Suppress "Open Word?" dialog when default is to open documents in desktop app

[Ingeborg Hawighorst]

Hi,

In SP online libraries that are configured to open files in the desktop app instead of the browser, the users will still get a confirmation dialog when they click on a file.

Can this dialog be suppressed? 

We already have the setting in Excel/Word > Options > Advanced > Link Handling activated.

I found the solution. The message comes from the browser, not from SharePoint.

A registry entry can add a tick box to the dialog that people can tick if they don't want to see the prompt again.  These are the registry entries for Chrome and for Edge. They can be rolled out via GPO, but also applied manually. 

It worked for me in both Edge Chromium and Chrome.

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"ExternalProtocolDialogShowAlwaysOpenCheckbox"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge]
"ExternalProtocolDialogShowAlwaysOpenCheckbox"=dword:00000001
