How to default open a .MSG directly in Outlook instead of first downloading it (In SharePoint O365)

Question

_{Tuesday, January 24, 2017 10:18 AM}

Hello,

How can i default open a .MSG directly in Outlook instead of first downloading it , this is in SharePoint O365.

In the on premise version i found different options, change browser file handling in de app management  or ISS manager in combination with powershell. Both options don't apply to the online version.

Is there an option to do so? or perhaps a javascript per example?Anyone got an idea?

Regards, Rob

Hi,

SharePoint online provides a new experience UI. You can preview the email file in the browser when you click .msg file.

If you’re using classic UI mode, IE will give a prompt dialog to open/save/cancel. The file will be opened in Outlook if you click Open button.

In SharePoint on-premise environment, the prompt dialog doesn’t contain Open button if you don’t change any settings. It will occur after you add .msg to MIME Types in IIS and set Permissive for web application.

Thus, opening .msg file should work as expected in SharePoint online. If it doesn’t work fine in your SharePoint site, please make sure that you’re using IE 32bit and add SharePoint site in trusted sites.

Hi,

It’s not possible now.

The preview of .msg is only supported in new experience UI in library now.

Thanks,
