Microsoft has withdrawn Update Rollup 8 for Exchange Server 2010 SP3. One of the issues caused by the update is that Outlook 2010 clients can no longer connect to an Exchange server. According to Heise the Update Rollup 8 for Exchange Server 2010 SP3 causes connection problems with the groupware server after installation. Some users of Outlook 2010 can no longer open their sent items and also the calendar function appears to be affected.
Microsoft has acknowledged the problems but states the issues only affect servers running SP3 version of Exchange Server 2010, systems running SP2 and SP1 shouldn’t be affected. The software giant has decided to withdraw the Update Rollup 8 until further notice. The company is working on a fix for the issues. Microsoft recommends companies and organisations that already installed the affected Update Rollup to delete it using the rollback feature .
Besides the issue with an update for Exchange Server 2010 SP3, also update KB3002339 for Microsoft Visual Studio appears to be buggy, some users report they can’t install the update on their system. The root of that problem isn’t known yet.
Microsoft had to withdraw several updates this year already, in August this year an update to Windows 8.1 caused boot failures, in September the company withdrew an update for Lync and in November an SSL update caused issues.
