Outlook 2007 Client - "The item could not be downloaded." 80070005

Exact Error Message
"The item could not be downloaded." 80070005

Details:
When using Outlook 2007 to open archived items, the message "there was an error loading this item -- some functionality may not be available " and the pop box "The item could not be download" is returned (see Figure 1).

Figure 1



A client trace will show the line

CShortcutItem::Display...Return Last Failed error: 0x80070005

However if the client is changed to Outlook 2003 the item can be viewed as expected.

Resolution:

The issue could be due to a restriction in the environment that prevents the use of PST files. Changing the Download Format of an item from a DVS file to an MSG file can resolve the issue (see Figure 2).

1. Log onto the Enterprise Vault (EV) server and open the Vault Administration Console (VAC)

2. Browse to the Exchange Mailbox Policy (EV 2007 and earlier) or Exchange Desktop Policy (EV 8.0 or higher) and select the properties of the Policy

3. On the Advanced Tab, select Desktop (EV 6.0 and 7.0) or Outlook (EV 2007 and 8.0) from the "List Settings from" drop down box.

4. Change the Download Format from DVS to MSG and synchronize all mailboxes to have the change take effect.
