Messages not moved after filing
Symptoms:
After filing, messages don't get moved to Filed Items or Deleted Items.
Cause:
The message is not cached i.e. when you have had to select “Click here to view more on Microsoft Exchange” to list the messages.
Workaround:
Temporarily configure Outlook to download all emails (see "Cached Exchange Mode")
Once all the emails have been downloaded, it may take a while, they can then be filed.
