Summary

Consider the following scenario:
  • You are using Microsoft Outlook 2013.
  • You are connected to a Microsoft Exchange Server mailbox.
  • Your Exchange email account is configured to use Cached Exchange Mode.
In this scenario, when you use the Empty Folder command to delete the contents of the Deleted Items folder, only a subset of items are deleted. Similarly, when you use the Delete All command to delete the contents of other Outlook email folders, only a subset of items are deleted. Additionally, if you enable the Empty Deleted Items folders when exiting Outlook option, only a subset of items are deleted from any Deleted Items folders when you exit Outlook.

More information

This behavior occurs because of the new Cached Exchange Mode Sync Slider feature that is introduced in Outlook 2013. By default, Sync Slider is set to synchronize only the last 12 months of email messages and deleted items. In the default configuration, only the last 12 months of items are displayed in the email and Deleted Items folders. When you click the Delete All command, only the email messages that are displayed in the folder are deleted. If you browse to the Deleted Items folder and then click the Empty Folder command, only the email messages that are displayed in the folder are permanently deleted. The same is true if you enable the Empty Deleted Items folders when exiting Outlook option. When you exit Outlook, items more than 12 months old are not permanently deleted.
