The post MachPanel v8.3 BUILD 25, Now Available! appeared first on MachSol Blog.

Nobody gets excited about an email server upgrade project. There is no launch event, no ribbon-cutting. And yet, for thousands of service providers and enterprises still running on-premises Microsoft Exchange, the next ten weeks are the most consequential infrastructure window of the decade.

On 31 October 2026, the final Extended Security Update (ESU) period for Exchange Server 2016 and Exchange Server 2019 ends. Microsoft has made clear that this is the final ESU period, with no further extension planned.

If you are still running Exchange 2016 or Exchange 2019 on-premises, this article covers exactly what changed, why the risk is not theoretical, and how to reach Exchange Server Subscription Edition (SE) without turning your migration into a fire drill.

The Timeline, Precisely

A lot of teams are still working from the earlier Exchange 2016 and Exchange 2019 lifecycle calendar. Here is where things actually stand:

For Exchange Server 2016, the distinction between the two support dates matters. October 13, 2020 was the end of mainstream support, while October 14, 2025 was the end of extended support.

Exchange Server 2019 reached the end of mainstream support on January 9, 2024, followed by extended support ending on October 14, 2025.

Period 2 is therefore not a return to normal product support. It is a final security-update bridge for eligible organizations that need additional time to complete their migration.

What Period 2 does not give you

It is worth spelling this out, because the word “support” is doing a lot of misleading work here:

• You cannot open a general support case for Exchange 2016 or 2019. The only exception is a problem caused directly by an ESU update itself.
• No feature requests.
• No performance-tuning assistance.
• No non-security bug fixes.

Treat Period 2 as a temporary security bridge, not a return to normal Exchange support.

Is 31 October 2026 really the final Exchange 2016/2019 deadline?

Yes.

For organizations still running Exchange 2016 or Exchange 2019 on-premises, 31 October 2026 is the date that matters because it marks the end of the final ESU period.

The practical takeaway is simple:

Do not build your Exchange migration strategy around another extension.

Why an Unpatched Exchange Box Is Not a Passive Risk

Exchange sits on the internet edge with administrative reach across your entire mail environment. That combination is precisely why it has a documented, repeated history of becoming the initial access point for ransomware crews and espionage groups.

The ProxyShell lesson. ProxyShell is the name researchers gave to a chain of three flaws — CVE-2021-34473, CVE-2021-34523 and CVE-2021-31207 — discovered by researcher Orange Tsai during Pwn2Own 2021.

CVE-2021-34473 alone carries an NVD severity score of 9.8, and it lets an attacker holding zero credentials exploit the Exchange Client Access Service to gain SYSTEM-level backend access. Chain it with the privilege-escalation and file-write flaws that follow, and an outsider with no account on your network can write a web shell and run arbitrary commands.

CISA added CVE-2021-34473 to its Known Exploited Vulnerabilities catalog in November 2021, and ProxyShell remains an important reminder of what happens when internet-facing Exchange infrastructure falls behind on security updates.

Here is the part that should concern anyone tempted to run past the deadline:

A vulnerability does not become less dangerous simply because it is old.

Legacy Exchange servers do not get safer with age.

They get more thoroughly catalogued.

Your Path Forward: Exchange Server Subscription Edition

Microsoft’s answer for organizations that need to stay on-premises is Exchange Server Subscription Edition (SE) — a shift from the traditional fixed-version model to a subscription-based servicing model.

For organizations searching for an Exchange 2016 replacement, Exchange 2019 replacement, or a supported on-premises Exchange platform, Exchange Server SE is the destination to plan for.

Why SE is the right destination for on-premises Exchange

• Continuous updates. Regular cumulative updates deliver new features, bug fixes and security patches, reducing the need for large, disruptive version-to-version migrations.
• Modern security. Exchange SE incorporates current security capabilities and supported protocols.
• Modern Lifecycle Policy. Exchange SE follows Microsoft’s subscription-based servicing model rather than the traditional fixed-version lifecycle.

The supported Exchange SE upgrade paths

From Exchange Server 2019 → The simplest path is an in-place upgrade to Exchange Server SE. Microsoft supports an in-place upgrade from Exchange 2019 CU14 or CU15.

