How do I preview a wav file in the new outlook without having to download the file?

The latest generation Microsoft Rich Media Player simply does not have a preview feature. If you go into Outlook > settings > Trust Center > Trust Center Settings > Attachment Handling > Attachment and Document Previews, you will see that Microsoft Rich Media Player is not there. The preview feature for WAV files does not work in Outlook because there is no preview app available to use!

The only solution is ot add Legacy Media Player which has a preview option. This has been documented in this thread before:

1. Control Panel > Turn windows Features on and off > Media Features > enable legacy media player (LMP)
2. Set legacy media player as your default app for WAV files

Unfortunately this causes a serious problem if you have OneDrive folders synced to your computer. When you try to rename a folder OneDrive tries to to sync the filename to the cloud every time you enter a character (not at the end of the name when you finish). As soon as you type 2 or 3 characters at normal speed the sync gets confused and the folder name starts blinking and goes crazy. This is a well known issue in other Microsoft forums.

This OneDrive issue only happens if LMP is installed. Removing legacy media player eliminates the OneDrive problem. I have no idea how LMP is connected to this issue but I've repeated the theory several times and it works. Remove LMP and the OneDrive folder rename problem stops. Install it and the folder problem returns.

For both Outlook preview and OneDrive to work correctly Microsoft will have to fix LMP (unlikely its an old program) or add a preview feature to Rich Media Player. Or maybe someone knows of an alternative media player that works with preview?

I just use the drop down menu/arrow on the attached file in Outlook and choose 'Quick Print' and pick video player. Works for me as I only use it a few times a month,

Sorry to hear that, which part didn't work (the steps or the potential admin script)?

What did you find when you looked at your default apps?

So is it something that Microsoft has pushed an update or something of some kind that has caused this issue is there any document that says when was this done

Thanks
