I solved it by removing the top level folder creation lists in exchange 5.5. I made it none. I got the clue from the exchange setup log: failed, returning error code -2147467259 (An unknown error has occurred.). -- ID:31136 -- ScCreateProcess (f:\titanium\admin\src\libs\exsetup\hiddenw1.cxx:1821) There is not a single place or KB which connects to this issue.Its not documented yet for the geberal public as of now. Thanks for your responses. This is a great group. Dominic@india,mumbai ----- Original Message ----- From: Michael B.
