You're not making much sense here, mainly because you left out your
configuration. Starting the story from the beginning would be much better.

An archive folder in the Outlook sense means that you have a separate
pst-file containing archived information. This is not server related so your
error "the server is not available" was not about your pst-file.

So again, start from the beginning, where do you keep what, in which version
of Outlook and with what kind of mail account type.
