If your company has multiple Outreach orgs, there may be some additional considerations when setting up SSO. This document will cover the most common scenarios, but if you have something that isn't covered, feel free to contact our Support team directly for additional assistance.
If your Outreach orgs have no users in common
In this case, you'll simply need to create an application for each org in your SSO provider's interface and your users will be assigned to one or the other. No additional setup steps should be necessary and each user should only see the org they are assigned to.
If your Outreach orgs have common users
In this case, you'll need to use a custom email address for the second organization so that the two addresses aren't identical. For example, if the email address you use for the first Outreach instance is "email@example.com", your address for the second instance could be "firstname.lastname@example.org." You'll also need to set up the second instance of Outreach to use a NameId instead of email, as described in our article: Advanced Settings For Identity Provider (SSO).
