# Microsoft Technologies Supported by US Cloud

Azure fails overnight. Microsoft 365 stops delivering email on Sunday. An Entra ID issue locks employees out at 2 a.m. Enterprise incidents do not wait for business hours—and neither should access to experienced Microsoft support engineers.

One enterprise support approach

## What Microsoft technologies does US Cloud support?

US Cloud provides enterprise Microsoft technical support across major cloud, on-premises and hybrid product families. Our engineers troubleshoot production incidents, help restore services, resolve configuration and performance problems, and coordinate Microsoft escalations where vendor action is required. Use this technology matrix to identify relevant product families and common support scenarios.

Coverage note: This is an illustrative capability map, not a contractual service schedule. Individual features, product versions, legacy products, third-party integrations, proactive engagements and newly released AI workloads should be confirmed in writing during a technical coverage review. “24/7 reactive support” describes the enterprise service model; specific incident routing and severity commitments are defined by contract.

## Microsoft technologies and support coverage matrix

Products are grouped by workload. The listed scenarios show the types of enterprise issues US Cloud can evaluate and address; they do not imply every product feature or integration is included automatically.

Need a product or feature not shown? US Cloud publishes broad coverage of the Microsoft technology stack. Submit your specific product/version inventory for validation rather than assuming an unlisted workload is excluded or automatically covered.

## 24/7 access to Microsoft support engineers—not just ticket intake

Production Microsoft incidents do not follow business hours. US Cloud’s published enterprise support model provides 24/7/365 access to Level 2–3 problem-resolution engineers, with Level 4 engineering for critical incidents. This distinction matters when your business needs experienced troubleshooting overnight, on weekends or across time zones.

##### Always-on reactive support

Open enterprise Microsoft incidents day or night, including critical service outages affecting cloud, hybrid or on-premises workloads.

##### Direct senior expertise

Work with experienced problem-resolution engineers rather than relying solely on a first-level intake and callback model.

##### Managed Microsoft escalations

When a Microsoft product requires vendor-side action, US Cloud coordinates escalation and maintains involvement through the resolution process.

Service-level detail: US Cloud advertises a 15-minute initial response SLA. Confirm the applicable service agreement, severity definitions, credits and exclusions before procurement.

## Enterprise support for cloud, hybrid and on-premises Microsoft environments

Organizations rarely operate just one Microsoft product. An Azure outage may involve Entra identity, virtual networking, SQL databases and on-premises Active Directory; a Teams or Exchange disruption may involve several Microsoft 365 services. US Cloud’s cross-technology support approach helps enterprises investigate incidents that span multiple platforms.

##### Reactive problem resolution

Incident triage, root-cause investigation, configuration troubleshooting and recovery assistance for contracted Microsoft products.

##### Proactive engineering

Architecture reviews, health and performance assessments, migration readiness and designated engineering services when included in the engagement.

##### Unified Support replacement

Independent Microsoft enterprise support that can replace or complement Microsoft Unified Support after workload, escalation and contract validation.

#### How to validate coverage before switching

Provide your Microsoft product inventory, major versions, service dependencies, support ticket history, critical applications, geographic coverage and severity expectations. US Cloud can assess coverage against each workload and document supported services, potential exclusions, engineering responsibilities and escalation processes before transition.
