Ugh, just found Outlook is creating log files with extension .etl in the directory c:\Users\cseiler\Appdata\Local\Temp\Outlook DataSimilar to user at https://answers.microsoft.com/en-us/msoffice/forum/all/outlook-2016-creating-logs-in-temp-folder-when/80c6d938-a448-45f5-90d6-f23f27c3b819Sixteen GB(!) of logs since middle of last year. Why don't programs clean up after themselves, especially when logging is supposedly off. Response to user on above thread is that the amount of logging is normal. I really don't think mine is.
Sorry, directory is called "Outlook Logging."
Anyway, I just threw out all the logs over three months old. I can't even imagine needing a log from a week ago.
