MICROSOFT 365 & BUSINESS EMAIL
Email that works for your business—and helps protect your reputation.
We help small businesses configure, secure, migrate, and manage Microsoft 365 and business email, from everyday user support to the DNS records that help keep legitimate messages out of spam.
Business email that works the way it should.
Microsoft 365 • Security • Deliverability • Authentication • Monitoring
More than a mailbox.
Business email touches communication, identity, security, compliance, and your company’s reputation. Green Street helps manage the pieces together instead of treating email as something that ends once a mailbox is created.
Microsoft 365
Setup, licensing, migrations, mailbox configuration, shared mailboxes, aliases, and ongoing administration.
Email Security
Spam and phishing protection, safer account configuration, security policies, and controls designed to reduce email-based risk.
Email Deliverability
Configuration that helps receiving systems verify your mail and improves the chances legitimate business email reaches the inbox.
Authentication Monitoring
Review authentication results and domain configuration so problems and unauthorized sending sources can be identified.
User & Account Management
New users, departures, access changes, mailbox permissions, multi-factor authentication, and practical account administration.
Signatures & Standards
Consistent business signatures and sensible email standards that help your company communicate professionally across devices.
How secure is your email domain?
Use our free domain security tools to check SPF, DKIM and DMARC — and learn how Green Street can help correct and monitor your email authentication.
SPF, DKIM and DMARC should not be “set it and forget it.”
These records work together to help receiving mail systems determine whether a message claiming to come from your domain is legitimate. Poor configuration can hurt deliverability; missing protection can make domain spoofing easier.
We help configure authentication around your actual mail sources and maintain it as services change.
- Review and configure SPF records
- Enable and validate DKIM signing
- Implement DMARC with an appropriate policy
- Review DMARC reporting and authentication failures
- Identify legitimate and unexpected sending sources
- Update records when vendors or email platforms change
Good email security is a combination of technology and good practice.
Authentication is important, but it is only one layer. We help small businesses build a more complete email setup around the way their people actually communicate.
Security best practices
Multi-factor authentication, appropriate administrative access, strong account recovery practices, phishing and spam protection, user lifecycle management, and regular review of suspicious activity all contribute to a safer email environment.
Ongoing management
Email systems change. Employees come and go, vendors begin sending on your behalf, DNS records are modified, and security threats evolve. Ongoing administration and monitoring help prevent yesterday’s correct configuration from becoming tomorrow’s problem.
