I've recently got the problem when archived item couldn't opened neither in Outlook nor in OWA. In OWA it offered to open the item directly from EV server. But when I tried to do that I've got an error:

GetOnlineAttachmentFileSize 0xC00420C8

Searching for solution didn't help. I've found one forum post but only suggestion was to open Symantec case. So I tried to find the reason myself. I found the DVS file but couldn't it open directly due to reasons specified  here. When I created an HTML provided and tried to open this saveset by using vault ID and transaction ID provided I've got an error:

Archive, Archive Folder, Vault Store or Retention Category does not exist.

I've checked vault ID and found out there is no such one. When I found the archived item in the archive search and checked the folder where it is I've found out it was in different folder. So that was a reason of inability to open archive item from Outlook or OWA.

So next step was to fix vault ID in the shortcut. Using MFCMAPI I have modified proper MAPI property (Tag: 0x84ED001E; Named Prop Name: sz: "Archive ID"). After that the item was opened without any problems
