Hello, everyone. I hear you, and I'm here to help.
Upon checking on my end, the investigation between Outlook and QuickBooks Desktop (QBDT) incompatibility has been closed as resolved. I can share some troubleshooting steps to get this fixed.
Even though software programs update their features now and then, it only requires a few edits of the settings to make them coordinate correctly. Just a heads up, I recommend asking for guidance from an IT expert before editing preferences within the software or your device. Let's begin with software compatibility troubleshooting.
- Close QuickBooks Desktop.
- Open the Windows Start menu.
- Type "QuickBooks" into the search. Then right-click the QuickBooks icon and select Open file location.
- In the folder, right-click the QuickBooks.exe file and select Properties.
- Select the Compatibility tab.
- Select to uncheck the Run this program as Administrator option. If the option is grayed out, select "Show Settings for All Users."
- Select Apply and then OK.
After this, I suggest sending a test email from QuickBooks to Outlook. When you still encounter the same error, you can proceed to the rest of the troubleshooting steps outlined within this article: How to fix "Error: QuickBooks is unable to send your email to Outlook".
For future reference, let me add this article about fixing data damage if you suspect data issues on your QBDT company file: Fix data damage on your QuickBooks Desktop company file.
