Good day community,

Does the Attack Simulation capabilities extend to on-prem/hybrid Exchange environments as well, or only accounts that have been migrated fully to Exchange Online?

TIA

Hey Sebastiaan, Thanks for your query. We do support delivery to on-prem mailboxes however, please note that for these accounts there will be limited functionality. While core features will work fine, the reported email (reported phish) telemetry will not be available for on-prem accounts.

Thanks,
Gopal

@Gopal-MSFT can you elaborate on what exactly what isn't supported with on-premise mailboxes.  There are no limitations I can find on the Microsoft documentation https://learn.microsoft.com/en-us/microsoft-365/security/office-365-security/attack-simulation-train... or the FAQ https://learn.microsoft.com/en-us/microsoft-365/security/office-365-security/attack-simulation-train...
