Microsoft Outlook 2007We always recommend that you disable the Auto Archive option in Outlook. The Auto Archive option will remove any email that is older than 6 months from your mailbox and place it into a file on your local hard drive as a .PST file. We don’t recommend this because the email that you archive will be taken off of the mail server and onto your workstation. It will no longer be backed up and if your workstation were to die, that archive has a good chance of dying with it. To disable this feature do the following…
To disable Auto Archive, start by clicking on Options under the Tools menu.Click on the AutoArchive button on the Other tab.
Uncheck the Run AutoArchive every checkbox. This will disable Auto Archive. Once you are finished, click OK twice.
