.SYNOPSIS
Set-GraphConnectionStatus sets the status of the current connection or specified Graph.
 
.DESCRIPTION
A connection's status can be either 'Online' or 'Offline'. By default, a connection's status is 'Online,' which means that if you make requests to using the connection, an access token will be acquired if one is not already present and then a request will be sent to the Graph API endpoint for the connection via the network. To suppress token acquisition and any network access, set the connection to Offline. Its status can be later restored to 'Online'.
 
.PARAMETER Status
The status can be set to 'Online' or 'Offline'.
 
.PARAMETER Graph
The Graph is an object that contains a connection. If a Graph is specified, instead of the connection status of the current connection being changed, the status of the connection associated with the Graph parameter is updated to the value specified by the Status parameter.
 
.OUTPUTS
This command produces no output.
 
.EXAMPLE
Set-GraphConnectionStatus Offline
 
This sets the current connection's status to offline.
