This article describes how long it takes for Microsoft Office 365 federation to be applied across the organization.

• Okta Integration Network (OIN)
• Microsoft Office 365 (O365)

While changes made in Okta will be applied in real time, Microsoft's domain federation settings updates can take a variable amount of time. Most commonly, Microsoft applies the updates within a minute, but sometimes up to 24 hours.

If timing is critical to the deployment plans, reach out to Microsoft support to ask about the performance expectations for the Graph API endpoints, which initiate those federation changes described in the articles below:

• Update internalDomainFederation
• Create internalDomainFederation
