Setting up Microsoft 365 / Office365 as SMTP in QRACCESS
Connection details, how to get the credentials and exactly what to enter in the dashboard. Not sure which provider to pick? Start with the general SMTP guide.
Connection details
| Server (host) | smtp.office365.com |
| Ports | 587 (STARTTLS) |
| Username | the full mailbox (e.g. events@yourcompany.com) |
| Password | the mailbox password (or an app password if MFA is on) |
How to get the credentials
- An admin must enable “Authenticated SMTP” for that mailbox: M365 admin center → Users → Mail → Mail apps.
- If the mailbox uses multi-factor authentication, generate an app password in the account security settings.
- The sender configured in QRACCESS must be that mailbox or one of its authorised aliases.
What to enter in QRACCESS
In the dashboard: Settings → SMTP. Fill in Host and Port from the table above, pick the encryption to match the port (TLS for 587, SSL for 465), and enter Username and Password exactly as the table says — with some providers the “username” is a fixed word or an API key, not your email. Use a sender address on your verified domain and a recognisable sender name. Save, then use the test button with one of your own contacts before any bulk send.
Note: Microsoft limits: ~10,000 recipients/day and ~30 messages/minute — fine for medium-sized events. If Microsoft blocks the first sends as “unusual activity”, unblock from the admin center.
Deliverability: SPF and DKIM
Whatever the provider, verify your domain and publish the SPF and DKIM records it gives you: that is the difference between the inbox and the spam folder. Always run a single test before a bulk send.
