EagleFiler opens AppleMail items in Outlook

Hello, sorry if this is a dumb request but i am trying out EagleFiler and have a problem. I created a library based on AppleMail. When i search the library and select/open an item it opens in Outlook, not AppleMail. i have looked through preferences and the user’s guide and can’t find anything that might help.

any suggestions?

thanks in advance for help!

EagleFiler opens files using whichever app is the default on your Mac for a particular file type. You can change this temporarily using the Open With command or permanently using the Always Open With command.
