  Hi D_G_Tal!

  Would you please tell us if your Skype for Business environment and the company 1 is in the same forest?

  The following picture shows your scenario, right?

  
  

  It recommends you deploy the resource forest with Skype for Business, you can try to follow these tips:

  1.Establish a two-way trust between the resource forest and user forest(company2.com)

  2.Create DNS zones for company2 in DNS Server

  3.Sync AD property between Skype for Business and company. You could use FIM to do the sync for AD

  4.Enable users in Lync resource forest

  For more details about deploying resource forest setup with manual sync configuration, please refer to:

  Hi D_G_Tal!

  Thanks for your feedback!

  And as my first version of the reply stated, you can deploy the forest where the SFB Server is installed as a resource forest and deploy another forest as a user forest to complete it.

  The Official document provides this topologies for your reference:

  For more details, you can refer to:

  Hi D_G_Tal!

  You can refer to these documents to deploy it and it works for me.

  https://docs.microsoft.com/en-us/archive/blogs/saleesh_nv/lync-2013-resource-forest-deployment-with-manual-sync-part-1

  https://docs.microsoft.com/en-us/archive/blogs/saleesh_nv/lync-2013-resource-forest-deployment-with-manual-sync-part-2

  https://docs.microsoft.com/en-us/archive/blogs/saleesh_nv/lync-2013-resource-forest-deployment-with-manual-sync-part-3

  https://docs.microsoft.com/en-us/archive/blogs/saleesh_nv/lync-2013-resource-forest-deployment-with-manual-sync-part-4

  In my experience, you only need to have a certificate name with Company1.com as Skype for Business Server is deployed on this forest.
