MacOS Catalina Mail side preview stopped working

Today I opened mail and found that the side preview was no longer working. If I disable the feature in View, I get the bottom preview, but if I enable side preview the bottom preview goes away and I do not get a side preview.

I have restarted mail. The results are the same. Is there some other option I need to enable to get this to work.

A family member was using the mail app earlier. Not sure if they did something to cause it to stop working.

Hi, welcome to the Apple Users Community.

Please take your mouse and hover over the edge on far right of the Mail window until a bold left facing arrow shows up, click and hold, then pull the window to the left. The preview should begin to show up, it may take a couple of attempts.

Best of luck
