Hi, when running mfcmapi on a SBS2003 i got this error when i log on, 0x8004010F MAPI_E_NOT_FOUND I also get this error when running mfcmapi on another computer and connect to the same exchange server. I got the error on Row Type, Depth and on many PR_ proerties. I can connect to the exchange server and the postbox and public folder shows up. From Outlook client on another computer all is okey, but i have a program thats need to connect to the Exchange server with the cdo and thats not working and that program get the same error descriptions. Is there som way to cleanup the MAPI settings on a exchange server?
