Microsoft Premier & Unified Support — Escalation & Resolution Liaison

Microsoft Premier Support assistance from IT Partner helps organizations with complex Microsoft 365 issues that exceed standard troubleshooting. Microsoft has retired Premier Support for new contracts — Microsoft Unified Support is its successor — so IT Partner assesses each issue, gathers the required technical evidence, escalates through the Microsoft support channel available to your organization (a still-active legacy Premier agreement, Microsoft Unified Support, or partner support channels), and collaborates on implementing and verifying recommended solutions.

01 — Overview

What this engagement is

This service helps your organization escalate complex Microsoft 365 issues to Microsoft's advanced support organization when standard troubleshooting is not sufficient. Microsoft Premier Support is a legacy program: Microsoft stopped selling new commercial Premier contracts on July 1, 2021, ended commercial renewals on July 1, 2022, and ended public-sector renewals on July 1, 2024, with Microsoft Unified Support as the successor for enterprise support agreements. IT Partner assesses the issue, collects relevant technical details, coordinates communication with the Microsoft support channel available to your organization — an existing Premier agreement where one is still active, Microsoft Unified Support, or Microsoft support through partner channels — and helps implement and verify recommended solutions. IT Partner can also help you evaluate Microsoft Unified Support or use IT Partner's own support services as an alternative for many scenarios.

✕24/7 support, 24x7 incident bridge coverage, after-hours support, continuous crisis management, continuous monitoring, and ongoing maintenance are not included by default.

✕Remediation of unrelated configuration issues discovered during troubleshooting unless separately scoped.
✕Support for non-Microsoft platforms, custom applications, third-party integrations, network providers, identity providers, or on-premises infrastructure except where directly required to provide evidence for the Microsoft escalation.
✕Custom development, advanced scripting, automation buildout, or code-level debugging outside standard diagnostic and remediation activities.
✕Security incident response, forensic investigation, eDiscovery, legal review, or compliance investigation unless separately contracted.

08 — Fine print

Limitations & technical notes

!The listed service period is 30 days, but final resolution may take longer depending on issue complexity, Microsoft Support engagement, log availability, reproduction steps, and required customer approvals.
!Not every issue will qualify for escalation; IT Partner first assesses whether escalation is appropriate and whether sufficient evidence is available.
!Microsoft may request additional diagnostics, traces, tenant data, reproduction sessions, or configuration changes before providing a final recommendation.
!Some Microsoft 365 and Office 365 changes require propagation time and may not show immediate results after remediation.
!Recommended fixes may require a maintenance window, user testing, service configuration changes, or temporary business impact, subject to customer approval.
!Troubleshooting can be constrained by limited administrative access, incomplete logs, privacy restrictions, third-party dependencies, or unavailable affected users.
!IT Partner coordinates and collaborates on Microsoft Support recommendations, but Microsoft-controlled service-side actions and timelines remain dependent on Microsoft. Escalation paths depend on the support entitlements available to your organization: Microsoft no longer sells or renews Premier Support contracts, and Microsoft Unified Support is the successor program.
09 — Questions

Frequently asked questions

What is Microsoft Premier Support from IT Partner?

It is an escalation-assistance service for complex Microsoft 365 issues that exceed standard troubleshooting. IT Partner assesses the issue, gathers the technical evidence Microsoft needs, coordinates escalation through the Microsoft support channel available to your organization — a still-active legacy Premier agreement, Microsoft Unified Support, or partner support channels — and helps implement and verify recommended solutions.

Is Microsoft Premier Support still available from Microsoft?

Not for new contracts. Microsoft stopped selling new commercial Premier Support agreements on July 1, 2021, ended commercial renewals on July 1, 2022, and ended public-sector renewals on July 1, 2024 (some existing public-sector contracts run into 2027). Microsoft Unified Support is the successor program. IT Partner helps you escalate through whichever channel your organization has, evaluate Microsoft Unified Support, or cover many scenarios with IT Partner's own support services.

When should we use this Microsoft Premier Support service?

Use this service when a Microsoft 365 issue is too complex or critical to resolve through standard troubleshooting. IT Partner first assesses the situation, because not every issue requires — or qualifies for — escalation to Microsoft.

What is included in the service?

The service includes issue assessment, collection of relevant technical information, escalation to Microsoft Support when required, liaison support between your organization and Microsoft, and collaboration on recommended fixes. IT Partner also helps verify whether the implemented solution is effective.

What information will IT Partner collect before escalation?

IT Partner gathers relevant troubleshooting information such as error messages, logs, and system configurations, because Microsoft Support can troubleshoot more efficiently when the escalation includes complete technical context.

Does IT Partner automatically escalate every case to Microsoft Premier Support?

No, escalation is based on an initial assessment of the issue. IT Partner determines whether the problem requires Microsoft Support involvement, because some issues can be addressed through standard troubleshooting or need more information before escalation.

How long does the Microsoft Premier Support engagement take?

The service period is 30 days. Actual time to final resolution depends on the complexity of the issue, the completeness of logs and access provided, and Microsoft's troubleshooting process.

How much does the service cost?

Pricing is quoted per engagement — contact IT Partner for a quote. The quote is provided in writing before work begins.

Which Microsoft products does this service cover?

This service is listed for Office 365 and Microsoft 365 environments. If your issue involves another Microsoft product or a hybrid dependency, confirm applicability with IT Partner before assuming it is in scope.

What are the client’s responsibilities during the engagement?

The client must promptly notify IT Partner of complex issues, provide necessary access permissions, log files, and relevant information, and stay engaged by responding to requests for additional data or testing. This participation is important because escalation and validation depend on timely access to the affected environment and evidence.

What is not included in this Microsoft Premier Support service?

By default, this service does not include guaranteed resolution, guaranteed Microsoft response times, large-scale remediation, unrelated configuration remediation, long-term managed operations, recurring health checks, or post-resolution optimization. 24/7 support, continuous monitoring, and ongoing maintenance are available as optional extra-cost add-ons delivered through IT Partner's NOC, third-party support partnerships, and Microsoft support escalation channels. Anything beyond assessment, information gathering, escalation coordination, liaison support, solution collaboration, and verification should be confirmed with IT Partner before work begins.

Is a successful resolution guaranteed?

The service aims for swift resolution, access to Microsoft expertise, clear communication, and improved operational continuity. However, the stated scope does not provide a guaranteed resolution or fixed Microsoft response time, so expectations should be confirmed with IT Partner for the specific incident.
