I am running Exchange 2007, with most clients using OWA and a few hundred using Outlook 2003-2007. Mail is stored on the Mailbox servers and the users do not have PST's. I have several users who are now trying to create Archive.PST's and PST's. They cannot move single messages or multiple messages to any Archive or additional PST. These users are spanned on several databases/storage groups. They receive the following message when trying to move messages into a PST/Archive: "The Item Cannot Be Moved. It was either already moved or deleted, or access was denied". I have followed all of the suggestions on this site and nothing works. The PST's or Archives are newely created, have been recreated and placed locally where they have full permission. Users can move messages freely if they do so in the mailbox, but once it is going to a local PST/Archive, I receive that error message. PLEASE HELP!
