To free up space on my system partition, I recently moved all of the files and folders under "My Documents" to another partition on the same drive. This I did according to the instructions from Microsoft. I keep my Outlook PST files in a folder inside My Documents called Outlook Files. After the move, when I started up Outlook 2010 Beta I was told that the PST files could not be found and was asked to direct the program to their location and then close and reopen Outlook. I did this and when I reopened the program, all my emails, including subfolders, sent mail, contacts, etc., were there. However, now when I try to send/receive I get both send and receive errors, and the error dialog box contains the phrase "Outlook Data File cannot be accessed". Since obviously the program *is* accessing these data files, at least for read purposes, and since I checked and these files' attributes are set to permit both read and write/modify, I am flummoxed. Ideas?
