The Set-SendConnector cmdlet does not work for Exchange Server 2019 in hybrid scenarios that have a Edge server installed.

Then the Exchange admin user can start Setup. To avoid the error messages, either the user should join Schema Admins and Enterprise Admins groups, or another user in Schema Admins and Enterprise Admins groups manually runs the /PrepareAD for this Cumulative Update first.

Therefore, a domain administrator should run the /PrepareDomain in other domains in the forest.Īs the /PrepareAD is triggered in Setup, if the user who initiates Setup isn't a member of Schema Admins and Enterprise Admins, the readiness check will fail and you receive the following error messages: However, it may be unable to update other domains in the forest. The /PrepareDomain operation automatically runs in the Active Directory domain in which the /PrepareAD command is run. About the /PrepareDomain operation in multidomain: If you has ever skipped a Cumulative Update (for example, you are upgrading from an earlier version before Cumulative Update 2 for Exchange Server 2019), or this is a first Exchange Server installation in the AD, then this Known Issue section should be taken care of.Ī. No additional actions (prepareAD, prepareDomain, or assigning permissions) are required. If you are upgrading from Cumulative Update 2 for Exchange Server 2019 to Cumulative Update 3 for Exchange Server 2019, then there’s no need to run the /PrepareAD or /PrepareDomain.

Installation will finish only if the user who initiated Setup has the appropriate permissions. In multidomain Active Directory forests in which Exchange is installed or has been prepared previously by using the /PrepareDomain option in Setup, this action must be completed after the /PrepareAD command for this cumulative update has been completed and the changes are replicated to all domains. Setup will try to run the /PrepareAD command during the first server installation. For more information about DST, see Daylight Saving Time Help and Support Center. This update also includes new daylight saving time (DST) updates for Exchange Server 2019. These fixes will also be included in later cumulative updates for Exchange Server 2019. It includes fixes for nonsecurity issues and all previously released fixes for security and nonsecurity issues. This cumulative update is a security update. Cumulative Update 3 for Microsoft Exchange Server 2019 was released on September 17, 2019.
