I am currently trying to configure granular Exchange 2013 mailbox permissions for a new mailbox I created. I am using Exchange PowerShell to do so. When granting a user ReadPermission via the command Add-MailboxPermission, I am able to see that the user is then given ReadPermission, however, when trying to add the mailbox in Outlook (2010), it is saying that the folder can not be displayed. I can only display/open the folder and subfolders when granting FullAccess.
I would like to assign Read Only permissions to this folder for certain users. I am not sure how to do this since when assigning ReadPermission to the mailbox it does not allow me to even open the mailbox once adding to Outlook.
