I'm stumped. I've got a user with Outlook 2003. His calendar has over 160mb of data, because he attaches relevent docs to each meeting request. The problem is that his calendar is taking up over 1/2 of his alloted mail space. I setup a new PST, went into FILE - ARCHIVE, picked the THIS FOLDER AND ALL SUBFOLDERS, selected the CALENDAR folder, and ARCHIVE EVEN IF DO NOT ARCHIVE.. options. I set the date to 1/1/2008. I clicked the OK button, and Outlook showed "Archiving..." at the bottom of the window. However: the PST file remains empty. I've tried multiple times with no luck. I've gone as far as removing and re-creating his Outlook profile, including a fresh OST file, and tried it with Cached mode on and off. I even ran a full reinstall of Office 2003 sp2. Anyone have any thoughts?
