14 DAY TRIAL // The most recent cumulative updates published by Microsoft for Windows 10 devices on July 16 fixes an issue that causes Exchange Server not work correctly.
The glitch was first introduced by the July 10 cumulative updates that were published as part of this month’s Patch Tuesday rollout.
Microsoft hasn’t shared too many specifics as to what cumulative updates were causing the problems, but given that Windows 10 April 2018 Update, Fall Creators Update, and Creators Update received new patches on July 16, there’s a chance all three versions were affected.
Latest updates fixing all problems
Microsoft now says that customers must install the newest cumulative updates to resolve the issues, namely KB4345421 for April 2018 Update (version 1803), KB4345420 for Fall Creators Update (version 1709), and KB4345419 for Creators Update (version 1703).
“The Windows team has removed all bad packages from Windows Update and systems should no longer attempt to download an update which exposes this problem. New updates are being published through Windows Update and should be available for all operating systems by end of day July 17th,” the Exchange team says in a post originally dated July 16 and then updated a day later.
“The Exchange Team recommends that customers use Windows Update or update the catalogs on their own SUS servers to ensure the latest version of the update is available for installation on your Exchange Servers. Doing so will avoid any possible disruption to the MSExchangeTransport service which was impacted by the July 10th update.”
The original KB pages of the cumulative updates published on Patch Tuesday have also been updated to state that all known issues are fixed in the latest updates, though Microsoft hasn’t offered any specifics on the bugs experienced on Exchange Server.
The next patch Tuesday will take place on August 14, and new cumulative updates for all Windows 10 versions are obviously expected.
