\"Exchange[German<\/a>]Quick poll to the administrators among the readership who are running a Microsoft Exchange on-premises installation on Windows Server 2019. Have you experienced any performance issues with Microsoft Exchange after installing the July 2022 update? I got a report from a blog reader who had to uninstall the security update.<\/p>\n

Windows Update KB5015811<\/h2>\n

Cumulative update KB5015811<\/a> was released by Microsoft on July 12, 2022 for Windows 10 Enterprise 2019 LTSC as well as Windows Server 2019 LTSC. The patch addressed security vulnerabilities and fixed a PowerShell issue. Microsoft has not released a lot of information about this update (see Patchday: Windows 10-Updates (July 12, 2022)<\/a>). Those interested in the details of the fixes are more likely to find answers in the cumulative preview update KB5014669<\/a>.<\/p>\n

Problems with Microsoft Exchange<\/h2>\n

In a private message, German blog reader Wolfgang P. contacted me on Facebook. He runs his Exchange Server 2019 as a DAG<\/a> (Database Availability Group), but ran into nasty problems after the July 2022 patchday. Wolfgang wrote me the following:<\/p>\n

Hell G\u00fcnter,<\/p>\n

maybe you could keep an eye on it:<\/p>\n

My Exchange 2019 DAG suffered a massive performance loss after installing KB5015811. Forwarding mails of e.g. 3 MB size was acknowledged with a pop-up \"Outlook is trying to retrieve data from the server\". The process was then completed successfully, but took about 3 minutes.<\/p>\n

Uninstalled said KB on all nodes and things are running normally again. Since I haven't found any posts about this yet, I wonder if it was just me?<\/p><\/blockquote>\n

The fact that uninstalling the July 2022 update KB5015811<\/a> fixes this performance issue is a clear indication that it is related to the patches. The question is: Has anyone else encountered something similar?<\/p>\n
