Integration with SuccessFactors

Hi Community

We have SuccessFactors and we have four different Azure's.

SuccessFactors can only connect to one of these (Its for SuccessFactors Recruitment Integration to Outlook)

Does anyone know a way that I can connect the three other Azure's to our main company one, so that SuccessFactors can connect to our main one, then can see / post to Outlooks that exist on the other three?
