US Based Exchange Server Support, in America, by Americans
Is your Exchange server down? Call +1 (210) 497-1424 now. Nationwide remote support and disaster recovery for on-premises Microsoft® Exchange Server, every version from 2003 through Exchange Server Subscription Edition (SE), handled by engineers who run Exchange for a living.
Our lead Exchange engineer supports enterprise on-premises Exchange environments daily. Database Availability Groups, compliance holds, audited change control, environments where mail simply cannot go down. That is the level of discipline your server gets, whether you run 5 mailboxes or 5,000.
Emergency Exchange Server Support and Disaster Recovery
When Exchange breaks, the whole business feels it in minutes. We handle the failures that take mail down:
- Server down, databases won’t mount, dirty shutdown states and log replay recovery
- Database corruption, ESEUTIL repair decisions, and recovery database restores
- DAG failures, failed-over copies that will not reseed, quorum and witness problems
- Mail flow stopped: queues backing up, transport failures, connector misconfiguration
- Certificate expirations breaking Outlook, OWA, ActiveSync, and hybrid mail flow
- Autodiscover failures, broken virtual directories, and client connectivity problems
- Hybrid failures: broken directory sync, Entra Connect errors, and mail stuck between on-premises and Exchange Online
- Blacklisted IPs, spoofing incidents, SPF, DKIM, and DMARC cleanup
- Disk full conditions, transaction log runaway, and backup failures that stopped log truncation
Remote-first for speed, nationwide. A free consultation is available, and project or remediation timelines are provided before work begins. When a server failure takes the whole office offline locally, our network outage repair crew responds the same day across San Antonio.
Every Exchange Version, Including the Ones Everyone Else Abandoned
Microsoft support has ended for every on-premises Exchange version except Exchange Server SE. That does not make your server disappear, it makes it an orphan, and most IT companies will not touch it. We support them all:
- Exchange Server SE (Subscription Edition), the current and only Microsoft-supported on-premises version
- Exchange 2019 and 2016, out of extended support since October 2025, still running in thousands of businesses
- Exchange 2013, end of life since April 2023
- Exchange 2010, 2007, and 2003, the legacy servers nobody else will answer the phone for
Running an out-of-support Exchange server is a real risk: no security patches, and Exchange is one of the most actively attacked products on the internet. We will keep an aging server alive when business reality requires it, stabilized, hardened, and backed up, and we will tell you honestly when it is time to move.
Exchange Server End of Support (EOS): 2016 and 2019 Are Past the Deadline
Microsoft ended support for Exchange Server 2016 and Exchange Server 2019 on October 14, 2025. If you are still running either one, you are past EOS right now: no security updates, no bug fixes, no Microsoft support ticket to open. That is exactly the moment businesses start searching for an Exchange Server EOS support provider, and it is work we have been doing for decades, because we never abandoned the old versions in the first place.
You have three honest paths, and we support all of them. Upgrade on-premises to Exchange Server SE, the subscription edition that replaced 2019, with us as your Microsoft Exchange migration partner handling the move mailbox by mailbox. Migrate to Exchange Online and Microsoft 365 if the cloud finally makes sense for you. Or buy yourself a supported runway: our managed IT services for Microsoft Exchange on-premises keep your legacy server patched where possible, monitored, backed up, and running safely behind a properly configured firewall while you decide on your own schedule instead of Microsoft’s.
And if you have been searching for a Microsoft Tier 3 support alternative because Microsoft’s own queue no longer answers for your version, that is us in practice: senior Exchange engineers, direct on the phone, without the enterprise support contract.
Exchange Migrations: On-Premises, Cloud, or Hybrid
Three honest paths off an unsupported version, and we do all three:
- Stay on-premises: migrate to Exchange Server SE. For organizations with data sovereignty, regulatory, or cost reasons to keep mail in-house. We plan and execute the upgrade path from your current version, including the multi-hop migrations older versions require. We supply, configure, and sell the on-site server hardware and licensing for the upgrade, one vendor for the whole stack.
