I don't know if this will work for everyone but it did for me. My Outlook 2013 would stay active for 40 seconds then stop. I deleted my OST file. When I reopened Outlook, all my folders were gone (understandly) ! So, I went to the Recycle Bin and "restored" my OST file. Everything was restored and I haven't had an Outlook stoppage since.



FYI the path to the OST file is:
Computer - LocalDisk(3) - Users - (username) - AppData - Local - Microsoft -Outlook
