Username's skype status is showing "Presence unknown" on a site collection, while it is working well on the other site collections

Question

I have the following problem, inside our sharepoint on-premises 2013, which we did NOT configure any user profile managed service for it.

1. on our root site collection, i have noted that certain user have his Skype status as "Presence unknown", when i hover over the ModifiedBy & CreatedBy list fields, as follow:-

2. where inside the Skype popup windows, i can see that the following fields; (username + Send Email link + IM) are showing an old email address for the user as follow [email protected] instead of FirstName.ALastName@ourcomany (without -). and if i click on the username, and i got redirected to /_layouts/15/userdisp.aspx?ID=** page, i can see that the username will have the following old value [email protected] inside the SIP Address, while he got the correct value inside the Work Email.

also inside other site collections, the Skype status for the user will be working fine, and if i click on the username, and i got redirected to /_layouts/15/userdisp.aspx?ID=***, the SIP address for the user will be empty, but the Skype status will show if the user is active, offline,etc, instead of "Presence unknown"..

Now i think the problem is that inside the root site collection, which we have it as the first site collection, the user's Skype id was wrong (with -), and it got added to the root site collection as-is, and after updating the user Skype id, it did not get reflected inside the user info on sharepoint. and since we do not have any user profile sync configured, so currently the Skype status is not reflecting the correct username, inside the root site collection.. So my question is how i can update the SIP address for the user or set it as empty inside the root site?? since on another site collection the user's SIP Address is empty, but he got the correct Skype status...

Answer 1

Each SiteCollection stores information about users in the hidden User Information List.

Your problem should exist in the SipAddress attribute of the user. You can confirm this with the following script:

$web = Get-SPWeb http://YourRootSite
$users = $web.SiteUserInfoList.GetItems()
foreach ($user in $users) {
  Write-Host "User: $($user.DisplayName) - SIP-Address: $($user["SipAddress"])"
}

Then you can remove all SipAddress attributes with this small modification:

$web = Get-SPWeb http://YourRootSite
$users = $web.SiteUserInfoList.GetItems()
foreach ($user in $users) {
  Write-Host "Removing SIP-Address for user $($user.DisplayName)"
  $user["SipAddress"] = ""
  $user.Update()
}

You can also modify one user by selecting a single list-item with the GetItemById(<ListEntryID>) method instead of GetItems()

Answer 2

If the data for the user is not correct in only one site, then the UPA->SP profile sync Job is ignoring the user. This is caused by the user being inactive on the site...

You can force the timer job to ignore the inactive flag by using the following command:

STSADM -o Sync -IgnoreIsActive 1

After this you need to wait a while and make sure to set it back the next day (0 as parameter instead of 1) If you are in a "smaller" company leave it on 1 (less than 10000 users) since the performance hit is not that grave and it also fixes issues with inactive users getting married or having other data changed in their profile.

You could also trigger the timer job and turn it off afterwards. I think the default is to run once an hour The timer job for SP2013 is:

User Profile service application proxy - User Profile to SharePoint full synchronization

Answer 3

Try to go to Central Administration->Manage service applications->user profile service application, start a full synchronization to update the User Profiles.