- Move to the cloud: migrate to Microsoft 365 / Exchange Online. Cutover, staged, or hybrid migrations with mail flow, Autodiscover, and mobile devices handled, so the office comes in Monday and mail just works.
- Run hybrid: on-premises Exchange synchronized with the cloud. Some mailboxes on your server, some in Exchange Online, one shared address book, unified mail flow, and free/busy calendaring across both. Hybrid is the right answer for staged moves, compliance workloads that must stay local while everything else goes to the cloud, and organizations that want cloud resilience without giving up the on-premises server. We build, fix, and manage Exchange hybrid configurations, including Entra Connect directory synchronization, hybrid mail flow, and the certificate and Autodiscover plumbing that makes coexistence seamless.
Already mid-migration and stuck? We also support migration efforts in flight: stalled mailbox moves, hybrid configuration wizard failures, directory sync errors, mail flow broken between on-premises and the cloud, and projects a previous vendor abandoned halfway. We will pick it up, assess where it actually stands, and land it.
We will give you a straight recommendation based on your compliance requirements, budget, and appetite for server ownership, not on what pays us the most.
Ongoing Exchange Server Management
Beyond emergencies, we provide ongoing management for on-premises Exchange: cumulative updates and security patching, backup verification and restore testing, storage and database health, certificate lifecycle, spam and mail hygiene, and monitoring that catches transaction log growth before it fills a drive at 2 AM. If an aging Exchange server is just one of many IT fires you’re fighting, our San Antonio IT support team can take over day-to-day management.
Why Businesses Still Run On-Premises Exchange
The cloud is not the answer for everyone, and we will not pretend it is. On-premises Exchange still makes sense for organizations with data sovereignty and regulatory requirements, environments with limited or unreliable internet, businesses that want predictable costs instead of per-mailbox subscriptions forever, and shops with existing server investments that still have life in them. High availability without expensive SAN storage has been built in since Database Availability Groups arrived in Exchange 2010, and the standard license covers what most small and mid-size businesses need. Enterprise licensing adds in-place archives, legal holds, and the compliance features regulated industries require. Auto-configuration, Outlook Anywhere, and Outlook Web Access mean any device can reach an Exchange mailbox, on-prem or not.
Exchange Server Support FAQ
My Exchange version is out of Microsoft support. Can you still help?
Yes. Supporting out-of-support Exchange is a specialty of ours, including 2003, 2007, 2010, 2013, 2016, and 2019. We stabilize, harden, and back up aging servers, and we plan the migration for when you are ready.
What does Exchange Server end of support (EOS) mean for us?
EOS means Microsoft stopped issuing security updates, fixes, and support for your version. Exchange 2016 and 2019 both reached end of support on October 14, 2025. Your server keeps running, but every month unpatched increases risk. Your options are upgrading to Exchange Server SE, migrating to Microsoft 365, or having a provider like ASAP manage and harden the legacy server while you plan the move.
Exchange is down right now. What do I do?
Call +1 (210) 497-1424. Do not run repair utilities or reboot repeatedly before talking to an engineer, some recovery paths close permanently if the wrong step runs first. We will triage remotely and give you a straight assessment of the fastest path back to mail flow.
Should we upgrade to Exchange Server SE or move to Microsoft 365?
It depends on your compliance requirements, internet reliability, and cost tolerance. SE keeps mail in-house under your control with subscription licensing; Microsoft 365 trades control for reduced server ownership. We do both and will recommend based on your situation, not our margin.
Can you set up or fix a hybrid Exchange environment?
Yes. We build and repair hybrid configurations: on-premises Exchange synchronized with Microsoft 365, including Entra Connect directory sync, hybrid mail flow, shared calendaring, and staged mailbox moves in either direction. We also rescue hybrid setups and migrations that a previous vendor left half-finished.
Can you support us remotely if we are not in Texas?
Yes. Exchange support and disaster recovery are delivered remotely nationwide, and have been for years. On-site work is available in the San Antonio region.
Do you provide hardware and licensing too?
Yes. We sell, configure, and install on-site server hardware for Exchange upgrades, along with Exchange licensing and implementation. Colocation and ongoing management are also available if you want Exchange expertise without building it in-house.
