Delete EV ShortCuts Exchange Mailbox

Hello all,

I'm trying to delete or view the result of EV Shortcuts in a user mailbox with the follwowing commands:

Search-Mailbox -Identity UserName -SearchQuery "IPM.NOTE.EnterpriseVault.Shortcut" -DeleteContent

or

Search-Mailbox -Identity UserName -SearchQuery "IPM.NOTE.EnterpriseVault.Shortcut" --EstimateResultOnly

With Enterprise Vault 9.0.1.1073 and Exchange 2010 sp3 those commands works fine to delete or show the result for all the EV shortcuts in a mailbox. If I'm

executing this commands on an environment with Enterprise Vault 11.01 and Exchange Server 2013 CU8 the output is: ResultItemsCount: 0 even if there are

thousands of ev shorcuts in the mailbox.  

Thank you all in advance, any information would be very helpful.

Regards,

Tom
