Does anyone know how to remove .wav files from Exchange 2007 message stores?

Hi Tuye, You could use command export-mailbox to export and delete all mails with wav extension attachment in the database. Get-mailbox -database 'DB1' | export-mailbox –AttachmentFilenames "*.wav" -TargetFolder "WavAttachmentData" -TargetMailbox Administrator –DeleteContent Related articles: http://technet.microsoft.com/en-us/library/aa998579.aspx http://msexchangeteam.com/archive/2006/11/28/431669.aspx Thanks, Elvis
