I'm using this command New-MailboxExportRequest -Mailbox alias -ContentFilter {(Received -lt "01/05/2011")} -FilePath \\IpAdress\PST\alias.pst where alias is the name of the mailbox. the goal is to archive all the message received before the first of May in a pst file. But the export fails whit this error Request 'RequestGuid (cc5c3cae-5ad1-4b42-8f34-170c4bc0d001), RequestQueue: (ea3cfd74-3555-4378-9c78-6e09f234414f)' (cc5c3cae-5ad1-4b42-8f34-170c4bc0d001) failed. Error code: -2146233088 ContentFilter is invalid. The value "08/01/2010 0.00.00" could not be converted to type System.DateTime. --> The value "08/01/2010 0.00.00" could not be converted to type System.DateTime. Exchange 2010 SP1 ENU on Windows 2008 STD sp2 ENU. My regional settings are italian. Thanks in advance for the help.

try without the " and use ' {(Received -lt '01/05/2011')}Sukh

I try as you suggested New-MailboxExportRequest -Mailbox alias -ContentFilter {(Received -lt '01/05/2011')} -FilePath \\IpAdress\PST\alias.pst but it still doesn' work. Thanks.

New-MailboxExportRequest -Mailbox alias -ContentFilter {(Received -lt '01/05/2011 9:00')} -FilePath\\IpAdress\PST\alias.pstSukh

Nothing to do. I still get the same error. Corto

I found the solution. I set the system language to English (United States) and I ran again the command. The export went well. Thanks for your attention.
