Hello juVielL,

This issue is NOT solved and

unfortunately, I'm not sure if you thoroughly read the previous poster's question I responded to regarding QuickBooks 2018 hanging when attempting to access the "File > Preferences > Send Forms" setting in QuickBooks 2018 Desktop Pro.

Just clicking on that setting causes QuickBooks to hang and become completely unresponsive. The enduser then has to force close QuickBooks via Windows Taskmanager. 

In addition to hanging when accessing this setting, the application also does the same thing when sending the first email (invoice, estimate or receipt) of the day. After force-closing and reopening the application, emails will send normally, but accessing the Send Forms setting still causes random hangs after the force-close and reopen of the application.

The application also randomly becomes unresponsive while the user is performing other tasks, and has only recently started happening. These hangs appear to coincide with the installation of the latest maintenance release, but I cannot absolutely confirm that is the source of the behavior.

Also, I'm not sure if this has any impact on the issue but I thought I would at least mention it. Windows Application Events repeatedly lists Error 5 for QuickBooks 2018 on initialization. The network share path and QuickBooks files contain no whitespace and are fully accessible to the workstations and Windows user accounts experiencing the issue.

I am a seasoned IT consultant, and have 
already performed numerous steps to correct the errors on both workstations experiencing the issues.

Here are specifications for the hardware, OS and installed applications.

HP 24" AIO Touch
Intel Core i5 7400T 2.40Ghz
12GB Ram
2.0TB SSD

Windows 10 Home 64-bit v1903
Windows Defender AV and Firewall
Office 365 Business (Access, Word, Outlook, Excel, PowerPoint, Publisher, OneDrive Business, Skype Business, Teams)
Internet Explorer 11
Mozilla Firefox
QuickBooks 2018 Desktop Pro

Users are using Google Mail accounts to send mail on their behalf from within the application.

The operating system and all installed applications are the latest versions with all applicable updates installed.

Here are the troubleshooting steps I have performed to date:

1. All user accounts are local administrators and QuickBooks is not being forced to run as an administrator.

2. All users have third-party app access enabled on their Google accounts.

3. Ran SFC / Scannow and DISM /Online /Cleanup-Image /RestoreHealth on both Windows 10 workstations. Only minor image inconsistencies were found and repaired on both workstations.

4. Performed a full online repair of Office 365 Business. (Emails send correctly via all installed Office apps that have the capability to do so.)

5. Performed Quick and Full product repairs of the application via the QuickBooks Tools Hub.

6. Installation repair of the QuickBooks desktop application via Windows Programs and Features.

7. Clean uninstall via the QuickBooks clean install utility and fresh installation of QuickBooks 2018 Desktop.

8. Cleared Internet Explorer cache and verified IE 11 is functioning properly.

9. Scan and repair of the company file via QuickBooks File Doctor. Only minor inconsistencies found in the file.

10. Permissions check on network file share and QuickBooks files. 

11. Deleted and recreated the network share, set appropriate share and user permissions. Verified QuickBooks Server Manager is functioning normally.

12. Created a new QuickBooks user account for one of the users with the issue. The other user is Admin, so no way to create a new account (at least nothing that is published by Intuit for public consumption). 

Which raises another question; How do I correct user issues with Admin if I cannot delete and recreate the account? However, I'll save that question for another time, unless it is pertinent to the current issue.

Please let me know as soon as possible what our next steps are to resolve these issues as they are adversely impacting daily operations of the business.
