Thats not the tenant ID. The tenant ID is a alpha-numeric unique Identifier.

    I’ve signed up for a few things (TAP/Preview) asking for the “tenant ID” and it’s been that, how do you get the alpha-numeric you’re talking about?

      Thanks for comment, looked into this further and have added details for the alpha-numeric ID :-)

    FOR THE LOVE OF GOD- THANK YOU. I’ve been searching the net for ages, and all google gives me is azure bullshit, thank you so much from the deepest of my heart. How hard can it be to simply provide such info easily via technet hah..

Thanks for the info – it really helped. After using your method I was digging around on TechNet for S4B client policy information that can be queried by TenantID and I located the following powershell command

Get-CsTenant | Select-Object DisplayName, TenantID

This requires a S4B PS remote session to use:

$credential = Get-Credential
Import-Module SkypeOnlineConnector
$sfboSession = New-CsOnlineSession -Credential $credential
Import-PSSession $sfboSession

Good article!

My team really got sick of trying to find the tenant Id for our O365 and Azure projects. The devs, the support team, the sales team, everyone needs it at some point and never remembers how to do it.

So we build this helper site in the same vein as Hope you find it useful!
