After removing Outlook 2007 from all of the computers in our office, I ran into a few problems putting 2003 back on. When loading outlook, the error that the .ost file is not a valid folders file came up. So I decided to go into control panel, and head into the mail section to remove some profiles and re-add them. Upon trying to add an exchange server account the following message appeared: “There was an error locating one of the items needed to complete this operation. It might have been deleted” Sentinel had the answer, all you need to do is so a search for 'mapisvc.inf' on your C: drive. It will find 2 files, one in C:\Windows\System32, one in C:\Program Files\Common Files\System\MSMAPI\1033 I renamed both of them to mapiscv_old.inf - call it what you like, delete it if you are feeling game. Then run Outlook 2003, it will configure and put the file back there for you, and allow you to setup your account.
