After configuring one simple mailbox processor scheduler starts to import emails, but seems that it does not complete whole process. It does not delete messages (it is configured to do so), so it keeps importing already imported messages. Since no source is currently available, I looked through CheckEmails() function through Reflector.
At start it queries registry for lastDate and lastMsgID settings - but nowhere in whole registry I found that values which seems the reason why it keeps repeatedly importing already imported messages and somwhere failing to delete them. Attachments are also not imported, but it might be because it throws exception somewhere before. Return value of RegistryHelper Set* functions is not checked while they're called, and it might be false (it fails and returns false on creation of reg keys). I've tried to create keys its asking manually, but still no change (I might missed something there though). Debug is set to true, but no errors are logged there or in eventlog. Service is running under standard LocalSystem account on Windows 2003, tried to run it as other user but same behaviour.

any  ideas? :)
