Finding Your Microsoft Teams Tenant ID - Get Link to Team
Sometimes it is helpful to have your Microsoft Teams Tenant ID when debugging issues with your Live Chat service or other software tools that required the tenant id. We can use this tenant id to look up your account, so we'll show you how to gather this information from Microsoft Teams.
First, within Microsoft Teams, select the Teams icon in the left navigation. Then choose a Team and select the 3 horizontal dots next to the team name. Once you click the icon, you'll see a popup with an option to 'Get link to team'. Choose this option.
Once you select 'Get link to team', select the Copy button. You can paste this link to any text editor. Included in the URL
Once you have the link to your team, it will look similar to this:
https://teams.microsoft.com/l/team/19%3a8f9b982085b440f1a1e34fe53b84dbc4%40thread.skype/conversations?groupId=0efcc002-6001-4a21-991b-8ba10bac0612&tenantId=421c85c3-3791-4b2d-5dd6-6fa64bc1b231
As you can see it includes a tenantId parameter on the URL. This is your Microsoft Teams tenant id.
