Thanks for that, Paddy. I looked in the locations that were listed in your links and the subfolders under the appropriate headings were empty. While there are some things that I like about Outlook, there are others that I don't. Overall, I prefer Entourage.( Sadly, Entourage 2008 is 32-bit and won't work in the next macOS.) I can always start using Mail, of course, but I'll see how it goes. I stick with Office 365 because I much prefer Word to any other word processor that I have tried (and Pages is the worst).
