Accessing the quarantine of a shared mailbox

Occasional Contributor

I found a few articles that indicate a user should be able access the quarantine of a shared mailbox if they are given full access to the mailbox.  It appears the user must be given access using their active directory account -- not through a group.


We have tried this on a few shared mailboxes and get the same result. When we click on a "review" link in the quarantine email, we receive this error:


The operation couldn't be performed because the user does not have the authorization
Any suggestions or things to check?  Thank you!

You should be able to use the Filter control in the UI to achieve that, but a fellow MVP reported some issues with this functionality. Adding @Arindam Thokder as he might be able to share more details.

@JG-Burke - one can open quarantine of shared mailbox from clicking on the link on the End user spam notification which would be delivered to the shared mailbox. There is also another easy way where a mailbox with full permission can open their own Quarantine and then from the filter, change the recipient address and and mention the shared mailbox there. However this has some issue now which are looking at this moment. It should start working very soon.

I can not confirm that the access works. Neither on the one way, nor on the other.
When the user (with full access to the shared mailbox) clicks on review in the notification, the (empty) quarantine opens and a message appears that there is no authorization. Also the search does not work, because the quarantine is empty.

Somehow only the quarantine of the user and not the one of the shared mailbox is displayed. (Username is in the upper right corner)

Is there anything left to set?
Hopefully someone will find a solution for this soon.

Same here. I'm even able to reproduce that myself. Already tried removing and re-adding full access to the mailbox (directly, not via synced AD group).

I guess Microsoft needs to be made aware of this.
@Piotr_Jezewski @lazarus72 - As mentioned earlier, the plan is to give end user access the quarantine for shared mailbox by changing the recipient address to shared mailbox from quarantine portal. This change is yet to be enabled for worldwide tenants. Unfortunately, I do not have an ETA for this.
