Tidying up Office Data Files

[Glyn]

My Office Data files are in a mess. I have discovered that
I have Outlook (approx 0.8GB) and Outlook1 (approx 0.8GB)
Mailbox (32KB) and Archive (0.35GB). I created Archive
some time ago but have not archived recently. I don't know
why I have 2 Outlook files - possibly created when I
transferred data to a new laptop a few weeks ago. I would
like to re-combine everything into 1 file so that I can
start again and set up a proper Archive system again.

How can I do this without risking losing files or creating
duplicates or triplicates. As you will note the files are
very big!

Any help much appreciated.

Thanks
