Sometimes e-mail messages do not appear in your Cached mode Inbox even though they were synchronized down from your mailbox

Symptoms

Sometimes e-mail messages do not appear in your Cached mode Inbox even though they were synchronized down from your mailbox. You can see the items in your Inbox using Online mode or Outlook Web Access or Outlook Web App (OWA), you just cannot see them in your Cached mode profile.

Cause

This problem has been known to occur when the messages are stuck in the incoming item processing pipeline, a feature first introduced by Outlook 2007. This pipeline uses the hidden ItemProcSearch folder in your mailbox to process messages prior to showing them in your Inbox. Note, the root cause for messages becoming stuck in the pipeline has not yet been determined.

Resolution

To resolve this problem, use one of the following methods.
  1. Start Outlook with the /cleanips switch
    1. Exit Outlook if it has been started.
    2. Start Outlook using the following command-line (Click Start and then click Run)

      Outlook.exe /cleanips

    Note, in order to use this switch you need at least Office 2007 Service Pack 2 installed for Outlook 2007. Later versions of Outlook have this functionality built into the product.

  2. Clear the offline items in your Inbox so they can re-synchronize

    If, for some reason, the /cleanips switch does not resolve the issue, please try the following steps to re-synchronize the items in your Inbox folder.
    1. Start Outlook.
    2. Right-click the Inbox folder and then click Properties.
    3. In the Inbox Properties dialog box, select the General tab.
    4. Click Clear Offline Items.
    5. Click OK when advised Your data was removed from your Outlook data file (.ost).
    6. Click OK in the Inbox Properties dialog box.
    7. With your Inbox selected in the Navigation Pane, press Shift + F9 to force the re-synchronization of your Inbox folder.

More information

If things are working as expected in Outlook, when new messages are synchronized into the mailbox they are temporarily “hidden” so they can be processed by the ItemProcSearch search folder. At this time, the ItemProcSearch search folder receives a notification that a new message has arrived and starts the incoming item processing. After the item has been processed it is marked as “unhidden” and you then see it in your Inbox.

When this problem occurs, this notification fails to reach the ItemProcSearch search folder. Therefore, after the incoming message is flagged as hidden, it will never be processed by the ItemProcSearch search folder to flagged it as “unhidden”.
