How to upgrade users coexistence mode to Teams Only using PowerShell

Today I dscovered that not every user in our tenant had coexistence mode set to Teams Only, despite the Org-wide setting said so. Bah! the users own setting overrides the Org-wide. Great, just another thing to remember…

We are a buch of users. And being lazy when I can, I need to brush of my skills in…


Time to dust off some old PS-skills and get cracking. Okay… not skills per say, but I manage to fiddle my way through it in the end. Google tells me that the cmdlet Grant-CsTeamsUpgradePolicy will do what I need in this case.

Opening PowerShell as Admin and connecting with these commands:

Import-Module SkypeOnlineConnector
$sfbSession = New-CsOnlineSession
Import-PSSession $sfbSession

As a prerequisite, you need to install this Skype-module: https://www.microsoft.com/en-us/download/details.aspx?id=39366

Before we do any changes i need to be sure the Org-wide setting really is set correctly with this cmdlet: Get-CsTeamsUpgradePolicy -Identity Global

Looks good to me!

The next step is to list out the users and see who have wrong coexistence mode: Get-CSOnlineUser | select UserPrincipalName, teamsupgrade*

Yup… almost everyone looked like this

I need them to look like this:

That’s more like it!

The cmdlet for changing this is quite simple: Grant-CsTeamsUpgradePolicy -PolicyName UpgradeToTeams -Identity your@name.com (Just remember to change that last bit…)

But do you need to do this on every single user one by one? Well, no. This is PowerShell! I used this little trick to go through every user and set correct coexistence mode:

$userlist = Get-CSOnlineUser
foreach($User in $userlist)
Grant-CsTeamsUpgradePolicy -PolicyName UpgradeToTeams -Identity $User.SipAddress

After this had looped through all of my users I verified that all users was set to the correct mode. Job complete!

A little disclaimer. I am NOT a real coder. This little piece her got the job done for me, but I’m sure it could’ve been done more sexy somehow. Feel free to show me in the comments!
