Applies to: Exchange Server 2016
This cmdlet is available only in on-premises Exchange Server 2016.
Use the Update-ExchangeHelp cmdlet to find, download, and install the latest available help topics for the Exchange Management Shell on the local computer. If an available version is found based your installed version and languages of Exchange, the cmdlet downloads and integrates the updated version of Help in the Exchange Management Shell. This cmdlet is a required substitute for the Update-Help cmdlet that's available in Windows PowerShell.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.
This example checks for the latest available version of Help for the Exchange Management Shell on the local computer. Because we used the Force switch, the command checks for updates even if you ran the command less than 24 hours ago, and displays status and error messages.
The Update-ExchangeHelp cmdlet is available in Exchange Server 2013 or later.
You need to run the Update-ExchangeHelp cmdlet on each Exchange server. By default, the cmdlet requires an Internet connection, but you can configure an offline mode. For more information, see Use Update-ExchangeHelp to update Exchange PowerShell help topics on Exchange serversUpdate-ExchangeHelp.
You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Exchange Help settings" entry in the Exchange infrastructure and PowerShell permissions topic.
The Force switch specifies whether to suppress warning or confirmation messages. You can use this switch to run tasks programmatically where prompting for administrative input is inappropriate. You don't need to specify a value with this switch.
By default, the Update-ExchangeHelp cmdlet has a throttling period of 24 hours. If you run this cmdlet within 24 hours of the last time you ran it, it won't check for updates. You can use this switch to force the cmdlet to check for updates more frequently, and to display status or error messages.
To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.
