Exchange 2010 Service Pack Flaw Detailed

Recently I told you about an Exchange 2010 SP1 rollup that got yanked after causing data to get misplaced in moved or copied folders (though there was a way to get the data back) .

Details about the cause of the problem were sketchy at the time. Now Microsoft has had time to reflect and provide an explanation. The change was an added customer-requested feature to help IT recover deleted folders, but this addition uncovered a latent flaw. Microsoft's Exchange team had deleted some Outlook code that it thought was no longer needed, but that assumption turned out not to be the case. The two teams are now collaborating on their testing processes to avoid such problems in the future.

Microsoft still advises against installing the rollup, and anyone who has installed it should contact support.
