​
Monitoring & Reputation

TenantCore continues monitoring infrastructure after domains and mailboxes are created. The goal is not just to tell you whether a resource exists. TenantCore also tracks signals that can show when an outbound environment is degrading.

​
Infrastructure monitoring

TenantCore can monitor or surface conditions such as:
  • tenant access
  • Microsoft licence state
  • application permission health
  • DNS readiness
  • sending IP or location
  • mailbox usage
  • sending-platform connection state
These are operational signals. They tell you whether the infrastructure is configured and reachable as expected.

​
Reputation monitoring

Reputation monitoring looks at sending outcomes rather than only configuration. Important signals include:
  • hard bounces
  • outbound spam-related verdicts
  • Microsoft restriction state where available
  • sending counts and utilization
These signals can be evaluated at mailbox, domain, and tenant level.

​
Volume is not reputation

A mailbox can stay under its configured send limit and still have poor reputation. For example:
Send limits control volume. Reputation monitoring evaluates what happens to the messages being sent.

​
Authentication is not reputation

Healthy SPF, DKIM, and DMARC are important, but they do not guarantee good sending reputation. A correctly authenticated message can still be unwanted mail. TenantCore therefore treats DNS/authentication health and reputation as related but separate parts of infrastructure health.

​
BYOT vs. managed enforcement

Reputation visibility is useful across TenantCore plans. The enforcement boundary is different depending on infrastructure ownership.

​
BYOT tenants

TenantCore can provide:
  • monitoring
  • Reports
  • alerts
  • notifications
  • reputation and risk visibility
For customer-owned Microsoft 365 tenants, TenantCore does not automatically make reputation-remediation changes to Exchange. The operator remains in control of that infrastructure.

​
TenantCore-managed infrastructure

When TenantCore-managed infrastructure becomes available, managed environments may support automatic remediation under TenantCore’s managed-infrastructure policy. That distinction is based on who manages the infrastructure, not on the customer’s plan tier.

​
Reports

Reputation data feeds the broader Reports experience. This lets the operator review:
  • current state
  • historical incidents
  • resource-specific activity
  • measured counts and rates
  • related TenantCore actions
Monitoring tells you what is happening now. Reports help explain what happened over time.
