How emergency response works
Every emergency call follows a defined triage process. There is no ticket queue — an experienced Exchange engineer joins your call immediately.
- Minute 1–15: Engineer joins remote session. Reviews Exchange event logs, queue viewer, and admin center alerts.
- Minute 15–60: Root cause identified. Workaround or fix applied. Mail flow restored or mitigated.
- Hour 1–4: Full resolution confirmed. Connectors, databases, and security validated.
- Within 24 hours: Written incident summary and permanent fix recommendation delivered.
Common emergency scenarios
Mail flow stopped
The most common Exchange emergency. Root causes include a broken send connector, expired TLS certificate, blocked relay, or DNS MX record issue. EPC Group diagnoses and restores mail flow — typically within 60 minutes for standard scenarios.
Database corruption
Exchange database corruption requires immediate action. A database in a failed mount state prevents mailbox access for affected users. EPC Group runs ESEUtil checks, repairs soft corruption, and restores from backup if hard corruption is confirmed.
Compromised mailbox
A compromised Exchange mailbox can become a spam relay within minutes. EPC Group resets credentials, revokes active sessions, blocks outbound spam relay rules, and reviews inbox rules for persistence mechanisms left by the attacker.
Frequently asked questions
How fast does EPC Group respond to Exchange emergencies?
Our target response time is 15 minutes. An Exchange engineer joins your remote session without routing through a support ticket queue. For critical emergencies — mail down, database corrupted, security breach — call (888) 381-9725 directly.
Do you support on-premises Exchange and Exchange Online?
Yes. EPC Group provides emergency support for all on-premises Exchange Server versions and Exchange Online. For hybrid environments, we support both sides of the hybrid connection simultaneously.
What qualifies as an Exchange emergency?
Critical emergencies include: all mail flow stopped, Exchange database failing to mount (users locked out of mailboxes), security breach (compromised mailbox, spam relay), expired certificate blocking OWA or hybrid, and DAG failover failure leaving databases without redundancy.
Can you fix Exchange issues remotely?
Yes. Nearly all Exchange emergencies are resolved remotely. EPC Group engineers access Exchange Admin Center, Exchange Management Shell, and your environment via a secure remote session. On-site work is rarely needed for Exchange incidents.
