Update Rollup 4 (UR4) for Exchange Server 2010 SP1 removed from downloads

This entry was posted by on Wednesday, 20 July, 2011 at

Microsoft has discovered an issue impacting some customers who have installed
Exchange 2010 SP1 RU4 into their Exchange environment and as a result have
removed SP1 RU4 from Download Center and recommend customers do not proceed with
any planned deployments of SP1 RU4.

 

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.

 

Microsoft will be providing a fix in Exchange 2010 SP1 RU5, scheduled for release in
August, which prevents the content loss in the target location during the
move/copy process. In addition, we are also working with the Outlook development
team to examine their code for proper behavior and identify if a fix is
necessary from the client. If you have already deployed SP1 RU4, Microsoft recommend
obtaining an Interim Update that resolves this issue.

 

If you are a customer seeing this issue or would like to receive the Interim
Update, please contact Microsoft Customer Support.  When contacting Microsoft Customer Support, you can
reference KB 2581545 (please note that this article will be available at a later
date on support.microsoft.com).  When installing the Interim Update, you need to
install this on all Client Access and Mailbox servers that have SP1 RU4
installed.
