Hi All,

I have installed on my local laptop an Office 2016. I use my Outlook 2016 as my email client and in order to organize my emails I MOVE them to a folder I create my documents so I can organize them without the need to go through my archives to try to find them.

Now, when I click on those emails messages locate on my folder, that is on a FOLDER out site Outlook 2016, I got this message all the time. (see screenshot attached).

I did make in Control Panel "default programs" Outlook as my default client. Well, I only have Outlook as a mail client anyway. When I click on the email messages on the folder this message still popping up all the time. Can you help to get rid of this message?

Can you please advise?

Office 2016 32 bit or 64 bit?

If you have installed 64 bit Office 2016, it is the default behavior.

This issue occurs when you have the 64-bit version of Microsoft Outlook installed. The Windows preview host requires a 32-bit application previewer. When 32-bit Outlook is installed, it acts as the previewer. Without 32-bit Outlook installed, there is no previewer available for .msg files.

To work around this issue, use one of the following methods.

Method 1: Disable the Windows Explorer Preview Pane, and open the .msg file to view it in Outlook

Open Windows File Explorer.
On the View tab, click Preview pane to disable it.
To view the .msg file, double-click it to open it in Outlook.

Method 2: Use 32-bit Outlook

If you prefer to preview .msg files in Windows File Explorer, install the 32-bit version of Outlook instead of the 64-bit version.

Good call, Jackie Man about Office versions. I didn't know that about the 64-bit version.

Mallony, it may seem to make sense to install the 64-bit version on your 64-bit OS, but even Microsoft recommends choosing the 32-bit Office. There are more add-ins available and, as Jackie mentioned, viewers.

I use MS Outlook 2016 64 bit version also in my Office PC and it is the same error if I open .msg file from Windows Explorer directly.

The only difference is I seldom open or save .msg files as it is just too troublesome to uninstall and reinstall MS Office 2016 32 bit version.
