I am running Windows XP and Outlook 2003 I seem to have completely messed up my folders and accounts. In ''all mail folders'' i have the remnants of 1 named accountand one personal folders account. The main Personal folders file still resides at the top of the list. However just merely clicking on the file name brings up an error message ''the set of folders could not be opened'' I might have accidentally deleted the pst files and now i am stuck. I have tried reloading and deleting 2003 but the problem persisists. Has anyone got any idea how i might rectify this problem. I have 100s of mails in my main personal folders file that i dare not lose!
