xExchange

The xExchange module contains many DSC resources for configuring and managing Exchange 2013, 2016, and 2019 servers including individual server properties, databases, mount points, and Database Availability Groups.

This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact opencode@microsoft.com with any additional questions or comments.

Branches

master

This is the branch containing the latest release - no contributions should be made directly to this branch.

dev

This is the development branch to which contributions should be proposed by contributors as pull requests. This development branch will periodically be merged to the master branch, and be released to PowerShell Gallery.

Contributing

Please check out common DSC Resources contributing guidelines.

Installation

To manually install the module, download the source code and unzip the contents of the '\Modules\xExchange' directory to the '$env:ProgramFiles\WindowsPowerShell\Modules' folder.

To install from the PowerShell gallery using PowerShellGet (in PowerShell 5.0) run the following command:

Find-Module -Name xExchange -Repository PSGallery | Install-Module

To confirm installation, run the below command and ensure you see the SQL Server DSC resources available:

Get-DscResource -Module xExchange

Requirements

The minimum Windows Management Framework (PowerShell) version required is 4.0, which ships with Windows Server 2012 and Windows Server 2012 R2, but can also be installed on Windows 2008 R2 (the minimum supported OS version for Exchange Server 2013).

Note that while the xExchange module may work with newer releases of PowerShell, the Microsoft Exchange Product Group does not support running Microsoft Exchange Server with versions of PowerShell newer than the one that shipped with the Windows Server version that Exchange is installed on. See the Windows PowerShell section of the Exchange Server Supportability Matrix for more information.

Examples

You can review the Examples directory in the xExchange module for some general use scenarios for all of the resources that are in the module.

Common Issues

The parameter Name can be a breaking setting. When you change the name the identity changes as well. The switch InstallIsapiFilter by the Cmdlet is doing nothing. Therefore Add-WebConfigurationProperty is used to add a missing IsapiFilter.

xExchAntiMalwareScanning

xExchAntiMalwareScanning is used to enable or disable Exchange Anti-malware scanning.

• Enabled: Whether Exchange Anti-malware scanning should be Enabled.
• Credential: Credentials used to establish a remote PowerShell session to Exchange.

xExchAutoMountPoint

xExchAutoMountPoint is used to automatically find unused disks, and prepare them for use within AutoReseed. With the disks that are found, it will assign appropriate volume and database mount points. Once fully configured, if a disk fails and is replaced with a new disk, xExchAutoMountPoint will automatically detect it and format and assign an Exchange volume mount point so that AutoReseed can detect it as a spare disk.

• Identity: The name of the server. This is not actually used for anything.
• AutoDagDatabasesRootFolderPath: The parent folder for Exchange database mount point folders.
• AutoDagVolumesRootFolderPath: The parent folder for Exchange volume mount point folders.
• DiskToDBMap: An array of strings containing the databases for each disk. Databases on the same disk should be in the same string, and comma separated. Example: "DB1,DB2","DB3,DB4". This puts DB1 and DB2 on one disk, and DB3 and DB4 on another.
• SpareVolumeCount: How many spare volumes will be available.
• EnsureExchangeVolumeMountPointIsLast: Whether the EXVOL mount point should be moved to be the last mount point listed on each disk. Defaults to $false.
• CreateSubfolders: If $true, specifies that DBNAME.db and DBNAME.log subfolders should be automatically created underneath the ExchangeDatabase mount points. Defaults to $false.
• FileSystem: The file system to use when formatting the volume. Defaults to NTFS.
• MinDiskSize: The minimum size of a disk to consider using. Defaults to none. Should be in a format like "1024MB" or "1TB".
• PartitioningScheme: The partitioning scheme for the volume. Defaults to GPT.
• UnitSize: The unit size to use when formatting the disk. Defaults to 64k. Specified value should end in a number, indicating bytes, or with a k, indicating the value is kilobytes.
• VolumePrefix: The prefix to give to Exchange Volume folders. Defaults to EXVOL

Common Issues

xExchAutoMountPoint will not assign an Exchange database mount point if the target folder for the database already exists. If initial setup fails, make sure that the database folders do not already exist. Note that this only affects database folders. If a volume folder already exists, the resource will just find the next unused number and assign it to a new volume folder.

xExchClientAccessServer

xExchClientAccessServer is used to configure properties on a Client Access Server.

Where no description is listed, properties correspond directly to Set-ClientAccessService parameters.

• Identity: The hostname of the Client Access Server.

