Hello everyone I guess this is not a very new topic, but after 7 hours of reading trough the web, and at 2am. this is kind of my last hope to get this sorted! I'm having a 3.7 GByte pst file, which I've used with no problem in my Windows 7 professional and Outlook 2010 (32bit). So then when I tried to set up a new account (POP3), I realized, that new emails sent and received would not be stored in the same PST file and I thought I need to just better configure. Because I haven't been able to clone my Harddrive I've just made copies of my 2 existing PST files - which I still have (untouched). and then just after 2 hours I find out, that it's not possible to have IMAP and POP3 in the same PST file... ok great, all for nothing... Anyways, I'm having 11'000 files sorted in that PST file and I have created almost 100 rules to move the mails - especially Spam to (spam)-folders, as I wanted it to work... ...as sometimes you're not 100% sure if it is spam... or it is not spam, but just not important currently, so I have moved thos mails automatically into folder, where I would easily find those mails later again. NOW... after I did read in a forum, that I need to delete the Outlook Profile completely in order to allow me to have my PST back accepted... ...I still don't manage to have the imap account deliver emails to my existing PST file! --> Can you please tell me, what I need to do, in order to get my imap account deliver emails again to my existing PST file? I can enter the PST file to the data files, no problem with that... ...BUT: when I then the imap account always creates a copy of that PST file and delivers the mails to that copy...! WHAT can I do? PS. I've tried already ForcePSTPath in Registry, but this only gives some error messages (well first it seems to help to kick out other PST files, that I haven't been able to kick out, but after that I was created anyways again automatically, which I don't want. Thank you so much in advance for your help! best regards, Lukas
