msg

Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012

Sends a message to a user on a Remote Desktop Session Host server.

[!NOTE] You must have Message special access permission to send a message.

Syntax

msg {<username> | <sessionname> | <sessionID>| @<filename> | *} [/server:<servername>] [/time:<seconds>] [/v] [/w] [<message>]

Parameters

Parameter Description
<username> Specifies the name of the user that you want to receive the message. If you don’t specify a user or a session, this command displays an error message. When specifying a session, it must be an active one.
<sessionname> Specifies the name of the session that you want to receive the message. If you don’t specify a user or a session, this command displays an error message. When specifying a session, it must be an active one.
<sessionID> Specifies the numeric ID of the session whose user you want to receive a message.
@<filename> Identifies a file containing a list of user names, session names, and session IDs that you want to receive the message.
* Sends the message to all user names on the system.
/server:<servername> Specifies the Remote Desktop Session Host server whose session or user you want to receive the message. If unspecified, /server uses the server to which you are currently logged on.
/time:<seconds> Specifies the amount of time that the message you sent is displayed on the user’s screen. After the time limit is reached, the message disappears. If no time limit is set, the message remains on the user’s screen until the user sees the message and clicks OK.
/v Displays information about the actions being performed.
/w Waits for an acknowledgment from the user that the message has been received. Use this parameter with /time:<*seconds*> to avoid a possible long delay if the user does not immediately respond. Using this parameter with /v is also helpful.
<message> Specifies the text of the message that you want to send. If no message is specified, you will be prompted to enter a message. To send a message that is contained in a file, type the less than (<) symbol followed by the file name.
/? Displays help at the command prompt.