Common Issues

DAG creation will fail if the computer account of the node managing the DAG does not have permissions to create computers in Active Directory. To avoid this issue, you may need to make sure that the computer account for the DAG is prestaged. To disable PreferenceMoveFrequency you have to use the following value: "$(([System.Threading.Timeout]::InfiniteTimeSpan).ToString())"

xExchDatabaseAvailabilityGroupMember

xExchDatabaseAvailabilityGroupMember adds a member to a Database Availability Group. This must be implemented by all nodes, including the one that creates and maintains the DAG.

xExchJetstress

xExchJetstress automatically runs Jetstress using the JetstressCmd.exe command line executable. The resource launches Jetstress via a Scheduled Task, then monitors for JetstressCmd.exe to determine whether Jetstress is running. Once JetstressCmd.exe has finished, xExchJetstress looks for the existence of TYPE.html* files in the Jetstress installation directory to determine whether Jetstress has already been run, or if it needs to be executed. TYPE corresponds to the Type defined in the JetstressConfig.xml file, where valid values are Performance, Stress, DatabaseBackup, or SoftRecovery. If TYPE*.html files exist, the newest file is inspected to determine whether the Jetstress run resulted in a Pass or Fail. Note that a TYPE.html* file is not written until Jetstress has finished its initialization phase, and has also finished the testing phase with either a Pass or a Fail. A crash of the JetstressCmd.exe process will also prevent the file from being written.

• Type: Specifies the Type which was defined in the JetstressConfig.xml file:{ Performance | Stress | DatabaseBackup | SoftRecovery }
• JetstressPath: The path to the folder where Jetstress is installed, and which contains JetstressCmd.exe.
• JetstressParams: Command line parameters to pass into JetstressCmd.exe.
• MaxWaitMinutes: The maximum amount of time that the Scheduled Task which runs Jetstress can execute for. Defaults to 0, which means there is no time limit.
• MinAchievedIOPS: The minimum value reported in the 'Achieved Transactional I/O per Second' section of the Jetstress report for the run to be considered successful. Defaults to 0.
• WARNING 1: Jetstress should NEVER be run on a server that already has Exchange installed. Jetstress is only meant to be used for pre-installation server validation. As such, it is recommended that xExchJetstress be used in a one time script which is separate from the script that performs ongoing server configuration validation.
• WARNING 2: xExchJetstress should NOT be used in the same configuration script as xExchJetstressCleanup. Instead, they should be run in separate scripts. Because xExchJetstress looks for files and folders that may have been cleaned up by xExchJetstressCleanup, using them in the same script may result in a configuration loop.

xExchJetstressCleanup

xExchJetstressCleanup cleans up the database and log directories created by Jetstress. It can optionally remove mount points associated with those directories, and can also remove the Jetstress binaries. Note that xExchJetstressCleanup does NOT uninstall Jetstress. That can be accomplished using the Package resource which is built into DSC.

• JetstressPath: The path to the folder where Jetstress is installed, which contains JetstressCmd.exe.
• *ConfigFilePath: The full path to JetstressConfig.xml, which will be used to determine the database and log folders that need to be removed.
• *DatabasePaths: Specifies the paths to database directories that should be cleaned up.
• DeleteAssociatedMountPoints: Indicates that the mount points associated with the Jetstress database and log paths should be removed. Defaults to $false. Does not remove EXVOL mount points.
• *LogPaths: Specifies the paths to log directories that should be cleaned up.
• RemoveBinaries: Specifies that the files located in JetstressPath should be removed. If ConfigFilePath is also specified and JetstressConfig.xml is in the same directory as JetstressPath, all files will be removed from the directory except JetstressConfig.xml.
• OutputSaveLocation: If RemoveBinaries is set to $true and Jetstress output was saved to the default location (JetstressPath), this specifies the folder path to copy the Jetstress output files to.

Note: Either ConfigFilePath, or DatabasePaths AND LogPaths MUST be specified. ConfigFilePath takes precedence over DatabasePaths and LogPaths.

WARNING: xExchJetstress should NOT be used in the same configuration script as xExchJetstressCleanup. Instead, they should be run in separate scripts. Because xExchJetstress looks for files and folders that may have been cleaned up by xExchJetstressCleanup, using them in the same script may result in a configuration loop.

By default, group metrics are generated only on servers that generate OABs. Group metrics information is used by MailTips to inform senders about how many recipients their messages will be sent to. You need to use this parameter if your organization doesn't generate OABs and you want the group metrics data to be available.
• IsExcludedFromProvisioning: The IsExcludedFromProvisioning parameter specifies that the Mailbox server isn't considered by the OAB provisioning load balancer. If the IsExcludedFromProvisioning parameter is set to $true, the server won't be used for provisioning a new OAB or for moving existing OABs.
