Windows mail "Verbose diagnostic logging"

Not an answer, just another user facing the same problem.

Why can't Microsoft answer this question. The same query has been asked for several years. I have one email account that for some reason stopped sending output, messages hang in the Outbox. I have tested on my laptop with Windows Mail & Calendar and Outlook with the same result. Messages can be sent from Outlook on my phone or if I log into by email account on the internet providers web page.

Turned on Verbose diagnostic logging in Windows Mail to troubleshoot the problem, but what good does that do I you can't divulge the location this file might be written to. Previously tried deleting the account from Windows Mail and then re-adding the account with the same result.

For future searchers: I found it. After enabling the verbose diagnostic logging, an ETL file (HxmLog.etl) can be found in this directory:

%localappdata%\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\

You have to open that file in Event Viewer to see the logs.

I found this by using the Resource Monitor to see which files were opened by the process.
