Try the Get-CsUserSession cmdlet, it will spill all the details you need. You can look for &quot;[IM]&quot; values in the MediaTypesDescription property to filter just messages.

Thanks for the help! <br />
<br />
In looking up where and how to run that cmdlet, I discovered I needed to download and install the &quot;Skype for Business Online, Windows PowerShell Module,&quot; and two other installs (Visual C++ 2017 14.10.25008.0 and Win7AndW2K8R2-KB3191566-x6<wbr />4). <br />
<br />
However, now that I have those in place, I tried to run the cmdlet and get an error stating, &quot;Get-CsUserSession : The term 'Get-CsUserSession' is not recognized as the name of a cmdlet.&quot; I have tried using Windows Powershell and enter,<br />
&quot;Import-Module &quot;C:\\Program Files\\Common Files\\Skype for Business Online\\Modules\\SkypeOnli<wbr />neConnecto<wbr />r\\SkypeOn<wbr />lineConnec<wbr />tor.psd1&quot;,<wbr /><br />
<br />
then I entered, &quot;New-CsOnlineSession -UserName myusername@mycompany.onmic<wbr />rosoft.com<wbr />&quot;. I am prompted to enter my password and also a verification code (I'm using multi-factor authentication), which once entered, displays the session id and a few other session related bits of information. It is at the subsequent Windows PS prompt that I enter the cmdlet and get the error.<br />
<br />
I am trying to do this using a Windows 7 64-bit SP1 PC.<br />
<br />
Thanks again for the assistance!

<div>
You need to be a SfBO admin or Global admin in order to run the cmdlet.
</div>


<div>
I am using an account that has those privileges.
</div>


<div>
Try a different account then? Here's how a sample output should look like:<br />

Tried two accounts known to hold the permissions you described. Might be the Powershell I'm using. It's Windows PS 5.1. Thanks. I'll keep trying other methods.
</div>


<div>
Well, I totally forgot that they added this to the SfBO Admin portal (too used to Microsoft Teams nowadays). So try this: Office 365 Admin Center -&gt; Admin Portals -&gt; Teams and SfBO -&gt; Open legacy portal -&gt; Reports -&gt; Session details.
</div>


<div>
Thanks. That looked very promising, but when I selected users who showed a fair number of a SfBO sessions in the Reports-&gt; Usage -&gt; Skype for Business Activity report, it returned &quot;no data.&quot;
</div>


<div>
Should have also said I selected a from date of about 60 days ago, so there should have been a lot of data for this user. I also tried several other users who show a higher level of SfBO activity.
</div>


<div>
Seems to work fine for me, but it's not uncommon for reports in O365 to be missing some data. You can always open a support case to get this investigated.
</div>


<div>
So, I just got this working in PowerShell. I used the &quot;Windows Powershell ISE&quot; launched as administrator. I ran this script to connect:<br />
Set-ExecutionPolicy unrestricted<br />
Import-Module SkypeOnlineConnector<br />
$session = New-CsOnlineSession -UserName xxxxxx@xxxxxxx.com (replace x's with your username and tenant domain)<br />
Import-PSSession -Session $session<br />
<br />
I ran the cmdlet you mentioned on my own O365 account. I see the Skype activity listed. Now, what would really be helpful is to tally the total number of IM messages (not sessions) from a given start date. Is there a way to do that?

Our company uses O365 for all employees. One app we use within it is Skype for Business. We would like to get a report showing how many individual messages a given user sends from Skype. The MS reports only seem to provide session counts. I know in the conversation history you can see the messages sent/received, but to manually scroll through Inboxes and count these is not practical. Are there any PS scripts for this?<br />

Thanks for the assistance in advance!<br />

Report showing individual message count per user in Skype for Business

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms". Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).

Chat / IM
