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 and Shell infrastructure permissions topic.


Parameter Required Type Description




The Force switch specifies whether to suppress warning or confirmation messages. This switch can be used when the task is run programmatically and prompting for administrative input is inappropriate. If the Force switch isn't provided in the command, you're prompted for administrative input. You don't have to specify a value with this parameter.

By default, the Update-ExchangeHelp cmdlet has a throttling period of one hour. If you run this cmdlet within one hour of the last time you ran it, it won't check for updates. You can use the Force switch to bypass the throttling restriction and force the cmdlet to check for updates.
