Documentation and parameter text: Microsoft, CC BY 4.0; formatting adapted by Cmdlet World. No execution testing is claimed.
Use an account with the target resource permissions documented for Grant-FileShareAccess. Modifying administrative cmdlets may require elevation or delegated administration. This catalog does not assert that ordinary users can execute the command.

Parameters
-AccessRight (required)
Specifies the access rights for the accounts. The acceptable values for this parameter are: - Full - Modify - Read - Custom
-AccountName (required)
Specifies an array of account names. This cmdlet grants file share access to the account names that you specify.
-AsJob
Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-Confirm
Prompts you for confirmation before running the cmdlet.
-FileServer
Specifies a file server.
-InputObject (required)
Specifies the input object that is used in a pipeline command.
-Name (required)
Specifies an array of file share names. This cmdlet grants access to the file share names you specify. Because the file share name is not a worldwide unique name, you can use a different parameter set to avoid confusion.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
-UniqueId (required)
Specifies an array of unique IDs of file shares.
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
Prerequisites
Windows with the Storage module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.
Security considerations
This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
