Unable to create an instance of "ActivityManager" using Powershell?

Question

Would like to work with the "ActivityManager" object however it is throwing an error:

$site = New-Object Microsoft.SharePoint.SPSite($siteurl)
$context = [Microsoft.Office.Server.ServerContext]::GetContext($site)
$upm = New-Object Microsoft.Office.Server.UserProfiles.UserProfileManager($context)
$profile = $upm.GetUserProfile([string]$loginname)
$am = New-Object Microsoft.Office.Server.ActivityFeed.ActivityManager($profile, $context)

Error:
New-Object : Cannot find an overload for "ActivityManager" and the argument count: "2".

any help?

Ok,it helps

$siteurl = "http://siteurl/";
$loginname = "domain/user";
$site = New-Object Microsoft.SharePoint.SPSite($siteurl);
$context = [Microsoft.Office.Server.ServerContext]::GetContext($site);
$ServerContext = Get-SPServiceContext $site;
$upm = New-Object Microsoft.Office.Server.UserProfiles.UserProfileManager($context);
$profile = $upm.GetUserProfile([string]$loginname);
$am = New-Object Microsoft.Office.Server.ActivityFeed.ActivityManager($profile, $ServerContext);

any help how can I deselect the "Manager change" newsfeed settings?

Answer 1

It takes two arguments:

public ActivityManager(
    UserProfile userProfile,
    SPServiceContext serviceContext
)

You are giving it a Microsoft.Office.Server.ServerContext, not a SPServiceContext.

Answer 2

To deselect a News feed setting, you would have to get the ActivityType from the ActivityTypes collection of ActivityManager class. And then use the IsSet property of the ActivityPreferencePerType to set the news feed to false.

But bear in mind that Microsoft disallows these settings from being changed by anyone except for the user who owns the account. In your case, running the code via console command while logged in as the farm administrator is not equal to the user's account for which the settings apply.

You can make a work around by somehow having the user run this code
