Error Message

There is no error message; it is possible to check if the hidden folder contains items using the Exchange Management Shell command: 

Get-MailboxFolderStatistics mailboxname | where{$_.folderpath -like "*Enterprise Vault - 92746D12-761C-4fe5-9F9B-072F2ABD967A"} | ft alias,folderpath,itemsinfolder

The aforementioned has been observed in scenarios where the registry key DisplayItemsUsingOOM  has a value of 1 and where Microsoft Outlook has multiple Add-ins installed.

As a workaround, disable the DisplayItemUsingOOM by editing the registry key from 1 to 0 on the affected clients.

HKEY_CURRENT_USER\Software\KVS\Enterprise Vault\Client\DisplayItemsUsingOOM to 0 (DWORD)
