I just run again into this problem too. We got a user request caused by spam mail sent to a shared mailbox. After checking the transport rules and spam filter rules I noticed there is a rule changing SCL to -1 just to prevent emails getting filtered by EOP. We currently put a lot of time and work into things like ATP, MFA and Azure Information Protection and then I see something like this.
So I thought "let's remove this and let EOP do its job so we get rid of this spam in our service mailbox." After digging deeper I saw that users can not access quarantine for shared mailboxes.
How the **** this isn't a feature in Exchange Online?!?!?! We've so many shared mailboxes in our organization and as most companies, we also struggle with spam and phishing and all the stuff. EOP is good but sometimes it just fails and puts false-positive emails into quarantine.
MS users NEED access to the quarantine of shared mailboxes to release emails from it, without having to send a ticket to the user helpdesk for just releasing a mail from the quarantine!
I was shocked to see this request is still open after more than 3 years! MS please add this feature ASAP! It is desperately needed.
