It all started when I upgraded my laptop from Office 2007 to Office 2010. I use Windows search function multiple times each day. It has been a fantastic way for me to find anything on my machine. However, after the upgrade to Outlook 2010, I lost the ability to preview Outlook email messages in file explorer. The search finds what I'm looking for, but I cannot preview the email in the preview pane., nor can I double-click the name to open the email. All other file types CAN be previewed and double-clicked as expected. I can do the same search within Outlook where it finds what I need, but searching within Outlook is horribly slow and practically unusable.
I have verified that the file associations are correct. The only suspicious thing I see is that the little icon next to the name looks like an Outlook 2016 icon: not what I'd expect to see.
Anyone have any suggestions?
