Rob Macedo, KD1CY, alerts us to problems receiving where Microsoft is intentionally blocking SKYWARN announcements. The full details are at https://wx1box.org/2023/08/02/special-announcement-charter-hotmail-msn-outlook-email-addresses-blocked-from-receiving-skywarn-announcement-emails/.
I have also noticed a problem where club mail to addresses at outlook.com have silently disappeared, so I will be contacting the few current members who may have be affected.
