AWS User Notification De-duplication not working

I may related to:

• Aggregated notifications in the management account • Individual notifications for each member account because: o The contacts are not shared across accounts o Deduplication only suppresses email delivery, not console notifications o You may have subscriptions set up per account, not just centrally

Hi Chad, is the duplication on email only or are you also seeing the 4 notifications (1 aggregate and 3 duplicates) in the management account's notification center under the "AWS managed" tab?

If you're able to, please open a support case with the above information and provide us with your account IDs.

Thank you for the response Kidd Ip and the review Jordan Sandri!

• Aggregated notifications in the management account

I'm not sure what this means. I am getting aggregated notifications AND the individual notifications. I'm trying to figure out how I can just get the aggregated.

• Individual notifications for each member account because:

I do see the notifications in the root account's AWS Health screen, so I think they are getting all the way up to the root account. And I've turned off all subscriptions in all member accounts.

o The contacts are not shared across accounts

I have made sure that the billing, operations, and security contacts are exactly the same across all accounts including the root.

o Deduplication only suppresses email delivery, not console notifications

I'm getting duplicate emails (the aggregate and also the individuals)

o You may have subscriptions set up per account, not just centrally

I disabled AWS User Notification subscriptions across all accounts except the root/management account.
