By default “Recoverable deleted items folder” Should not show up in Outlook or OWA
But if we would have done a PST migration with include dumpster switch .
While importing the pst the import request folder would treat recoverable items folder as a normal folder and not as hidden folder.
As it will display to users and starts the confusion.
as shown in the below image
How to make it hidden without breaking anything . or the restore feature.
Get a test machine
Open Outlook – Create a profile for the problematic user
Session – Logon
Choose the problematic profile
Double Click on the first folder – Which will open up the skeleton of the mailbox
Expand – IPM_SUBTREE
Go to “Recoverable Items”
See on the right Side you can see “PR_ATTR_HIDDEN”
Right click on the attribute – Edit property
Check “Boolean” – Click ok

Now it should not be visible to the user
