Add microsft teams link in sharepoint menu for external users

Hi all

I hope to help.

For Access to Teams as guest user (Web Access, Teams web app) for another Teams of another Tenants, you need to use this link:

https://teams.microsoft.com/_?tenantId=<tenantid(xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)>

I tested it and Works fine in my case. I have Access to another teams of another tenants and I put different links to a SharePoint site and when I use these links, the system says "Do you want to change to <another tenant>? You may need to log in again", press yes and you Access to Teams of the other tenant.

The tenant ID appears as part of the invitation link sent by email.

Bye.
