For example, it isn't a supported configuration to host one copy of a given database on a 512-byte sector disk and another copy of that same database on a 512e disk or 4K disk. At this time, no additional CUs are planned for Exchange Server 2013 and Exchange Server 2016. Windows failover clusters require Windows Server 2008 R2 or Windows Server 2008 R2 SP1. Fibre Channel is an electrical interface used to connect disks to Fibre Channel-based SANs. It uses the cloud-based Office Config Service (OCS) to check for and download available mitigations and to send diagnostic data to Microsoft. Critical product updates are packages that address a Microsoft-released security bulletin or that contain a change in time zone definitions. The new Exchange admin center (EAC) is a modern, web-based management console for managing Exchange that is designed to provide an experience more in line with the overall Microsoft 365 admin experience. Mitigation of CVE-2022-41040 via a URL Rewrite configuration.
