on how to do this based on the version you're using.

• Change which programs Windows 7 uses by default
• Change default programs in Windows 10

After that, let's make Outlook the default email program.

1. Go to File tab, then select Options.
2. Under Start up options, choose Make Outlook the default program for E-mail, Contacts, and Calendar.

Then, let's verify the email service is set up in your QuickBooks Desktop. Once done, try to create the workbook and send email in QuickBooks.

Also, for additional support, it'd be best to get in touch with the Microsoft support first to see if there are restrictions set by the Admin. This could be the reason why you're getting this error.

That should get you back on track. I'm just a post away if you have any other questions about setting up Microsoft as default. I'll be happy to help you further. Wishing you and your business continued success.
