Question: When creating a push group in the Office 365 Okta app, it only creates a security group in Office 365. 
Is it possible to push the Okta group to Office 365 as a distribution list?

• Okta Classic Engine
• Okta Identity Engine (OIE)
• Microsoft Office 365 App
• Push Group

• Distribution groups cannot be directly created in Okta as Okta doesn't have multiple types of groups.
• When pushing Okta groups into Office365, they are being created as Security groups.
• Distribution lists can be synced to O365 but only with Universal Sync enabled, and they have to be AD Groups (i.e., need to create the Distribution groups in AD. That way they will sync from AD into Office365 via Okta), Okta groups can only sync to O365 as security groups, not distribution lists.
