Six Exchange disciplines, one operational team.
Mailbox lifecycle
Provisioning, deprovisioning, archiving, retention, litigation hold. Joiner-mover-leaver workflows automated through Entra ID + Exchange policies.
Anti-phishing & anti-spam
Exchange Online Protection (EOP) baseline plus Defender for Office 365 advanced filtering. Tuned for your email patterns, false-positives suppressed.
DKIM, SPF, DMARC
Email authentication standards configured per domain. DMARC reporting analysed weekly, drift detected and remediated before mail-flow disruption.
Calendar & resource management
Room mailboxes, equipment mailboxes, shared mailboxes. Calendar permission discipline, delegate management, EWS-aware integrations.
Hybrid configurations
Hybrid Exchange (cloud + on-prem) for migrations or compliance. Stub-and-archive, journal-based archiving, regulatory mail retention.
Mail flow visibility
Mail-flow reports, message-trace analysis, bounce-back diagnostics, transport-rule auditing. Mail-flow incidents triaged in minutes.
Four reasons clients pick us for the management.
500+ Exchange tenants
Pattern recognition matters. We have run Exchange across SMEs, financial services, healthcare, and education. Common mail-flow issues, common filter quirks.
Mail-flow incidents in minutes
Mail-flow incidents (mass NDRs, blocking, blacklisting) get same-hour response. Our SOC monitors EOP and Defender alerts continuously.
Hybrid expertise
Cloud-only, hybrid, and pure on-prem Exchange engagements. Migration work routine; many clients arrive on Exchange 2013/2016/2019 needing modernisation.
US-based engineers
Senior Exchange engineers based in the United States. Same time zone as your help desk, same business context as your stakeholders.
Exchange engagements by sector.

Financial services
SEC- and NYDFS-regulated firms with regulator-mandated mail retention, journal-based archive, audit-trail mail flow, signed/encrypted external communications.
Healthcare
Hospitals, clinics, medical groups with PHI-aware mail filtering, patient-record-system integration, HIPAA-compliant retention.
Tech and SaaS
SaaS companies with high-volume transactional mail (alerts, customer notifications), DKIM/SPF/DMARC discipline, custom transport rules.
Retail and operations
Retail groups with multi-store mail flow, supplier-comms templates, customer-service mailboxes, transport-rule routing for support escalation.

“We had Exchange 2016 on-prem and the upgrade kept getting deferred for budget reasons. GR IT planned a phased migration to Exchange Online, ran the cutover over three weekends across our 220 mailboxes, and we have not had a mail-flow issue since. Spam volume dropped 80%, our regulator-required journal archive is finally working, and we no longer maintain Exchange servers.”