From Exchange Server 2016 → A legacy upgrade is required. Exchange 2016 cannot simply be upgraded in place to Exchange SE. Microsoft supports a legacy upgrade directly to Exchange SE or a legacy upgrade to Exchange 2019 CU14/CU15 followed by an in-place upgrade to SE.

Still running Exchange 2013? Exchange Server SE does not support coexistence with Exchange Server 2013. Those servers need to be addressed as part of the migration before moving to the supported SE environment.

What is the difference between an Exchange 2016 and Exchange 2019 migration to SE?

Exchange 2019 can follow an in-place upgrade path. Exchange 2016 requires a legacy migration.

That distinction matters when planning an Exchange 2016 to Exchange SE migration versus an Exchange 2019 to Exchange SE upgrade, because the infrastructure, coexistence and mailbox/resource migration requirements are different.

For organizations with a large Exchange estate, this is why migration planning should begin well before the October 2026 deadline.

If you want to understand how MachSol approaches Exchange SE readiness and migration, see our earlier guide on preparing for Exchange Server Subscription Edition.

What This Means Specifically for Service Providers

For an enterprise, this is one migration.

For an MSP, hosting provider or managed service provider running multi-tenant Exchange, it is dozens or hundreds of simultaneous migrations — each with its own mailbox counts, DAG topology, transport rules, branding and billing arrangements.

Sequencing matters more than the deadline itself.

This is where orchestration stops being a nice-to-have.

Manage Exchange Across Multiple Tenants

MachPanel Automation Module for Microsoft Exchange

MachPanel provides a multi-tenant control panel and orchestration platform for hosted Microsoft Exchange, supporting Exchange Server Subscription Edition, Exchange 2019, Exchange 2016 and Exchange 2013 environments. It provides provisioning, management, self-service, monitoring, migration utilities and billing capabilities for Exchange service providers.

Key capabilities include:

• True multi-tenancy with tenant segregation through Microsoft’s Exchange framework.
• Built-in migration tools for importing and migrating existing Exchange environments.
• ADSync integration for directory synchronization and identity management.
• Self-service portals for providers, resellers, customers and AD users.

The post MachPanel v8.1 BUILD 22, Now Available! appeared first on MachSol Blog.

For service providers and enterprises that rely on Microsoft Exchange Server on-premises for their mission-critical email infrastructure, a significant deadline is approaching: October 14, 2025. On this date, both Exchange Server 2016 and Exchange Server 2019 will reach their end of extended support. This isn’t just a calendar event; it’s a critical moment for your organization’s security and stability.

Why This Deadline Matters

End of support means Microsoft will no longer provide security updates, non-security fixes, or technical assistance for these products. Continuing to run an unsupported server is a dangerous gamble. It leaves your system vulnerable to new security threats, bugs, and compliance issues. For a system as central to your operations as Exchange, this is an unacceptable risk.

Think of it like driving a car with a major recall that the manufacturer is no longer fixing. You might get by for a while, but eventually, the issue will catch up to you, and the consequences could be catastrophic. For your business, this could mean a data breach, service downtime, or an inability to meet regulatory compliance standards.

Your Path Forward: The Exchange Server Subscription Edition

Microsoft’s solution for customers who wish to remain on-premises is the Exchange Server Subscription Edition (SE). This new model represents a shift from the traditional one-time purchase to a subscription-based, “evergreen” approach. This means you get a modern, continuously updated product, similar to the experience with Exchange Online, but with the control of your own servers.

Why You Should Upgrade to Exchange Server SE

• Continuous Updates: The most significant benefit of Exchange Server SE is that it receives regular cumulative updates (CUs) that include new features, bug fixes, and security patches. This eliminates the need for large, disruptive upgrades every few years and ensures your system is always up-to-date and secure.
• Enhanced Security: Exchange Server SE includes the latest security features and protocols, like support for TLS 1.3 and modern authentication, which are crucial for protecting your data from an ever-evolving threat landscape.
• Modern Lifecycle Policy: With the subscription model, Exchange Server SE follows Microsoft’s Modern Lifecycle Policy, which provides continuous support as long as your subscription is active. This eliminates the uncertainty of future end-of-support dates.

How to Upgrade: The On-Premises Migration Paths

Microsoft has provided clear, supported paths for upgrading to Exchange Server SE. The migration process depends on your current environment.

