It was established that logging was NOT enabled within Outlook (Options | Advanced | Enable troubleshooting logging – unchecked), and in order to prevent the log files being generated, we had to create the following registry keys:
Ensure no Office applications are running, then launch Registry Editor (regedit.msc) and add the following as required:
[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\Access\Logging]
“DisableDefaultLogging”=dword:00000001
[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\Excel\Logging]
“DisableDefaultLogging”=dword:00000001
[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\Outlook\Logging]
“DisableDefaultLogging”=dword:00000001
[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\PowerPoint\Logging]
“DisableDefaultLogging”=dword:00000001
[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\Publisher\Logging]
“DisableDefaultLogging”=dword:00000001
[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\Word\Logging]
“DisableDefaultLogging”=dword:00000001
You can add one or more of these depending on which application(s) are causing the main problem. Note that the full path didn’t exist so some keys had to be created.
