Assuming you want to delete everything prior to a certain month (and not
just some period of time in between), the following will work. If you want
to delete say just 2001 but keep 2000 and 2002, I'm not sure it can be done.
Delete old items automatically
1.. Right-click the folder that contains the items you want to delete
automatically, and then click Properties on the shortcut menu.
2.. Click the AutoArchive tab.
3.. To enable automatic archiving of this folder, select the Clean out
items older than check box.
4.. To specify when items should be deleted, enter a number in the months
box.
5.. To have items automatically deleted, click Permanently delete old
items.
Note To activate AutoArchive, you must turn on AutoArchive before setting
individual folder properties. On the Tools menu, click Options, click the
Other tab, and then click AutoArchive. Select the AutoArchive every check
box.
