We're experiencing an issue where users are reporting emails as "not junk" or "not phishing", but they receive a Non-Delivery Report (NDR) indicating that one of the Global Administrator accounts involved doesn't have an Exchange license. I'm confused about why this specific account is receiving the reports, especially since I've found that the alert policy for "Email reported by user as not junk" targets tenant admins. Is there a reason only this unlicensed account is getting these notifications? Do we need to keep this alert policy, or should I just disable the notifications altogether? We're currently on the default alert policy settings.

It seems like Microsoft expects admins to have licenses for everything they manage, even though it's not strictly enforced for all services. This could definitely cause the problems you're seeing with reports. One way around this is to change the default alert policy or set up a mail rule in Exchange Online to capture these notifications instead of letting them bounce to unlicensed accounts.

Should I just turn the notifications off? Also, do you have any idea why just one Global Admin account is causing issues while others aren't?
