I want to configure a shared mailbox on Exchange 2016 on premise server with folder assigned permissions.
Shared mailbox name
3 users Bob, Mike, Steve
3 folders in shared mailbox with same names as users.
Each user will need full right to folder with their name and view only rights to other folders.
I can assign right via PowerShell command below
MY problem is that if I do delegate shared mailbox with users Bob, Steve and Mike they will have full rights to all folders regardless of folder permission assign
While if I don’t use any delegation and only configure folder permissions none of the users can mount shared mailbox and see the folders.
[PS] C:\Windows\system32>Get-MailboxFolderPermission\bob

FolderName           User                 AccessRights
----------           ----                 ------------
Bob                 Default              {None}
Bob                 Anonymous            {None}
Bob               Mike            {Reviewer}

When user Mike try to open shard mailbox
Access denied with error below
Something went wrong
You don't have permission to open this mailbox.

How can I give access to shared mailbox to uses without giving them delated right?
I am only looking for a true expert advice who has hands on experience with same problem.
