First : Data was restored to RDB with DPM 2010. I can use command New-MailboxExportRequest, to get data exported to PST, and it has all filtered data, that I`m trying to test with command Restore-Mailbox. So I'm putting up a simple challenge : is TechNet Article :http://technet.microsoft.com/en-us/library/bb125218.aspxcorrect or it is missing fine print. Because filers Subject Keywords, SenderKeywords, AllContentKeywords, ContentKeywords do not work. It might work before SP1, I did not try it, but I'm not planning to do. I use Exchange 2010 SP1 RU3v2. The reason Why I asking these question is, that I`m designing DR procedures for Exchange organization, and I do not know how to explain customer that article about Restore-Mailbox command is wrong, except that I open case at Microsoft and ask them about a problem, that i7m having. I have put to questions, which are unanswered: http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/e0cc4967-681f-49bd-8ce7-578cba2c3986/ http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/ca2db964-680d-4f17-b650-0609feb897a0

You'll probably get a better response to your questions if you put all relevant information in your post and don't ask us to chase a bunch of links. One piece of valuable information you didn't provide is the exact and complete Exchange Management Shell command you are issuing and the exact and complete error message you receive, if any.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

Simple response : Information about command restore-mailbox, at the following link IS WRONG : http://technet.microsoft.com/en-us/library/bb125218.aspx Switches : SubjectKeywords , SenderKeywords , RecipientKeywords simple do not work under SP1.
