SharePoint Online and B2b

[Off2w0rk]

Hi all,

we need to grant 1200 users from TenantA access to a sharePoint online site in TenantB.

Currently, the only way i know of is:

1. Add users using csv file

2. Add 1200 users to a Group

3.Grant that group access to the sharepoint site.

This requires a lot of step and 1200 users have to click accept link. Then we have to wait for all users to populate as external before we can add them to the group.

Is there another easy way?

Is it possible to create an app with direct sign on link to a sharepoint site?

Like Direct sign-on links?

Not sure if there are other ways but this would do the trick but isn't without cost and technical setup.
