FAQ
Do you provide general Microsoft 365 administration?
No. This Gig focuses specifically on Microsoft 365 email security, Defender for Office 365, Exchange Online Protection, secure mail flow, connectors, and related troubleshooting.
Do I need Microsoft Defender for Office 365?
Not necessarily. Exchange Online Protection provides baseline email-security features. Some services such as Safe Links, Safe Attachments, and advanced impersonation protection require appropriate Defender for Office 365 licensing.
Can you troubleshoot Microsoft 365 behind Proofpoint or another email gateway?
Yes. I can review mail-flow, connectors, Exchange Online Protection behavior, authentication handling, and supported third-party gateway integration within the agreed scope.
Can you guarantee that no phishing email will reach users?
No security configuration can guarantee that all malicious messages will be blocked. I focus on identifying configuration gaps, applying appropriate controls, and validating the agreed security changes.
Can you investigate legitimate emails being quarantined?
Yes. I can review message traces, headers, quarantine details, filtering decisions, policies, and related evidence to determine the probable cause.
Do you support Safe Links and Safe Attachments?
Yes, where the Microsoft 365 licensing and tenant configuration support those Defender for Office 365 features.
