A Guide to Microsoft Outlook Archiving

written by: •edited by: Christian Cawley•updated: 4/23/2011

Microsoft Outlook archiving is about moving your old but important data to a separate file so that the files in use do not become too big for Outlook to handle. This is different from exporting and backing up your messages, as we explain below...

    Archiving vs Backing Up

    Microsoft Outlook archiving may look similar to backing up emails. However, there is a huge difference between Microsoft Outlook archiving and backing up Outlook items. When you back up Outlook items, you copy them to a different file. The file can be of any format - PST, Excel sheet or text file. Microsoft Outlook archiving on the other hand, moves old but important items from your Outlook folders to a separate file.

    This means that when you back up items, they still appear in their relevant folders. When you archive, the items are moved and do not appear in the folders where they were present initially. With Microsoft Outlook archiving feature, you can create only a PST file (which can be opened only with Microsoft Outlook). If you want to see the archived items at a later time, instead of importing the file using the Import Export wizard, you need to add it using the Data tab in Account Settings window of Microsoft Outlook.

    If you are looking for information on backing up Outlook emails, please read our article How to Back up Outlook Emails? This article explains Microsoft Outlook archiving features.

    Microsoft Outlook Archiving Tools

    Fig 1 - Microsoft Outlook Archiving - Auto Archive Settings Dialog Outlook allows you to manually or automatically archive your messages. Microsoft Outlook has an auto archiving feature that helps you archive your messages, tasks and calendars at regular intervals. When you install Microsoft Outlook, the Auto Archiving feature is turned ON automatically and the time-interval for running the auto archive wizard is set to 14 days.

    This means that the Microsoft Outlook Auto Archiving wizard will run every 14 days unless you specify otherwise. The Auto Archiving wizards checks for OLD items in all your folders and moves them to a separate file. For example, if you have email messages that are more than six months old, the Auto Archive wizard will move them to a separate PST file. When it starts, the Microsoft Outlook Auto Archiving wizard will prompt you asking if you wish to archive your Outlook items. To continue, click Yes and to cancel the wizard, click No.

    Note that the default Auto Archive settings for Sent Items and Deleted Items is only two months as against six months for other folders.

    Changing Auto Archive Settings

    You can open the Auto Archive Settings box and change the default settings to something else. You can change:

    1. The period when you want the Auto Archive wizard to run.
    2. Whether you wish to delete the old email messages. By default, Auto Archive wizard will delete emails older than six months. If you wish to move them to the PST files along with other items, uncheck the box against Delete Expired Items (see Image).
    3. Default location and filename for archive file
    4. Change the period when the Auto Archive considers an item as OLD to move it to archive file.

    Using the settings dialog for Auto Archiving, you can also specify if you wish to delete all the old items. The default setting is to move everything except email messages, to a file that you specify.

    Note: When Microsoft Outlook Auto Archiving moves an email message to a different PST file, it also moves any attachments with that mail. However, it will not move the attachments that you stored separately on the hard disk.
