Microsoft Dynamics SL 2018 is installed on Windows Server 2016 x64
SharePoint Online Document Library is mapped on Drive Z: and it can be found and access along with the local drive C: on "This PC"
On Microsoft Dynamics SL Application under System Administration > Attachment Configuration
The mapped drive is not available on "Existing Folder Location" but on other app it is available like Microsoft office word
Any Idea? anyone. thanks
