I’m “unusual” in that I’m a morning person, not by choice. Once I’m awake, I’m awake. Could be 6:30AM, could be 4AM. My mind just starts racing and I know going “back to sleep” isn’t happening. These days I tend to fall asleep easily (although, not so much in the past), but there’s no going back when I wake up, so on an average night I’m nodding out before 10. I had a sleep study done, and for me it was a huge waste of money, i.e. " You don’t have sleep apnea. You don’t need tranquilizers. See ya."

Yo, how’d you get in my home lab?

If you want free options, I often use MailEnable and hMailServer in lab environments. Also a free Azure developer trial includes some M365 licenses, and it pretty much always auto-renews every 90 days (I’ve had a few tenants going for YEARS now)