• From Exchange Server 2019: The simplest path is an in-place upgrade to Exchange Server SE. This is possible because Exchange Server SE’s codebase is identical to Exchange Server 2019 CU15. However, you must be on Exchange 2019 CU14 or CU15 to perform this seamless upgrade.
• From Exchange Server 2016: For those on Exchange Server 2016, a legacy upgrade is the way to go. This involves introducing new Exchange Server SE servers into your existing organization and migrating mailboxes and other resources to the new environment. Microsoft officially recommends upgrading to Exchange 2016 CU23 before performing a legacy upgrade to Exchange 2019 CU15, which then allows for the in-place upgrade to Exchange SE. However, you can also perform a direct legacy upgrade to Exchange SE.

It’s important to note that Exchange Server SE does not support coexistence with Exchange Server 2013, so any remaining Exchange 2013 servers must be decommissioned first.

Let MachSol’s Professional Services Handle It

The post The Looming Deadline: Exchange Server 2016 and 2019 End of Support appeared first on MachSol Blog.

The landscape of business communication is constantly evolving, and staying ahead means embracing the latest innovations while streamlining operations. This is precisely where MachPanel, the leading multi-tenant control panel for Microsoft Exchange, steps in, now with full support for the Microsoft Exchange Subscription Edition (SE).

The Dynamics of Multi-Tenant Hosted Exchange

For many businesses, the traditional on-premises Exchange server is becoming a relic of the past. The complexities of maintenance, security updates, hardware costs, and the need for specialized IT staff are simply too high. This is why multi-tenant hosted Exchange services have flourished.

What is it? In essence, it’s a model where a service provider hosts a shared Exchange infrastructure, offering email, calendaring, contacts, and collaboration services to multiple distinct organizations (tenants) from a single, robust platform. Each tenant enjoys the benefits of enterprise-grade Exchange features without the capital expenditure or operational burden.

Why is it popular?

• Cost Efficiency: Businesses pay a predictable monthly fee, avoiding large upfront investments.
• Scalability: Easily scale up or down based on organizational needs without hardware concerns.
• Reduced IT Overhead: The service provider handles all the infrastructure, maintenance, and updates.
• Always-On Availability: Professional data centers offer superior uptime and disaster recovery.

However, for service providers, managing such an environment can be incredibly complex. Provisioning new tenants, ensuring strict data segregation, managing diverse client requirements, handling billing, and keeping the underlying Exchange infrastructure up-to-date are monumental tasks. This is where a powerful control panel becomes indispensable.

Embracing the Latest: Microsoft Exchange Subscription Edition (SE)

Microsoft Exchange Subscription Edition (SE) represents the latest evolution in the on-premises Exchange server lineage, designed to provide continuous updates and enhanced capabilities. While it’s a perpetual license model, its features are highly relevant for hosted environments. Exchange SE brings:

• Continuous Updates: Unlike previous versions that required major version upgrades for new features, SE receives ongoing functional updates, ensuring users always have access to the latest improvements.
• Enhanced Security: Robust security features to protect against evolving threats.
• Improved Performance: Optimizations for better user experience and administrative efficiency.
• Modern Management: Aligned with contemporary IT management practices.

For hosted Exchange providers, offering Exchange SE means providing their clients with the most current, secure, and feature-rich email experience, giving them a significant competitive edge.

While limited targeted attacks are being reported on Microsoft Exchange servers, Microsoft is already aware and investigating two reported zero-day vulnerabilities affecting mainly on-premises Microsoft Exchange Servers including Exchange Server 2013, Exchange Server 2016, and Exchange Server 2019. The two vulnerabilities reported are:

• CVE-2022-41040: Server-Side Request Forgery (SSRF) vulnerability
• CVE-2022-41082: Allows Remote Code Execution (RCE) when PowerShell is accessible to the attacker.

Are you already affected with Zero-Day Vulnerabilities in Microsoft Exchange Server?

As a first step you immediately have to verify if you are already affected or not and you can do that through below PowerShell command:

Get-ChildItem -Recurse -Path C:\inetpub\logs\LogFiles -Filter “*.log” | Select-String -Pattern ‘powershell.*autodiscover\.json.*\@.*200’
