Delete or archive older calendar items

Over time, all of your saved calendar items might add up to a large number and occupy a large amount of space in your data file. To free some of this space, you can reduce the number of saved items by archiving or deleting them.

What do you want to do?

Archive your calendar items

The archive process deletes items from your data file after first making a backup of the items in another Outlook data file.

  1. Click the File tab.

  2. Under Mailbox Cleanup, click Cleanup Tools.

  3. Click Archive.

    Note:  Some organizations turn off the ability for users to create Outlook Data Files (.pst) which are used for archiving items. If you do not see Archive command, your organization may have turned this feature off.

  4. Click Archive this folder and all subfolders.

    If you created additional calendars, selecting this setting will archive items from those calendars as well.

  5. In the folder list, click Calendar.

    Archive dialog box

  6. In the Archive items older than list, select the date that you want. To archive everything, select a date in the future.

  7. If you want, select the Include items with "Do not AutoArchive" checked check box.

    Selecting this check box will archive everything, including items that you marked as exceptions to AutoArchive.

  8. You can accept the file location where the archive file will be saved, or you can browse to a different folder and provide the file name of your choice.

    Note:  We recommend that you make a note of this location so that you can easily find the archive file later.

  9. Click OK.

    The archiving process begins. When you return to the main Outlook view by clicking the Home tab, the Outlook status bar indicates that the archive is in progress.

    Archiving status bar

    To cancel the archive in progress, click Archiving stop button . Any items that were already archived up to that point will remain in the archive file.
