Microsoft released hotfix updates to address known issues affecting Exchange servers post installing the March 2024 security updates. The optional April 2024 HU adds support for ECC certificates and Hybrid Modern Authentication (HMA) for OWA/ECP. Redmond fixed issues in Outlook on the Web (OWA) and Microsoft Word document previews. Both Exchange Server 2019 and 2016 are supported.
