Questions about med.unc.edu
UNC School of Medicine email questions, answered from this data
Every answer comes from the numbers on this page, 90 days to November 6, 2026.
What email domain does UNC School of Medicine use?
med.unc.edu. Its mail is routed through Microsoft 365 (med-unc-edu.mail.protection.outlook.com), with SPF published and DMARC published, checked November 2, 2026.
What is the most common med.unc.edu email format?
[email protected]: 55–63% (95% range 45–72%) of the 95+ distinct med.unc.edu addresses mailfloss verified in the 90 days to November 6, 2026. Next: "one word, not a recognised name" at 30–36%.
Is med.unc.edu a catch-all domain?
No. In mailfloss's checks (latest October 23, 2026), med.unc.edu mostly rejected addresses that do not exist, so it is not a catch-all domain. Because med.unc.edu mostly rejects mailboxes that do not exist, a permanent (5xx) "mailbox does not exist" or "account disabled" answer from it is reliable, and those addresses can come off your list; a 4xx answer is temporary, so retry it. An accepted answer is strong but not certain evidence that the mailbox exists. A full inbox or a busy mailbox is temporary, so recheck those later.
Do med.unc.edu addresses bounce?
Of mailfloss's med.unc.edu verifications in the 90 days to November 6, 2026, 76–79% were accepted, 12% were rejected and 11% got no clear answer.
How do I find or check an email address at med.unc.edu?
Build it from the person's name in the most common format, [email protected], then verify it before you send: mailfloss asks the med.unc.edu mail server about that exact address and reports what it answered. Because med.unc.edu is not a catch-all domain, a clear answer means what it says. Verify one now.
Does UNC School of Medicine use Google Workspace or Microsoft 365?
Microsoft 365, the mailbox provider on mailfloss's record. Its published MX record points there too, going by its public mail records as of November 2, 2026, with no security gateway in front of it.
