I love when Microsoft fails to regression test their software updates, especially ones that are deemed critical and install themselves! This one is more under the clients control, nor would i recommend ever installing a major update like this without sand-boxing first. Luckily it can be uninstalled correctly and easily… why are people still using public folders anyways?
A small number of customers have reported when the Outlook client is used to move or copy a folder that subfolders and content for the moved folder are deleted. After investigation we have determined that the folder and item contents do not appear in the destination folder as expected but may be recovered from the Recoverable Items folder (what was previously known as Dumpster in older versions of Exchange) from the original folder. This behavior occurs due to a customer requested change in SP1 RU4 which allowed deleted Public Folders to be recovered. Outlook and Exchange are not correctly processing the folder move and copy operations causing the folder contents to appear to be deleted. OWA and Exchange Web Services clients are not affected by this change and process the folder move or copy actions correctly.
