Microsoft 365 and Professional Email for SMEs
A professional email address on your own domain builds credibility and keeps your communications secure. Sentinel Infrastructure manages Microsoft 365 for SMEs. We do the initial setup and handle the Microsoft 365 migration from your old email provider, then stay on to manage licences and support your users.
Microsoft 365 set up right from day one
Microsoft 365 is powerful but it's not always simple to configure correctly. Misconfigured DNS records, wrong MX entries, or security settings left at default can cause email delivery issues and security gaps. Our certified team gets those settings right at the start, and we're still on hand afterwards as your team grows.

The industry standard for SME email and collaboration
Professional Email
Email at your own domain (name@yourbusiness.co.uk), with the reliability of Exchange behind it. Clients and prospects see a proper business address from the first message you send.
Built-in Security
Spam filtering, phishing protection, and MFA are built into Microsoft 365. We make sure they're switched on and configured properly, since the default settings leave gaps.
Team Collaboration
Teams handles video calls and messaging, SharePoint holds shared documents, and OneDrive gives each person their own file storage. It all works on desktop, mobile, and tablet.
They migrated all of our email accounts to Microsoft 365 with no downtime and no lost emails. Exactly what we needed.
Frequently Asked Questions

Yes. All the DNS record changes (MX, SPF, DKIM, DMARC) are part of the setup. If your domain is managed with us, we make them ourselves and there’s nothing for you to do. If it’s elsewhere, we’ll guide you through it.
This is common. We can audit your existing Microsoft 365 setup and fix misconfigurations across security settings, DNS records, spam filtering, and MFA, to get it working as it should.
