I have being having a problem with both ms outlook and outlook express for quite some time now. In outlook express it tells me that Msimn.exe has generated errors and will be closed by windows. You will need to restart the program. An error log is being created.Ms outlook gives something similar to that .I have applied the resolutions provided in microsoft even modifying the registry all in vain. All this started when I created another profile and replaced the previus pst file with the file of this new profile and prior to this both programs were ok, but the puzzle is how comes outlook express got affected by this??. For OE ,I have re-installed IE &OE .This error comes when I click send/ receive . Any Help ?
I have win 2000 sp4 with office 2003
