How to get your Microsoft 365 Tenant ID

Update 2019-09-09: Add SharePoint REST API

What is a Tenant ID? When you subscribe to Microsoft 365, Microsoft provides you a full environment with several services (SharePoint, Teams, Azure Active Directory, etc.). In order to link all of these services between them and on your environment, they use a unique identifier which is your Tenant ID.

The Tenant ID is represented as GUID: 00000000-0000-0000-0000-000000000000

Generally, you do not need to know your Tenant ID but sometimes, essentially for the developers or when your company needs to deploy an app (ex: enable PowerBI Microsoft 365 Usage Analytics), you need to.

How to retrieve your Tenant ID? Here, some ways to find it!

Azure Active Directory

By default, all the users of your company have access to the Azure Portal.

Once you are connected to your https://portal.azure.com, click on Azure Active Directory, then Properties and this is the Directory ID

Microsoft 365 Admin Center

[note]Note

For the users accounts with at least the Reports reader role

Once you are connected to your https://admin.microsoft.com, expand Reports from the left navigation and click on Usage. At the bottom of the page, you should find the Microsoft 365 usage analytics with your Tenant ID.

SharePoint Admin Center (App permissions)

[note]Note

For SharePoint administrators only

Once you are connected to your SharePoint Admin Center (https://yourdomain-admin.sharepoint.com), click on Classic features from the left navigation, then click on Open under Apps section and click on App Permissions (last link).

On this page, you will see some Apps with a unique identifiers. Each identifier contains a claim with an ID followed by an at ("@") and your Tenant ID (ex: i:0i.t|ms.sp.ext|00000000-0000-0000-0000-000000000000@YOURTENANTID)

SharePoint site

It is a little bit more complex to find the Tenant ID from a SharePoint site but you can do it too.

Web Inspector

Open any modern SharePoint site (or classic) and open the Web Inspector / Web Developer Console

• On Windows, it is generally F12
• On MAC OS X, it is generally CMD + OPTION + i

Once opened, launch a search on "siteSubscriptionId"

• On Windows: CTRL + F
• On MAC OS X: CMD + F

Rest API URL

Firstly, open your favorite web browser and go to any SharePoint site collection then, edit the URL like this:

https://contoso.sharepoint.com/sites/mysite/_api/SP.UserProfiles.PeopleManager/GetMyProperties

[note]Note

Replace contoso by your own domain name.

the result will be a little bit huge... But perform a search on "SPS-DistinguishedName":

here an example of the value (the first OU correspond to your Tenant ID):

CN=00000000-1111-2222-3333-444444444444,OU=[YOUR TENANT ID],OU=Tenants,OU=MSOnline,DC=SPODS0123456789,DC=msoprd,DC=msft,DC=net

Teams

All the users who have a Microsoft Teams license can reach their https://portal.office.com and click on the Teams tile or access it directly from their Desktop application.

Once connected to the application (web or desktop), you can show your Tenant ID by sharing:

• Team
• Channel

Click on the ellipsis on the right of Team or Channel and click on Get a link ...; at the end of the URL, you will see your Tenant ID.

PowerApps

All the users who have a PowerApps license can reach their https://portal.office.com and click on the PowerApps tile.

Once redirected to the PowerApps home page, the Tenant ID is visible from the URL.

Flow
