To let users only review emails but unable to edit/remove emails in shared mailbox, you can setup the shared mailbox by following the steps below,

1 - Remove the user from the group which has been granted the full access permission on the shared mailbox,
2 - Open the shared mailbox in Outlook with another account who has full access permission on the shared mailbox,
3 - Right click the shared mailbox, click Data File Properties, in Permission tab, click add to add a user, and choose reviewer from the Permission level drop down list,
4 - Right click the inbox folder of the shared mailbox, click Properties, in Permission tab, click add to add the same user, and choose reviewer from the Permission level drop down list,



Then this user can open the shared mailbox in Outlook as usual but only able to view the emails in inbox and unable to edit/remove emails.
