<p>Microsoft has released a fixed version of the Microsoft Exchange Server 2013 security update, which originally arrived last week during patch Tuesday and was then swiftly pulled.</p><p>The company released the fixed version of the patch recommending that businesses update their systems to run it as soon as possible. "Microsoft re-released this bulletin to announce the reoffering of the 2843638 update for Active Directory Federation Services 2.0 on Windows Server 2008 and Windows Server 2008 R2," read the update.</p><p>"For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service."</p><p>The update was originally released last week as a part of Microsoft's regular Patch Tuesday. But Microsoft pulled the update days later, following reports it was blocking users from searching their email inboxes. The pull was doubly complex as many companies had already installed the patch, but Microsoft said the new patch will still work for those who installed the original.</p><p><a href="http://www.v3.co.uk/v3-uk/news/2289950/microsoft-rereleases-critical-exchange-server-2013-security-fix">Keep reading...</a></p><p>Read also:</p><p><a href="http://www.theregister.co.uk/2013/08/20/ad_security_fix_reissued/">Second time&#039;s a charm!
