Heeding the advice of respected authorities I'll switch the internals
to Redemption as soon as possible. For now I'll migrate my code into
an add-in.

Thank you kindly.

No version of Outlook should ever be run in a Windows service. It's not that
it's not a good idea, it's a really bad idea. Outlook puts up all sorts of
user prompts and there's no way to disable them. That's aside from the user
impersonation issues. You'll never find anyone who recommends using Outlook
in a service. If you must do something like that use CDO 1.21 or Extended
MAPI or Redemption instead in the service.
