Am 14. Februar 2019 wurde das Exchange Server 2019 Cumulative Update 1 zum Download veröffentlicht. Mit dieser Veröffentlichung wurde nun auch die lange erwartete Anleitung zur Konfiguration der Meta Cache Datenbank (MCDB) auf Microsoft Docs bereitgestellt. Die Funktion der MCDB ist eine optionale Funktion für den Betrieb von Datenbankverfügbarkeitsgruppen (DAG). Die Konfirguation der MCDB bietet eine Leistungssteigerung im Zugriff auf Exchange-Postfächer und die Exchange-Suche. Der Einsatz ist besonders dann anzuraten, wenn Sie große Festplatten für die Speicherung ebenso großer Postfachdatenbanken verwenden.  Die wichtigsten Voraussetzungen für die Nutzung der MCDB-Funktion in einer Exchange Server 2019 DAG sind: Alle Mitgliedserver der DAG verfügen über eine identische Festplatten- und SSD-Datenspeicher-Konfiguration Identische Reihenfolge der verfügbaren SSD-Datenspeicher im Disk Manager Bereitstellung alle SSD-Datenspeicher als RAW, also ohne eine individuelle Konfiguration Die DAG ist für Auto-Reseed konfiguriert Die Anforderung, dass die DAG für Auto-Reseed konfiguriert sein muss, macht die MCDB-Funktion nur für entsprechend konfigurierte Exchange Server Umgebungen attraktiv. Auto-Reseed wird meistens bei physikalisch betriebenen Exchange Servern verwendet, weniger mit virtualisierten Exchange Server-Systemen.  Planen Sie den Einsatz der MCDB sorgsam und folgenden Sie unbedingt den Microsoft Empfehlungen hinsichtlich ...

When you install a Cumulative Update for Exchange Server 2016 you might receive the following informational message: MAPI over HTTP, the preferred Outlook desktop client connectivity with Exchange server, is currently not enabled. Consider enabling it using: Set-OrganizationConfig -MapiHttpEnabled $true For more information, visit: http://technet.microsoft.com/library(EXCHG.150)/ms.exch.setupreadiness.WarnMapiHttpNotEnabl ed.aspx This modern protocol for Outlook has been introduced to Exchange Server with Exchange Server 2013 SP1. The protocol removes the dependency to the Windows Server RPC over HTTP component. The reduced complexity enhances the reliability of the client access protocoll. It's available for quite some time now.  You can enable MAPI over HTTP on the organization level using the following Exchange cmdlet: Set-OrganizationConfig -MapiHttpEnabled $true You can still controll the protocol setting at the user level by deactiviting MAPI of HTTP for certain users, if required: Set-CASMailbox -Identity [USER] -MapiHttpEnabled:$false If your IT infrastructue is still not ready for MAPI of HTTP, your IT components pretty outdated. It's time to move forward and to modernize the infrastructure.  NOTE Did you know that MAPI over HTTP connects to Exchange Server using TLS to encrypt the connection? Even though that the protocol name is "overHTTP" it literally uses HTTPS ...

Description The script can be used to assign an application account (e.g. CRM, ERP) send-as permission to user mailboxes to send emails AS the user and not as the application. This script loops through a membership list of an Active Directory security group. A single mailbox (CRM/ERP service account mailbox) is added to each mailbox (CRM/ERP user mailbox) of the security group members to provide send-as permission.  The script has been developed as a solution to enable proper functionality with Dynamics NAV 2016.   Examples   # Assign Send-As permission to crmapplication@varunagroup.de for all members # of 'CRM-FrontLine' security group. The mailboxes as hosted On-Premises! .\Set-SendAsPermission.ps1 -SendAsGroup 'CRM-FrontLine' -SendAsUserUpn 'crmapplication@varunagroup.de' # Assign Send-As permission to ax@granikoslabs.eu for all members of 'AX-Sales' # security group.

The PowerShell script New-RoomMailbox has been updated and release v1.2 has been published to GitHub and TechNet Gallery. The script now creates a third mail-enabled security group to limit the set of users which are allowed to book the resource. The group itself is created (prepared) only, but not assigned to the room resource. Additionally, the default language (locale) is configured. This prohibits the "Set locale" - dialogue when accessing the room mailbox using Outlook on the Web.  Read more here: https://www.granikos.eu/en/justcantgetenough/PostId/337/create-a-new-room-mailbox-with-security-groups Enjoy Exchange.

Exchange Server extends the Active Directory schema during the PrepareSchema step during setup. The steps PrepareAD, PrepareDomain, or PrepareAlLDomains create Active Directory containers and objects that are crucially important for a stable operation of Exchange Server. There are different Active Directory objects that are used to determine, if Active Directory has a proper Exchange Server configuration up and running. Forest level At Active Directory forest level the following attributes are used to determine the Exchange Server release: rangeUpper attribute of the ms-Exch-Schema-Version-Pt schema object  msExchProductId attribute of the Exchange organization object in the configuration partition objectVersion attribute of the Exchange organization object in the configuration partition objectVersion of the Microsoft Exchange System Objects (MESO) container  Domain level At Active Directory domain level the following attribute is used to determine the Exchange Server release: objectVersion of the Microsoft Exchange System Objects (MESO) container    I have written a PowerShell script to fetch all required information for all domains in an Active Directory forest.
