Do we need to install Aug SUv2?<\/em><\/strong><br \/>\nNo. In environments that have manually installed original release (Aug SUv1) and installation completed with no errors, <em>installation of Aug SUv2 is optional<\/em>.<\/p>\n<p><strong><em>We installed the original Aug SUv1 through Microsoft \/ Windows Update and had no problems. Will our server install Aug SUv2 automatically?<\/em><\/strong><br \/>\nYes. The version of re-released August SU package is higher than the version of the original August SU release and servers enrolled into getting updates through Windows Update will automatically get the new re-released version.<\/p>\n<p><strong><em>What are the differences between Aug SUv2 and Aug SUv1 update packages?<\/em><\/strong><br \/>\nThe only difference between original release and re-release of August 2023 SU package is the resolution of the localization issue that was causing the original release of August SU to fail on non-English OS servers. There are no other changes. <a href=\"https:\/\/techcommunity.microsoft.com\/t5\/exchange-team-blog\/released-august-2023-exchange-server-security-updates\/ba-p\/3892811\" target=\"_blank\" rel=\"noopener\">The original release blog post<\/a>, CVEs, and post-installation recommended actions still apply.<\/p>\n<p><strong><em>What would happen if we installed the Aug SUv1 by following the workaround and don&#8217;t uninstall it as recommended?<\/em><\/strong><br \/>\nIf you&#8217;re running Exchange Server on a non-English OS and were only able to install the Aug SUv1 by following the workaround we provided, you should uninstall the Aug SUv1 first. If you don\u2019t remove the Aug SUv1, the requirement for the dummy \u201cNetwork Service\u201d account will remain and persist with any future SUs that are applied to the CU version that is installed on the machine.<\/p>\n<p>In other words: If you used the workaround, and <em>don\u2019t uninstall Aug SUv1 <\/em>but you delete the &#8220;Network Service&#8221; dummy account, then installation of Aug SUv2 (or later SUs) will fail with the same behavior as Aug SUv1.<\/p>\n<p><strong><em>If we need to uninstall Aug SUv1, will that have any impact on CVE-2023-21709 actions we already took?<\/em><\/strong><br \/>\nNo. Addressing CVE-2023-21709 either manually or by using the script that we provided is not directly related to installation of August 2023 SU package. Even if you remove Aug SUv1, you do not need to re-do anything you did to address CVE-2023-21709. The remaining August 2023 CVEs are tied to August SU package and installing Aug SUv2 (or later SUs, when released) will address those. If you have not yet addressed CVE-2023-21709, you can do so at any time.<\/p>\n<p><em><strong>We installed original Aug SUv1 using Windows Update and the full workaround (and we left the &#8216;Network Service&#8217; account in place). When Microsoft re-released Aug SUv2, Windows Update installed Aug SUv2. We cannot uninstall SUv1 as it does not show installed anymore. Is there anything that we should do?<\/strong><\/em><br \/>\nIn this case, the requirement for the &#8216;Network Service&#8217; dummy account carries forward. To break the chain of dependency on this account (started with Aug SUv1) we recommend you do the following:<\/p>\n<ul>\n<li>Uninstall SUv2 (because SUv2 replaced SUv1 on your server) and reboot<\/li>\n<li>Remove the &#8220;dummy&#8221; Network Service account<\/li>\n<li>Re-install SUv2 as if SUv1 never existed<\/li>\n<\/ul>\n<p>Performing those steps will ensure that the dependency on the dummy &#8216;Network Service&#8217; account does not carry forward to future SUs.<\/p>\n<p><strong>Changes to this blog post:<\/strong><\/p>\n<ul>\n<li>8\/18: Added references to KB articles for two updates so they can be differentiated easier<\/li>\n<li>8\/18: Added a FAQ on what to do if SUv2 was already installed over SUv1 after full workaround was used<\/li>\n<\/ul>\n<p><font color=\"#CF3600\">The Exchange Server Team<\/font><\/p>\n<\/div>\n<p><a href=\"https:\/\/techcommunity.microsoft.com\/t5\/exchange-team-blog\/re-release-of-august-2023-exchange-server-security-update\/ba-p\/3900025\">Read full article (Microsoft Exchange Blog)<\/a><\/p>\n<p>All content and images belong to their respected owners, this article is curated for informational purposes only.<\/p>\n","protected":false},"excerpt":{"rendered":"Today we are re-releasing the August 2023 SUs for Exchange Server.
